Thanks to all you guys and the great tips you gave me. I cant wait to roll this set out again from the wall so I can start pulling out cards and cleaning up the contacts. I will have a look at all the grounds and solder too. I probably should look at all the caps again as I take the cards out to get a better look at them - just wish I had an ESR meter to do a better job of checking these caps out. I forgot to mention in my original post that when the set first powers up the picture and color is very good but within 20 seconds or so, it goes bad. So if heat creates more resistance that might mean I have a leaking cap on the board or a slot pin is pulling away from its socket and not making good contact - we used to call this condition a dirty open when I was a tech at AT&T. It would not surprise me with all the jolts and shocks this cabinet took on the journey to my house. Hopefully I can do this later today or tomorrow and I will post again.
