Hi guys.
I ordered used LG 34UM88 monitor which should come with 19V 5.76 A adapter from LG.
I payed for monitor but sadly I got scammed it came with 14V 58W Samsung adapter.
Luckly I did not even tried to turn on monitor, but I think they used the 14V adapter.
Is it possible to use 14V adapter and what already damage could happen?

I've several amplifiers of different sizes which are faulty. I haven't fixed them because I haven't a clue. This is the smallest culprit. 240v in (UK) and 12v dc to the board. Small neon lights when power button is on. Different dc voltages across all of the capacitors. Where do I go from here?Yesterday, 04:43 AM

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 have this board from a colleague, with a short in O2U2 GPIO, it was replaced. But when you turn it on it turns the fans at times as if it wants to display video on the screen, but the loop restarts. If someone has a backup it would be great.Yesterday, 06:40 PM

Hope this is the right place, someone can help me.
My laptop started having a really strange problem....
When I turn it on the fans start working at a crazy rate and with random breaks...
They can work for say 10 seconds and stop for 2 seconds and then turn on again for 5 etc...
And it's from 0 to 100%. I tried to install AIDA and did the processor chip test and the graphics did not exceed 70 degrees and the fans were not even close to working at the power they work randomly.

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?

Hello,
I have replaced the psu on this Toshiba 42HL196 twice. I have no HDMI or tuner. The component and composite inputs work though. I had a spare seine but it just gives me 3 red blinks so it's either a faulty seine or needs programming. It would seem it's the seine board. Ideas?Today, 01:34 AM -

Hi,
I'm trying to locate the Bios chip on my T495s 20QJ to recover the Bios.
The computer shut down during the bios update, now it's just singing. I want to try to reprogram it. I've read the BIOS guide but I'm still missing some information. I hope I'm asking in the right place.
Do you now which one of those chips is the BIOS ? And, are those compatible with the CH341A ?
Thanks a lot !Today, 05:27 AM -

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 -

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
