    lg 50pw350 HELP PLEASE!

    OK here is the issue and if anything please point me to some threads. i tried a search but couldnt come up with my tv.

    what happened...tv shut itself off, turned back on and was on for about an hour. same thing happened turn back on lasted about 45 mins. so on and so forth until now it just turns on and goes right back to standby.

    i got online and seen it might be the power supply board so i ordered one and that didnt fix it. so i found where i could kind of troubleshoot it. i disconnected the zsus and had no picture but had audio, then i tried the ysus, same thing, connected everything back and disconnected the zbuffer. problem is the power goes from power supply to ysus then zsus, so i cant isolate either board. any steps i can take to see which board is bad before i buy both and only need one?

    all help would be much appreciated, let me know if more info is needed, also links to other threads or even what terms i need to search for would help. Thanks!!!

    You need to check the Pson and Vs on signals that the mainboard generates see if it goes when it shuts off. Doubt its a Sus fault as if it was Tv wouldnt give clear image.

      Even if when I unplugged the sus boards the audio worked fine, and when i plugged tem back in it would turn off almost right away?

        This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

        I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

        I am comparing them to a brand new one that I installed

        The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

        I going to let it run for several days before I remount back on the wall next to the...
