      Yes, I've had this before due to poor PFC circuit fault. It will get worse as the PFC circuit drifts further out.

              I replaced the PSU because I had a spare one lying around.

                      Samsug washing machine. Power supply DC41-00189a board issue
                      by Soulzink
                      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.
                      Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
                      The power supply board reference is the following: DC41-00189a
                      I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel...

                      Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                      by Asraf Atb
                      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....

                      Customer plugged in samsung monitor into the board and used it as a power supply, killed UG800 and UG400. I replaced those two with an exact donor board we had In stock and working, board pulls 5volts and then gets like 2.89 amps on the left side. The singular port is the port that failed. Used a perfectly working chips from donor (board was locked) Now I only get 5volts 0 amps on that power and then 20volts 0 amps on the two left side ports, I checked for DFU and nope nothing, computer not turning on. No shorts present anymore. I am confused as I used the exact components from an identical...

                      TCL 55RP620K power board issue
                      by notallbad
                      Originally the tv arrived with dimmed backlights (not failed leds) but everything else worked ok. Adjusting backlight in menu did nothing but voltage changed on dimming control pins,
                      0% p_dim at 1.65v and a_dim at 1v
                      50% p_dim at 3.3v and a_dim at 1.65v
                      100% p_dim at 3.3v and a_dim at 2.88v

                      Changed backlight leds anyway as always like to have complete peace of mind they wont fail shortly after selling the tv. No change as expected!

                      Leds are 2 rows of 15 6v leds.

                      On inspection of the power board found diode MBR3200 shorted so replaced with...
