Hi, friend. I have a samsung nu8005T that won't turn on with the standby light blinking. . If I disconnect cable from the main to the power supply I have constant backlight. In step 2 if I disconnect the screen cable there is no backlight or sound. I understand then that the damage is in the main? I notice very high heating in the processor/memory area under the black metal plate. A greeting and thanks for your channel that is magnificent
My tv’s main board is bad, I couldn’t find a replacement on any online shop.. wondering what I can do, it’s a high end tv and couldn’t throw it away.. please advise
o processador esquenta mesmo com esse curto , não era processador amigo , todo curdo nessa linha o processador vai esquentar mas nao eh ele o culpado nesse caso , esse tipo de placa samsung todo curto o processador vai esquentar .
I have a Led tv similar. This tv don't works when motherboard cable is connected with power supply neither standbh led lights up. When i get the cable out, leds turns on (lit). I make some tests like you and i find 3 coils shorted, some caps around processor and far from processor and pin 8 of one bios is shorted also. The other bios is good. Nothing heats. I did use assymetric power to find short. But nothing heats. Is it processor shorted ?
I disconnected motherboard from screen mre the 1 time and don't get standby light. Try turns on it with IR control and click in power button and the stby light don't lit (i maintain only power cable and power button cable). I put my multimeter in the power connector, specifically in ground pin and Led standby pin, no voltage.
When i power on my Samsung tv I get no picture and the red light flashes and I hear a squeaking noise from centre of the motherboard. Ive replaced the mother board but problem still persists. I did manage to get it working by a combination of disconnecting and reconnecting the main power and the cable on the motherside of the board. Needless to say im a complete novice at all this. lol.

Did you end up replacing main board? Or processor? Just curious.

disconnect the main board from the screen to see if you get standby light if yes could be bad screen if no for sure it is bad main board
