What is the Steam Deck black screen (BSOD)?

The device powers on but shows no image (sometimes only backlight). It is often a motherboard fault - problems with IC ANX7850B. We diagnose and repair this issue.

Can you upgrade my Steam Deck SSD?

Yes. We install a larger NVMe SSD, reinstall the system, and perform performance tests.

How long does a typical repair take?

Usually 1–3 business days. Motherboard-level work depends on parts availability and fault complexity.

Do you provide a warranty?

Yes, 3–12 months depending on the scope of work and parts used.

Frequent Steam Deck problems

Black screen – console powers on, no image, often faulty ANX7850B.
No video via USB-C – Dock not working.
Logo freeze – device stuck on boot logo.
USB-C port loose, no charging.
Overheating – loud fan, FPS drop.

Battery – fast discharge, swelling.
SSD – boot errors, upgrade needed.
Water damage – corrosion, shorts.

ANX7850B and black screen issue

The ANX7850B chip manages video output via USB-C. Failure leads to a black screen or no Dock support. In our lab we perform BGA replacement of ANX7850B using microscope-controlled rework stations. After repair the console is tested with Dock, HDMI, and stress-tested in games.

Cooling maintenance with Honeywell PTM7950

We always use Honeywell PTM7950, the original phase-change thermal pad from Valve. Unlike regular paste, it:

does not dry out,
keeps APU temps lower,
extends hardware lifespan,
reduces fan noise.
