Hey guys I have one here that should be simple, just looking for a quick answer on what you guys think.
I got this TV the other day, and it would power on, but randomly turn itself off, and then click the relay a few times and turn itself back on, usually with a message "an error has been detected and recovered."
Now there were also a few times where the TV would just "freeze" with a screen of a lot of vertical bands of color before doing the power cycle as mentioned earlier.
Today I try to start measuring stuff and low and behold now it won't turn on at all. Now all I get is the relay clicking on and off repeatedly. The one thing I have noticed is that if I hold the power button in after about 5 seconds the relay will turn on without turning off again until I let go of the POWER button. When I do this, the main cap will go from 400v to about 170v. Also, when I don't touch anything the main cap is usually going from 400-350v synchronous to the relay clicking.
Now I'm pretty sure the problem lies within the power board, however the fact that the screen froze with the weird vertical lines of color when it was working still puts me a little on edge on if it could be an A board problem.
Pics of both below.
Any suggestions?
