I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor.... -
I'm not sure if I am posting this in the right spot, I don't have any question or anything specific to one board. I am *kinda* starting out with this kind of work. I have been IT in one role or another for my job the last 30 years, and I am familiar enough with basic board stuff generally speaking. So, I dunno for example if someone told me to find a uart header, or flash some generic tsop8 something, etc I understand that kind of stuff. Point being, I'm not 100% clueless. I just don't have the specific knowledge when it comes to some of these more advanced repairs. I actually have spent the last...

I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
Is there a way... -

GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
Found issue with a RAM block
Replaced, green lines gone.
Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
Used a good card to test and same results low errors 32+.
I am just search for some form of command to do a full test on the GPU.
I just ran the mats command with my good GPU and passed after roughly 40 min.
The repaired one, ran... -

I have a strange problem with my KVA2 RTX 2060 Super. As soon as Windows 11 is loaded, artifacts appear. Now the crazy thing: When I start Furmark the artifacts are gone and Furmark runs great without crashing. Mats test shows me no errors (PASS). Drivers can also be loaded without any problems.
Mods shows me the following error:
Code:MODS start: Thu Feb 1 19:16:00 2024 Command Line : gputest.js -oqa -old_gold -test 94 -dramclk_percent 100 -ignore_fatal_errors -run_on_error -fan_speed 70 -matsinfo
