    even if the tv works fine for about 2-3 hours and this issue only happens when it heats up like after 4 hours i would think it would be a solder connection as if it was a connector it would happen right away at the beginning at boot up no. any advice how to check these cables i had the tv for some time

    Yeah im thinking its a temperature issue i think what i am going to do is use a thermal probe probe the pcs at cold and then at hot then look for the issue once i find a real hot area i will zap it with cold spray and see if it changes i am wondering if one of the pcbs itself is going but i think its a solder joint as it is when to plasma gets hot any other suggestions let me know.

Not a solder joint. One of the two ribbon cables that feed the PDD is not seated correctly or has pulled back slightly. Believed to be caused by rough handling in shipping. This is a tedious job for the unexperienced, but can be done with patience.

    being that it hasn't done this from new, slightly less likely it's the ribbon cable, but know that this is a thermal issue. Absolutely it could be a cold or broken solder joint. Get some strong reading glasses and a flashlight. Look for gray or cracked solder. Usually shows up as a little circle at the point of the break. I am working on an LCD camera that has a ribbon issue when it warms up. In this case, the insulation is delaminating.

Check the A/V cables on the back (red, white, yellow, or in some cases, red, green, and blue) and make sure they're all plugged in correctly. If not, you may have a bad wire, or even a bad TV
