Mitsubishi ws65613 no picture or sound, blue screen only
Blue screen that has gotten worse over the past few days, I would suspect fluid on your signal board.
The three CRT's in the TV has coolant that tries to keep them cool but they have a problem with the 'glycol' leaking out of it's chamber.
Take speaker grill off, remove panel and look on the right side of opening. Look for fluid on the board, shinny substance, it's hard to see so look closely. That is the most common problem.
2&3 are the CRT's or the CRT's drive circuit.
Good Luck, Day,let me know, Big Irish.
