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:
A friend of mine has a MacBook Air M1 A2337 that does not... -
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... -
Need help to solve some problems with this laptop.
After working in bed with it one night and heating up too much (probably the cause of this problems) the sata HDD OS windows froze
After restart the original Sata HDD was not recognized anymore (but works fine in other laptops or PCs)
Tried connecting other good Sata 2.5 HDDs but not one is working in this laptop anymore (not the original nor others)
Before this had happened I observed some other problems:
When I tried replacing original mecanical HDD with a SSD HDD could not get them...
