67" rear projection Mitsubishi....

On Left hand side of chassis look on power supply board for bad capacitors they will be swollen or puffed up on top.

need replaice capacitors in vertical output cir.

This model series had a odd problem that caused this. It was the Hoizonal wire connctors for the yoke. If my memory serves me right, the Yoke wire harness went from Yoke to Yoke and plugged in at the casing of each yoke. What I found is the solder connection on the small board of each Yoke was intermitent. Please be careful if you choose to tackle this. It is in a HV Area.
Hope this helps,

it could be the bulb the lights u are seeing should be green not red.

LAMP BULB IS BLOWN

Good Day;

It sounds like your lamp is getting weak, replace lamp. Good Luck, big IRISH.

tv worked great, turned it off one day and back on the next and the on light would not come on nor would the tv work, rear projection 52 inch rca

Good Day;
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.
