Seiki SE39UY04 Red standby light, not powering on

Re: Seiki SE39UY04 Red standby light, not powering on

I'm not sure if it would disappear before the TV went out because I got it second hand already broken, but I know that it doesn't now. I think the LED should be blue when its working properly also.

If the LED's are bad will I be able to tell with a flashlight test? And if they are bad is it worth trying to fix at all?

So before the TV went out, does the RED LED go off when the power switch is activated? You try both boards but this LED backlights TV do have lots of problem with LEDs going bad.

We will wait for good clear pictures, you need to check and find out if the main board is sending the PS-ON, THE BL-ON to the power supply board or not.

I should be able to post some later today, but in the mean time theoretically would replacing the main board AND the power supply board be a safe fix for it if the problem is the main board is not sending power to the backlights and PS-ON?

So I have a Seiki SE39UY04, and when I plug it into the wall the red standby light on the front comes on, but the power button on the TV doesn't do anything. I have opened up the back and none of the capacitors look bulged or necessarily bad. I really don't want to throw this TV in the garbage but I'm not sure how to fix it. Should I replace the main board or power supply board and hope it works?

I can take pictures of the boards later when I'm at home, but nothing seems burnt out or in the wrong spot on the boards.
