Hello, I am back again, sorry for disappearing!
I was working on an Asus motherboard which might have a bad PCH.
So I had this Graphics card which seems to be showing something on the screen but it's full of artifacts, and I decided to make a new thread because I was in a wrong path!
I reballed the A0 channel, and then removed both A0 and D1 vram chips and the card is still showing the same artifacts with only a bit of change on the corrupt lanes.
I am starting to suspect the core.
I tried tserver memfa test but it gives me an error :[B] [error][Framework]...

Hello, I was updating the bios on my t470 20jn pf1q6dx5 using the soic8 clip that came with the Ch341A on the bios and pressed the clip too far back when i was taking it out and it knocked off what look like little capacitors, can this be repaired or bypassed with solder or a wire or what was originally on there, they are extremely small. I have attached two pictures, one with the capacitors on and one with them off. It took me weeks to figure out why the board wouldn't power on. I thought I had broke the bios. THe machine turns on for a second then turns off.

The laptop won't start. When plug power supply, on 19V in gives me 0,14A, without turning on the laptop.
I check it with thermal camera, and there is one resistor that is very hot, I change the resistor with new on but the result is the same.
In the attachment there is schematic of the resistor area, and schematic of the laptop.
I can't understand, why this resistor is getting so hot....Today, 01:24 AM -

I can't seem to flash a new BIOS normally with the .exe file provided by Lenovo, so I'm looking for help. Every time I try I get an error message that reads "New BIOS region (1000000h) does not match with current (C00000h)"
I've extracted the .bin files from both the UB1/UB2 chip (8MB) and also from the UB3 chip (16MB) using a flash programmer although I am not sure if both need to be flashed or just one. Can I get help getting working .bin files from the latest BIOS version for each chip respectively to see if that works? I've extracted the bios.fd file myself and then...05-03-2024, 12:07 PM -

Hello,
I am new to repairing computer electronics, so excuse any mistakes I make.
A friend of mine had a broken graphics card (MSI Radeon RX 5700 XT MECH OC) and gave it to me. It does not power on or show any signs of life.
I identified what looks like the remains of a blown capacitor at the bottom of the board (see picture).
I wanted to replace the capacitor, but I have two questions:[LIST][*]Does this repair have a chance of working? or is a blown capacitor a sign something else is wrong?[*]How do I determine the rating/value of this capacitor?...Yesterday, 09:56 AM

Hi All
Been a while since I have been here, and a bit rusty.
I have the above laptop motherboard that was working and now the charging circuit is faulty.
Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.
I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off
Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...05-03-2024, 03:25 AM -

Hello Guys,
I am not familiar at all with plasma tv's but i tried my luck anyway since business is so bad. We gotta try, right?
Anyway, the original problem was a tv clicking and not starting due to a short circuit on the Z-Sustain board (on the right side from the rear).
I found two transistors shorted (30F123) and changed the gate driver ic's as well. I think they were FAN73711. I soldered for dry joint on power supply, Y-Sustain and Z-sustain. Started up the TV and the short was gone so i had an image but.....
Lots of colorful speckles on the image and also there...Yesterday, 11:01 AM -
