I was recently given a WS-55511 by a friend because it wouldn't power on.  After reading many threads in this forum, I went ahead and replaced the 7 capacitors on the DM board.  After getting everything back together, the TV powers on and has a perfect picture for anywhere between 5-20 minutes, then it reboots itself.  After the LED stops flashing, I can turn the TV back on and it works fine for another 5 minutes or so, and the process repeats.  The only code I can get from the LED is code 12 (no trouble).  Any suggestions as to what else could be causing this?&nbsp
