This Lenovo V14 ADA came in completely dead with a black screen — no POST, nothing. After checking the basics, I traced the problem to a corrupted BIOS chip.
Instead of desoldering the chip or removing the motherboard, I used a pogo pin cable to reprogram the BIOS directly on the board. Quick, effective, and way less risky than traditional methods.
What's covered:

Diagnosing the black screen issue
Using pogo pins to access the BIOS chip in-circuit
Reprogramming without desoldering
Testing and bringing the laptop back to life

If you're into laptop repair, BIOS work, or learning alternative repair techniques, this one's for you.

Your laptop powers on, the lights come up, the fan spins… but the screen stays black?

In this video, we go step by step through four common causes of the dreaded “no display” issue — and how to fix each one safely. 🧠 Learn how to diagnose whether it’s:

1️⃣ A RAM or display connection issue

2️⃣ A BIOS or firmware problem

3️⃣ A failed GPU (Graphics Chip) or PCH (Platform Controller Hub) issue

4️⃣ Or a deeper motherboard fault

Each section includes real repair logic used in our workshop — no random guesswork, just solid, repeatable methods.

This was a challenging motherboard repair! This HP 15s laptop came in completely dead and was heating up around the PCH area — a common but high-stakes symptom.

😱 Someone had already worked on it, leaving flux residue near the CPU, so it looked like a lost cause.
But with careful voltage injection and the help of a thermal camera, I discovered a shorted capacitor causing the issue. After replacing the faulty cap, the laptop powered back on and is now working perfectly!

🎥 Watch the full repair process and learn how to diagnose and fix this kind of motherboard short step by step.

In this video, I repair a UNI-T Pro UTI260B thermal camera that was completely dead and not powering on.

The fault was caused by a shorted TPS63025 buck converter, the 3.3 V regulator that powers the main board. I show step-by-step how to diagnose the issue, test the faulty IC, and replace it to bring the camera back to life.

This problem is common in many UNI-T UTI-series thermal cameras and other handheld instruments that use the same power converter IC.

You’ll learn how to:
– Safely disassemble the camera
– Identify shorted power rails
– Locate and confirm a bad TPS63025
– Replace it and test the result

The repair restores full power and operation — saving an expensive device from the bin.

🧰 Tools used:
– Multimeter & lab power supply
– Hot-air rework station
– Fine-tip soldering tools
