I have this TV. I have changed the psu board with a new one but I still do not get standby light or any kind of response.


backlight is ok and tested with BL tester. the issue I think is on mainboard.

what should I do?

Post pictures of your circuit boards and give any voltage readings you have taken.

All the voltages ta psu are there:


12V, 24V, 3.2V ps_on,

the backlights work because they are tested by tester

The command to turn on the stb LED is given by the processor. The command for powering the t-con with 12v is given by the whole processor.

I dont get any voltages at tcon

Elaborate, "I dont get any voltages at tcon" No voltage coming in from mainboard, getting to tcon fuse, leaving tcon fuse or going to panel?

I dont get the 12V on the tcon fuse and at the lvds cable from main to tcon I dont see any voltages apart from 3.3V.
