The Samsung UE40D5500 reboots after 2-5minutes (turns off for a second and then boots up). To me it seems like it can be psu LED protection circuitry issue most likely or somekind of mainboard fault (tv has the neeest firmware, but maybe eeprom or nand chips are playing tricks). Before I remove all led protection I am looking for guidamce about the repair and what could be the real cause and whether or not my assumptions are correct.

Hi guys,
I am having problems with an Corsair AX850 Gold PSU. I have had the PSU FOR around 8 years but it had not been used much. This PSU was used to power two video card and an i7 CPU originally. I noticed that the 12v power was going as low as 11.4v and the 5v was going lower than 5%. I was getting random reboots. I found that the motherboard socket had bent pins and one actually broke. Therefore, I assumed that was the problem and not the PSU. I rebuilt a whole new system. This time AMD. I decided to use this PSU since I had it.
Now with the new system I am still... -
Hi!
Asus B85M-GAMER absolute no hdmi output (not at start, not at Windows), and random restarts. Everything work, except hdmi and random restarts after 0.1-3 min. Restarts even in bios. On VGA Windows boots up fast, games and apps starts ok. Mem, psu, cpu changed, no luck. I need shematic, because i think the restarts caused by the hdmi failure. -
Hi everyone,
I've got a problem with my Asus TUF Gaming FX506LX laptop. I bought it as a non-working unit it had been completely drenched in a sweet alcoholic drink and was left for a year... When I got it, the motherboard wasn't in terrible shape, but I had to clean a lot of areasβabout 1/5 of the motherboard. There was some corrosion, but I managed to clean it up and re-soldered where I saw issues under a microscope.
One of the two primary MOSFETs was fried (PQ33 fried and PQ34 were fine), so while I was waiting for a replacement, I desoldered it and created a short.... -
I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).

LG Gram 15Z980 picked up on Ebay for $200 (was sold as parts because no M2 drive and bios pw locked), but otherwise intact and working.
Threw a 500gb M2 in, and was able to install Windows. On Gram, Win activation is stored in the bios, so Windows was automatically activated. I still kept getting random bsod's. Also bought a pw and unlocked the bios.
Upgraded Windows to 11, still didn't solve the random & frequent bsod's. Cleaned & reseated all cables, RAM, etc... still getting frequent bsod's. Bought & installed a new stick of RAM, still getting frequent...
