My buddy has a Panasonic PT-47WX49 that has a series of lines and distortion on the screen when it is first started up.  It started out as being just for the first couple of minutes, but it is continually getting worse.  It now takes about 15 minutes for the lines to disappear and the picture to look normal.  Searches on Google indicate that there may be some "dry" capacitors.  Does anyone have any information on this?  (which board, which capacitors, etc?)  (Or what else it might be?)  It doesn't look like a "typical convergence problem.&qu

Hi, Our VS-60705 is about 9 years old and has been getting horizontal lines until warmup. It has been gradually getting worse. I read another post from a couple of years ago and he had ezact same problem. He said there were two capacitors that seemed to be causing the problem. Well I put a heat gun to each of them and I could get it to fail or get better by adding heat or freezing. There are 2 capacitors right next to each other. The one that I found to be succeptible to heat and cold was C 957.
