      I would first check the slow blow fuse on the Ysus board. If it is ok I would check the input voltage coming from the power supply. The correct voltages may be printed on near the connector.

          That looks like a serious overload

              That failure is usually caused by bad buffers. Post pics of the buffers. They may be causing the shutdown.

                  Hi I notice that some resistor on the y-main board was flatten and the resistor are light dark I test the first 4 resistors and don't give me a value I think the board is damage I test the burn board and all the resistors give a value

                      you must change both buffers and y at same time. also i have seen the z all so be bad.unplug the y from the power supply and check your voltages, then unplug z all so ,and check the voltages again, if the z board is pulling it down...u need to replace all three at same time.

                          Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                          by Mgiffune
                          I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                          I ordered a supposedly ‘new' Tcon board this time, and                          ...

                          Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
                          by HTR-Informatique
                          Hello,

                          YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

                          I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

                          On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

                          I also changed the screen because the PC fell and the screen was broken.

                          I changed the battery with a new and original battery.

                          I also had corrosion/oxidation on the...

                          Problem

                          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                          Samsung UE50KU6070 black screen
                          by totof
                          Hello,
                          I have my TV model UE50KU6070 which I am trying to repair.
                          BN41-02528A / BN94-10800C motherboard.
                          If I disconnect the motherboard from the power board, the backlight works. When the motherboard is connected the backlight works but the screen remains black.
                          When I plug the TV into the electrical outlet, the standby LED lights up but no reaction to an attempt to start it with the remote control for about 1 minute. During this minute the TV consumes about 20W.
                          After one minute the consumption drops to 0W and the TV can turn on with the remote control but...

                          Hello everyone !

                          My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff. I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...
