Samsung PS-50q97HD Led flashes and stays on, but no picture

<< < (2/2)

gangerlv:
Ok, replaced one buffer ic and a fet. Got picture, 1/5 of screen and not very clear.
Any thoughts?
And screen seems to be split right in the middle, one side darker than other.

mzone:
the buffers are still bad. you will need a new top & bottom buffer mate as they are common to failing. these are what caused the y-sus to blow.

Tellyfix:
If the y-sus has been checked and is OK just replace the upper y-buffer and all will be ok. done several of these sets and the panel is usually ok. just inspect it using an illuminated magnifying glass carefully, looking for distinctive burnt out pixels....

gangerlv:
Damn you, i bought lower y buffer - it was cheaper. Will put just lower one in and test the set.
