If control board is shutting down it won't send signal to either so no heat will be produced, also, if the panel is not lit, no heat either as no substantial current is being pumped into it.

So are you saying that the Z-sus is shutting down the control board or is it possible the control board is faulty as well?

I suspect the control board is detecting a fault in either Y- or Z-sustain and shutting the sustain process down.

Re: LG 50PQ30 Heatsinks

ok im about to give up on this thing. I have replaced the y and z sustain and also the control board. The control board now has a light on it blinking but still no picture. Also where before i was getting actually sound out of it, it is no a static sound and i tried changing the input to no avail. Would anybody have a idea on what it could be? This is really frustrating but i do not like anything defeating me lol

I have one quick question though. When i removed the bad board the upper board would show a picture but it has vertical red and black lines. Is that normal when the other one is removed?
