Looking for some answers. I have a xx725 with mit rebuilt chassis 2 years ago and now a new problem with a burnt smelling while tv is on, no flashing lights or codes. Found the lamp connections melted to the ballast power cable. Could not just pull the lamp out to check it, had open the tv back and gently work it from the lamp power cable from the ballast and found the burnt smell. The good news the house did not burn down. What would cause this ? Tv was still working with no codes and it will not go back together with these fried connections. Any Ideas ?
