Plasma sound but no picture Can't Post

I have a 42" Samsung plasma Model PS42B430P2W made in 2009.I have sound but no picture, all the voltages read right from the y/x boards also going to the logic board. The heat-sinks get warm on all but one on the Y-sustain board, I have a small light flashing once a second on the logic board. I have looked at the screen in a dark room to see if there is any sign of life but none at all. Have looked at all the caps and they all look like new as do all the PCB's in the TV. I have run the TV with sound only for an hour without it shutting down.Have you any ideas what I could try next thanks.

Re: [Horace0011] Plasma sound but no picture [In reply to] Can't Post

This is an update on my problem, I have replaced the Y-sustain board and now I have a picture but it keeps going off and all I have is a lot of colour pixels then a perfect picture for a couple of minutes then back to pixels again. The Ve reading on the Y-board should read 0 but I get a reading of 90, does this mean a setting is wrong? If anyone has any ideas please let me know. Thanks
