I've been working through an issue with my 42"LG. The initial symptom was that I had lost the picture but still had sound. I jumped on this forum and with some searching it looked like a Y or ZSUS board issue. I found an open fuse on the YSUS board but all looked good on the ZSUS. My other observation was that I got a sag in Vs (168Vdc) just before shutdown. I checked the power supply outputs and all were spot on otherwise. I sent the suspect board to Coppell for repair, but after re installation the same symptom remained. At this point I ordered a ZSUS board from Coppell and a buffer board. So long story short after installing these components still have the same issue. So now I'm looking at the control board and have made a few observations. First, if I disconnect the input to the control board the set will remain on with a white screen and a normal Vs of 186Vdc (per sticker on chassis). Also I noticed that there are four LEDS marked D12 through 15. All are solid green except D15 which is not lit. Is this normal or am I looking at a bad board. Any input from you guys would be appreciated. Warren

Hi everyone,
I am trying to fix a samsung washinmachine power supply main board.
I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.

The power supply board reference is the following: DC41-00189a

Hi everyone,
Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.
Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.
I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue.... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
