Mr. Fixer

GIGABYTE RTX 5090

Problem: NO DISPLAY

Description: Unit was brought in by owner due to no display. As tested and confirmed by owner, unit is detected, and error 43 shows up in device manager.

After visual checking, found that unit is still fresh, no prior repair done. All voltages present, as well as all signals are working flawlessly.

Ran diagnostics and found one memory channel is problematic.

The issue with these heavy cards, since the 3080s woild be the weight of the heatsink vs the card. These humongous cards are putting unnecessary strain on the card itself, that a simple bump or simple mishandling would damaged the solder balls.

Reballed the ddr7 manually as my stencil is still for shipment.

Solution: Reballed 1 memory chip, repasted, unit back in action.

GRAPHIC CARDS, Macbook, Laptops, & Desktops
EXPERT BOARD LEVEL REPAIR

Biglang no display?
May power pero walang boot?
Nag-artifact na yung GPU habang naglalaro?

Hindi lahat ng ganitong issue, kailangan agad palitan.

Sa Mr. Fixer, focus namin ang motherboard at GPU board-level repair — meaning component-level diagnosis, hindi agad part swap.

Services include:
• Desktop Motherboard Repair
• Laptop Motherboard Repair
• Graphics Card (GPU) Repair
• No power / No display cases
• Shorted boards and power rail issues

Alam namin kung gaano ka-frustrating kapag down ang rig mo — lalo na kung may project, ranked game, tournament, stream, or backlog ka pa.

Instead of guessing or replacing agad ng mahal na parts, we check the actual fault.
Kapag repairable pa, we restore it properly.
Kapag hindi na practical, we’ll tell you straight. Ang goal ay magawa ang unit, hindi bentahan ng kung anu anong piyesa. Makapagdesisyon ng tama ang customer kung gagawin pa ba, o mas magandang palitan na.

Walang hype. Walang overpromise. Just proper diagnostics and responsible repair.

Item name: Zotac 3090

Problem: No Display

Description: unit does not display. Verified unit is detected, but registers error 43 on device manager.

3080s and 3090s are notorious for shorting out the chip’s memory controller so I was not optimistic on this one.

Resistance checks surprisingly shows memory is still ok. Voltage check however shows nothing.

Turns out memory pwm controller not functional. Detailed checks yield missing enable signal. Trace indicates a failed compnent that shorts out when voltage is applied.

Solution: Replaced offending components. New paste applied. Issue Resolved.
