I have a problem with the above mentioned TV. It has no standby light and does not turn on. There's no visual damage on the power supply panel, the fuse is ok.
When I unplug the mainboard the PS_ON/OFF pin produces 3.3V and the backlight turns on.
What could be the problem?
Exactly the same problem. TV is UE50F6470
I was in service menu, then the menu froze. after few minuter I disconnected the power of the TV.
After that, no standby light and no any response to buttons from the back of TV or remote control.
I am attaching the content of IC901, Atmel 24C512
The only present voltage from the PSU is A5V
The hardware buttons are getting 5 and 3.3V,
Any solution how to power on the TV?
Shall I try to send PSU ON signal manually in order to power on PSU and power the main board?
