Samyoung are iffy - I've not seen any fail but they don't have a good reputation. They are a Chemicon subsidiary.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: dmtech LCD tv wt20xt switch's off randomly
ive ordered some anyway, because its so random its hard to test so just gonna replace the big ones near where the power comes in and see if that cures it, if not suppose it could be an invertor fault if when its getting warm its failing, but not really gave it a good test, so will change caps and retest for a couple of hours and see what happensComment

Re: dmtech LCD tv wt20xt switch's off randomly
replaced most of the big caps then tried it, didnt turn on, so carried on replacing all the caps like 10uf 16v etc on left hand side and im testing it as i write, it hasnt switched off yet and it powered up ok now so fingers crossed ive sorted itComment

This issue has me stumped! I have this Lenovo IdeaPad and the SSD (NVME) keeps on randomly disconnecting. It'll stop being detected in BIOS randomly and when I turn it off and back on sometimes it'll detect again and boot up just fine...only to crash after a few minutes and either boot again or stop being detected.
Things I tried so far:
- Reset the CMOS by removing battery, held power buttons 60 seconds, all that jazz.
- BIOS is fully updated (had to use CHA341 because I bricked it the first time trying to update it)
- Tried multiple working NVME drives... -
This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.
Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today.... -

hello everyone. please help i have a surface laptop 3 AMD model 1873 that randomly restart. i don't think it has bad CPU, because when tried to stress test by CPU-z it not restart or has anything wrong, it just randomly restart when normal use ( browser, or watch video....). i tried to replace U6701 and U6702 but don't see any thing change.
I'm tried to fine any glue on internet but no luck. I'm looking for any advice from you guy please.... -
Hello.
Have this A1398 emc 2876 that randomly goes to black screen and raising fan. I know this was problem of gpu or gpu voltage controller, but this one is without gpu.
Is there some known failure points on them or i just count on cold solder under cpu?
