Sha Tin GPU Repair: How to Get to Shek Mun, Drop-Off Flow, Inspection, Quote & Warranty Explained

2026-10-18 ｜ GPU Repair ｜ 13 min ｜ HK GPU Fix Editorial

Key Takeaways

HK GPU Fix has one shop: Room 1209, Dali Plaza, Shek Mun, Sha Tin, about a 2-minute walk from Shek Mun station. Walk in or send the card by SF Express. Inspection is free, a detailed quote follows by WhatsApp, work starts only after you confirm, and the actual fee is always the post-inspection quote.

Introduction: One Shop, One Workflow

This guide answers the four practical questions every first-time sender asks: how do I get to the shop, what do I bring, what happens after I hand over the card, and what does the warranty cover. Everything below follows the shop's published pages: the contact page, the pricing page, the mail-in page, the warranty policy page, and the terms of service. Where those pages give a range rather than a single number, this guide keeps the range. Where they say "per the post-inspection quote", this guide says the same.

One point first, because it clears up the most common confusion. HK GPU Fix has a single shop in Hong Kong. Other place names that appear on the site — Mong Kok's Langham Place, Grand Century Place, Mongkok Computer Centre, Harbour City, Elements, the ICC, Olympian City, Sha Tin's New Town Plaza, The Wai, Ma On Shan's MOSTown and others — are described as drop-off or service coverage areas, not branches. All repair work is carried out at the Shek Mun workshop, and work is not outsourced to a third party.

Where the Shop Is

• Shop: HK GPU Fix
• Address: Room 1209, Dali Plaza, Shek Mun, Sha Tin, New Territories
• Phone: 2186 8010 (+852 2186 8010)
• WhatsApp line: +852 6558 6806
• Opening hours: Monday to Sunday, 11:00–20:00, including public holidays

Use the address exactly as written above. The contact page, the English translations, and the map search string all use this spelling. For phone and WhatsApp, the site lists the shop phone as 2186 8010 and a WhatsApp line as 6558 6806; if anything is unclear, go by the website's contact page.

Getting to Shek Mun

The shop's published direction is simple: take the Tuen Ma line to Shek Mun station, then walk about 2 minutes to Room 1209, Dali Plaza. The site does not name a station exit, and this guide will not invent one. The reliable way to navigate the last few minutes is to search Google Maps for the Chinese address string "沙田石門達利廣場1209室" and follow the walking directions it gives.

Within Sha Tin, the shop's own travel notes describe the following: Sha Tin station, New Town Plaza, Che Kung Temple, and City One are a few stops away along the Tuen Ma line; Tai Wai and The Wai are about 10 minutes away; Ma On Shan and MOSTown are about 10 minutes away; and from Fo Tan the route is the East Rail line to Tai Wai, then the Tuen Ma line.

The shop also publishes reference journey times from other districts. These are the shop's reference figures, not the MTR's official timetable:

In every case, add the roughly 2-minute walk from the station to the building after arrival.

If you are driving, Dali Plaza has a visitor hourly car park, which the contact page notes as convenient for carrying a heavy tower and graphics card. The site does not publish parking charges, the number of spaces, or the mall's opening hours, so this guide does not state them — check before you travel if parking cost matters to your trip.

Two Ways to Send Your Card

There are two routes, and both end at the same inspection bench:

1. Walk in to the Shek Mun shop. Bring the items listed in the next section, hand the card over at the counter, and the shop registers it on the spot.
2. Send it by SF Express from anywhere in Hong Kong. The mail-in route supports sending from an SF station or a smart locker, and collection from the shop is also possible. The delivery address for a mail-in parcel is written as: Shek Mun, Dali Plaza, Room 1209 shop (phone: 2186 8010). After posting, send the SF tracking number to the shop by WhatsApp so the parcel can be tracked.

There is no door-to-door or on-site service described anywhere on the site. The two routes are walk-in and SF mail-in. Do not plan around a home visit, a pick-up, or an on-site inspection, because the site does not offer them.

Before You Send It: What to Bring and What to Leave

What to bring

• The graphics card itself. The repair target is the card, not the computer.
• The power cable, where relevant. If the card uses a third-party 16-pin adapter cable (for example on an RTX 4090 or 4080), bring that cable too, so the engineer can test it and rule out a cable contact problem. Cards on standard PCIe 8-pin power do not need you to bring a power supply — the shop has a full set of test power supplies.
• Photos or a short video of the fault. Faults are often intermittent: artefacts in a game, a sudden black screen with fans spinning hard, or a Device Manager Code 43 may not reproduce on demand at the shop. A photo or video, plus a note of when the fault happens (at boot, in games, after a driver change), gives the engineer something to work from.
• The burnt connector, if the 12VHPWR connector has burnt. Bring the burnt cable end as well, and do not power the card on again. A burnt connector can be accompanied by a short in a power phase, and powering it again risks widening the damage. Bringing the cable end lets the inspection side judge whether the problem is the connector, the cable, or the power phase.
• The invoice or purchase receipt, if the card is still within its agent warranty period but the manufacturer has refused warranty (for example for a burnt 12VHPWR connector or human damage). It helps the engineer assess the situation.

Customers from the Fo Tan industrial area get a specific note on the site: bring the card only — there is no need to bring the whole tower.

What to leave at home

• The rest of the computer. The shop only takes the graphics card hardware itself. There is no need to leave your personal computer or SSD behind; the engineer tests with the shop's own dedicated clean test computer. Leaving the machine at home also keeps personal files and drives out of the trip entirely.
• Non-original accessories. Remove any non-original brackets. If a custom water block is fitted, bring the original air cooler if you can, so a bare-board test is possible. Put the gold fingers in a protective cover or a clean anti-static bag.

Online booking

The site has an online booking form. It asks for your name, a contact phone number or WhatsApp, the graphics card model, a description of the fault, and your preferred reply channel (WhatsApp, phone, or email). After booking online you receive a dedicated booking number; show the screenshot on your phone at the shop for instant registration. For a mail-in parcel, fill in the website booking form, mark it as an SF mail-in, and add the fault description to obtain an RMA number before posting.

Back up first

The card itself does not store personal files, but BIOS changes and personal settings can be lost if the card is reset during service. Back up BIOS modifications and personal settings before sending the card. The shop accepts no liability for any data stored on the card, including game saves or model weights, so backing up is your own safeguard.

Packing a Mail-In Parcel

Packing matters because the parcel travels without you. The shop's mail-in instructions are:

• Anti-static bag, plus bubble wrap of 3–5 cm (at least 3–5 layers), plus a carton.
• Write or attach the RMA booking number and a contact phone number on or in the outer box.
• Shake the outer box before sealing: if nothing moves inside, the packing is safe.

Do not substitute an ordinary plastic bag for the anti-static bag — static can damage sensitive chips, and the shop's own checklist makes the same point. The customer is responsible for packing the parcel according to the shop's instructions, and damage in transit is borne by the customer. The shop strongly recommends using SF's insured service, which it describes as covering up to HK$20,000. The site does not publish the insurance premium or the claims procedure, so this guide does not state them.

What Happens After Handover: Receipt, Inspection, Quote

Step 1 — Receipt and registration

When the shop receives the card, it scans it into its inventory system, and the system automatically sends an SMS or WhatsApp notification together with a dedicated RMA tracking number. For SF parcels, the shop videos the unboxing within 24 hours of arrival and keeps it on file as the receipt record. That unboxing record, plus the photos you took before sending, is the before-and-after evidence for the card's condition.

Step 2 — Free inspection

Inspection is completely free. If you decide not to repair after inspection, no fee is charged at all. The preliminary inspection is completed within 24–48 hours of receipt.

The inspection itself has three published stages, and the order matters:

1. Measure first, power on never blindly. The engineer measures the resistance to ground on each voltage rail before applying power, so that a short does not get a chance to break through the main chip a second time.
2. Thermal imaging. A low-voltage, high-current pulse is injected and an FLIR thermal camera locates the component that heats up — the shorted part.
3. VRAM diagnosis. A Linux MODS/MATS memory diagnostic reports the faulty memory channel or address, separating "the memory chip itself is damaged" from "the BGA solder joint is cracked".

The published inspection tools are FLIR thermal imaging, multimeter testing across all voltage rails, and an oscilloscope. Inspection is diagnosis, not repair: its job is to narrow a symptom down to a fault point, and the result can also be that the card cannot be repaired.

Step 3 — Quote, then your decision

After inspection, the shop sends a detailed repair plan and an accurate quote by WhatsApp. Work starts only after you confirm. The quote is valid for 7 days. The quote timing is given as within about 24–48 hours of receipt, or 1–2 working days — the pricing page and the mail-in page phrase it slightly differently, so this guide keeps both wordings rather than fixing a single number.

This confirmation gate is the core of the process: the quote is not a notification, it is a proposal you accept or decline. If you decline, there is no charge for the inspection. If the card is not repaired, the return postage is paid by the customer (HK$30–HK$60 depending on district).

Step 4 — Repair, stress test, payment, collection

Once you confirm, the repair goes ahead. Every completed repair gets at least 12 hours of FurMark or 3DMark stress testing to confirm stability. Payment comes after the repair is complete and has passed the stress test — at collection, or before a return parcel is sent. Payment methods are cash, FPS, Alipay, WeChat Pay, and bank transfer. The quote already includes the original-grade parts needed for the replacement (DrMOS, connectors, VRAM chips and similar).

Collection is either in person at the shop with the RMA number, or by SF return. Return shipping is paid by the customer, except for a re-repair inside the warranty period. If you need an express turnaround, the arrangement and fee are confirmed at quote time.

How long does it take

The site gives several time figures, and they describe different things, so keep them separate:

Do not collapse these into a single "average" number. The tier times are reference times for each tier; the terms figure is the general window; large jobs have their own longer window. The quote you receive after inspection is the figure that applies to your card.

The Three Tiers at a Glance

The pricing page publishes three tiers. The overall span from the bottom of Tier 1 to the top of Tier 3 is HK$400–HK$2,800. Every figure below is a reference range; the actual fee follows the post-inspection quote.

The tiers overlap: Tier 1 runs to HK$780 while Tier 2 starts at HK$480, and Tier 2 runs to HK$1,380 while Tier 3 starts at HK$680. The tier describes the depth of the work, not a price ladder — a complex Tier 2 job can cost more than a simple Tier 3 job. Which tier applies to a given card is decided by the inspection, not by the symptom name. A companion guide explains the pricing structure in full: how the tiers are defined, what a quote is made of, and why inspection comes before the quote.

Warranty: What It Covers and What It Does Not

The terms of service state that all repair items carry a 90-day non-human-damage warranty from the date of pickup or sign-off. The site's warranty pages also carry other wordings (a 30-day basic tier and tiered periods by item). This guide does not pick a single number and call it the whole-site rule: the actual warranty period for your repair is the one on your quote, warranty card, or RMA record. If anything is unclear, check with the shop against those documents.

What the warranty covers. The warranty is limited to the specific fault item of that repair. If the same part or circuit that the shop repaired fails again with the same fault, it is re-repaired free of charge. The warranty page lists coverage examples, including: the same repaired circuit area failing again; a BGA reball or expansion-soldered chip developing a cold joint; a re-soldered 16-pin connector melting again under normal use; and a PTM7950 service where the hotspot rises above 100°C again within 90 days, with a free re-application.

What the warranty does not cover. The terms list six exclusions: human damage (liquid ingress, dropping, impact, improper installation); faults the company did not repair; unauthorised third-party modification or disassembly; natural disasters (flooding, fire, lightning); secondary damage caused by a power supply unit fault; and damage caused by overclocking or voltage modification. The warranty page adds that removing the tamper-evident sticker or disassembling the cooler yourself is also not covered.

How to claim. Contact the shop on WhatsApp (+852 6558 6806) or by phone (2186 8010), giving the original RMA number and a short video of the fault screen. Then either bring the card to the Shek Mun shop or send it back by SF, marked as a warranty item with a priority RMA. After confirmation, the shop arranges a free inspection and re-repair. A warranty re-repair gets priority queueing, a 24-hour priority inspection, free replacement of the faulty part, and a 12-hour burn-in test. Repair records live in the shop's official RMA electronic system, where the RMA number or the card's serial number can be used to look up the warranty expiry date and covered parts.

The common misunderstanding to avoid: warranty does not mean "any fault on the whole card is covered". It covers the specific fault that was repaired, where the damage is not human-caused. It also does not mean every return in the warranty period is free of all cost — postage arrangements follow the terms, as set out above.

Edge Cases Worth Knowing Before You Send

• You decide not to repair. Inspection is free and there is no fee, but return postage (HK$30–HK$60 depending on district) is paid by you.
• A new problem is found during repair. The shop notifies you at once and provides an updated quote. Do not expect the original quote to silently absorb a newly found fault.
• The card cannot be repaired. If inspection confirms the card is unrepairable (for example the GPU die core is punctured with no replacement part), no hardware repair fee is charged, and the card is returned.
• You do not reply to the quote. If there is no reply or confirmation within 30 days of the quote being issued, the shop sends two reminders. If there is still no reply 30 days after the final notice, the equipment is treated as abandoned. After a further 30 days the shop disposes of it (eco recycling or secure destruction), after which it cannot be retrieved. If you need a longer retention period, contact the shop to arrange it. Do not read this as "no reply means instant destruction" — the three 30-day stages are all part of the policy.
• Damage in transit. Packing per the shop's instructions is your responsibility, transit damage risk is yours, and the shop's unboxing video is the receipt evidence. The SF insured service is strongly recommended.
• Sending from outside Hong Kong. Contact customer service first to confirm feasibility and shipping cost.

Common Misconceptions

• "There is a branch in New Town Plaza / Langham Place / The Wai." No. Those are service coverage areas. There is one shop, in Shek Mun.
• "The online price is the real price." No. Online figures are reference ranges. The real fee is the post-inspection quote.
• "Inspection costs money." No. Inspection is free, and declining the repair after inspection costs nothing.
• "The warranty covers the whole card." No. It covers the specific fault item repaired, for non-human damage.
• "I need to bring the whole computer." No. Bring the card only.
• "Mail-in has no proof of condition." The process has three layers: your own pre-send photos and serial-number record, the shop's unboxing video within 24 hours of arrival, and the RMA registration with SMS or WhatsApp notification.
• "Shek Mun station is the shop door." It is about a 2-minute walk, not inside the station. Navigate by the map search string, and do not rely on any invented exit letter.

Frequently Asked Questions

Do I need to book before walking in?

The site provides an online booking form and an RMA number system, but it does not state that booking is compulsory or that walk-ins are always accepted. The safe course is to fill in the booking form first, get the booking number, and show the screenshot at the shop for instant registration.

What exactly should I write on the SF parcel?

The RMA booking number and a contact phone number, on or in the outer box. After posting, send the SF tracking number to the shop by WhatsApp so the parcel can be tracked.

How soon will I get a quote?

Within about 24–48 hours of receipt, or 1–2 working days, by WhatsApp. The two phrasings come from different site pages; treat the window as the shop's stated range, not a guaranteed hour.

Does the online AI quote count as my quote?

No. The site's AI instant quote, AI temperature assessment, and AI chat functions are for reference only. The actual repair plan and fee follow the engineer's formal post-inspection quote.

If I decline the repair, do I pay anything?

No inspection fee. You pay the return postage (HK$30–HK$60 depending on district) if the card is sent back.

What if the card is still under the manufacturer's warranty?

Consider the manufacturer's own RMA route first as a general principle. If the manufacturer has refused warranty — for example for a burnt connector or human damage — bring the invoice or purchase receipt so the engineer can assess the situation. This guide gives no conclusion for any individual case.

How do I check my warranty later?

Use the RMA number or the card's serial number against the shop's RMA electronic system to look up the warranty expiry date and covered parts, or ask the shop on WhatsApp or by phone.
