hello everyone, i have a problem on this motherboard on the 12v. The pc doesn't turn on, the leds do for a microsecond but then they turn off and I noticed that the 12v is missing, the problem is that I don't understand where it is generated from. Do you have information about it?

Hi there !
I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...10-08-2024, 11:58 AM -
Hello everyone,
About me, my goal and the equipment I (don't) have:
I am brand new to this forum, and I am eager to learn about repairing laptops. I have an engineer background although I haven't done electronics for a while. I have watched several Youtube videos in the last two months, trying to understand how to diagnose a faulty motherboard. I have a USB-C Amp meter and a classic multi meter. No DC Power Supply to inject voltage, no soldering iron to replace components.
About my issue and my goal:

I got the TV from a friend. He claims that no image but sound from the TV.
I confirmed that when shine a flashlight on to the screen, I can see the image. And this should be backlight problem.
I open up the TV and found a few leds failed. And now I am ordering a new set of backlight strips for it.
But there is something that I do not understand when checking the leds. I do not have an led tester. I only use a bench power supply. I first set the voltage to 3V and current to 10mA. I could not light up the led until I increase the voltage to 12V. I understand most... -
Recently I discovered my SSD died (OCZ/Toshiba 240 GB). It was in a USB enclosure, attached to the Linksys WRT-AC1200 router. Since then I removed the USB enclosure and attached it to my Win7 PC (AMD 8150 CPU, 970 chipset, 64 GB RAM). I also gathered one or two other USB enclosures to figure out what is going on.
(I suspect that I lost quite a few MP3 and FLAC files I recently ripped from my audio CDs, I think I lost very little un-replaceable stuff.)
I think it is IMPOSSIBLE for Win7 to have any problems with a USB enclosure as long as Win7 knows how to speak to the... -
