Hello everyone,
This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.
My patient is an A2338 Macbook Pro M1 (late 2020).
It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...

Hi, my TV image started showing those lines and the image faded away, but sound is still coming from it, what could be the cause and is it fixable? I thought it could be the tcon board but I red on the internet that it could be a failing panel

Hi all,
I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source.
Thank you in advance.
BR,
Michele

A customer called me up and said that half the screen was like a shadow - presumably the backlight has partially gone. I've never done a repair like this on a monitor, only circuit board based repair on Macbooks etc - is it something that's doable or generally not?04-23-2024, 03:52 PM

Hello,
So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess
Its a ASUS P5VDZ-MX board.
I would really appreciate some assistance on what the best replacement caps would be for these:

Hello everyone.
I'm troubleshooting a cisco switch, which seems to have an issue with the PSU.
The psu has the following power rails - +12v, -53.5V and +3.3V
When connected to power, the +12 and -53.5 seem to work fine, but the +3.3 starts at ~3v and then goes down to ~0 (I guess this is the cap discharging). This happens both when the cable is connected and not to the switch board.
Any ideas what might be causing this behavior?

Hi community! Germany calling
I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!
I have a KD-65X9005A Sony 4k LED TV.

HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...03-20-2024, 07:29 AM -
Hello,
I have this Thinkpad T15p Gen 3 laptop. It starts normally with keyboard lighting up, I can hear the fan starts spinning, amps quickly reach about 1.7A without the battery, CPU gets hot. However, it is not posting.
