Re: Samsung LN52A650 Visual Artifacts & Repeatedly Power Cycles
Ok, I am about to try the C102/C131 cap replacement fix. The C132 is shown in the best pic I can make and it is beside the C131 and I would like to know if its replacement is necessary? Last 2 pics are my board numbers.Attached FilesLast edited by captainKKK; 12-15-2021, 07:16 PM.Comment

Hi!! I have been given this old TV set.
When I hit the power button, the BL (as you know this is a CFL backlight) turns on, video works fine as I can see the LG logo show off, but the backlight starts going on-off for 3 times, when it gives up and turns completly off
This set has a inverter board on the top right corner. This inverter (or the tubes, I don't really know) buzzes very loudly during the second that the BL stays ON. I have posted a video, turn your volume UP!

I have checked voltages at the PS
All normal voltages... -
Background:
I found this TV by the side of the road saying it needed a new backlight. Thanks to the help of this forum, I was able to repair the backlights and the power board.
When I put the TV together, I noticed visual artifacts on the right side and a darkening of the center area, mostly on the right. Specifically, on the far right, the screen is very slow to refresh and has a smearing effect. I've taken video and will link that below. The photos show some of the afterimages that persist for a few seconds to a few minutes, again, on the right side mostly.

Hello,
I need help identyfing what is broken on this GPU - GPU core or VRAM. Let's start with what I did and know so far:
- disassembled, added missing SMD capacitors from same GPU
-(If anybody knows what Q518 is and would share this information I would be very grateful)
- artifacts during Windows booting are blue vertical stripes, I can take a photo if that would help
- artifacts in Windows are yellow-ish horizontal lines
- in BIOS/ text on black screen text gets extremely garbled
- GPU-Z doesn't show GPU or VRAM frequency
- GPU error 43... -
Hello (sorry for my bad English),
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

Hello everyone! This is my first post and this motherboard is driving me crazy because everything looks so non-trivial that I don't know where to start investigating. During these days I believe I watched half of the YouTube videos trying to understand how to troubleshoot power cycles but at the same time, I'm confused because my motherboard doesn't always do that and sometimes completes the POST for a few seconds: the right amount of time to freeze, show glitches on the screen, and then reset itself.
Let me give you a bit more context to understand why and how we got here.
