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 Filesif you find these attachements useful please consider making a small donation to the site

For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

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

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... -
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 all,
Samsung 65" TV that randomly power cycles. It could be a few hours or a few minutes and then I hear a click sound and reboots. I have updated the firmware to the latest. I'm suspecting the power supply might have bad caps (hoping 🙏...). Inspected the PSU board and none of the caps have any bulging, leaking, or unusual noises that I can hear. Any suggestions? Thanks
PSU: L65X1Q_DHS / BN44-00627A
