Re: Samsung un55b8500 won't turn on constant click
So after some further reading disconnecting the main board and having no backlight points to the power supply. I have inspected all the caps and see no bulging. I have also inspected all solders and see no cold solders. What is my next step to diagnosing the power supply?

Re: Samsung un55b8500 won't turn on constant click
There is no backlight when main board is disconnected from psu. I did some quick reading on the bga. This issue seems to be similar to what used to happen to old Xbox 360s. Just to clarify the fix seems to be to heat it up so the chip can reseat. Is that what I should do?

Re: Samsung un55b8500 won't turn on constant click
Side note when I plugged in the tv this morning it worked for about 5 min. when main board is disconnected there does not seem to be any backlight. It is hard to tell. But my panel is a full array backlighting. Even when it was working I could only see backlighting behind the part of the panel being used to light up the " no signal" that was being displayed on the tv. Is the backlight supposed to be on if the main board is disconnected?

Samsung un55b8500 won't turn on constant click

After waiting for a while (tv clicked the whole time) the tv would come back on and start working again. The frequency between this happening has gotten shorter and shorter until finally my tv has started clicking and will not turn back on. Also during this time my tv would sometime switch inputs on its own.
This actually happened to me about 6 months after I bought the tv and it was...Last edited by Hockeyjock; 10-25-2016, 10:50 PM.
