Hi all,
I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
🔥 The Problem Started After Suspected ESD/PD Fault
I experienced a power issue or ESD event through a USB-C charger
After that, the NX20P5090 power switch was visibly burned and was replaced
Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
🧠 What I’ve Done So Far

Hello, I'm stuck in troubleshooting…
The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.
In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
When I press the flash button, it's detected by the system, flash icon appear on LDC display.... -
I usually try to figure these things out on my own but am asking for help now as I have been beating my head against a wall.
Backstory, I initially ended up with a CF20 Mk2 with a locked BIOS. I used aptio to read the BIOS and made the adjustments to the .rom file and attempted to write it back with aptio before reading other users problems with that setup. Well it bricked the BIOS go figure. Computer no longer boots, black screen. I found a clean BIOS on this forum but now I am having ME issues. So I would rather hand over the aptio dump(pre BIOS brick) and a hardware reader dump(post... -
Hi everyone. I've been given a dead Pana 55DX600u that I hope to save from landfill. I suspect the tcon board or UC1 on that board.
Set will flash green led and attempt to start, backlight gives a brief flash then set shuts down and red led flashes slowly. Voltages out of PSU look ok. TCon board gets 12v at fuse when attempting to start and 3.3v on L1 but main IC gets warm very quickly (heatsink/cover removed, felt with back of hand) during the second or two the 12v is applied before PSU shuts down. TVS diodes on lvds input lines are not shorted, no caps appear to be shorted. ... -
Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
TV Model: Panasonic TC-P55ST50
