Question about Mitsubishi WD-62725 62" Rear Projection HDTV-Ready Television
I have a 2004 Mits WD-62725. First the red-light came on, so I got a new lamp. Didn't fix it. So I put another new lamp, same thing.
The TV would start the blinking green light, then turn off. Then I turn the TV on, after 5 minutes of no picture, the light turns red again.
Self diagnosis before the light would turn red would give a 12 (no issues).. But once the red light would come on I was getting code 34 (lamp failure). However I have 2 brand new lamps.
So I did some research and found out I probably needed the capictor kit. I replaced them all except the (2) 3300uf 16v (biggest in the kit), becuase the replacement caps are phystically too big to fit on the board.
I'm going to hit up Radio Shack to see if I can get some with a smaller foot print but same specs.
However the (2) 2200uf 10v caps had the puffy top look, and they were replaced with (2) 2200uf 16v caps.
I put the TV back together and now all I get is the constant blinking light for hours.
How likely is it that the 3300uf caps are bad? Should I just replace ALL of the caps on the board?? I just realized Radio shack has all of these caps for less than $30 total....
Any chance it could be the ballast?
I just repaired two Mit WD-62725 sets in the last two weeks.
The first one had bad caps on the power board and the FMT board. The scond one had bad caps on four out of the five boards.
Also, on the FMT board, there was a blown surface-mount fuse.
I advise checking all of the boards for bad caps. If you fine a bad 1000uf cap, replace all of the 1000uf's on the board.
Hop this helps,

Testimonial: "Great comments. Quick to respond!"
It is most likely not the ballast, it won't cause the constant blinking light, you can try changing the caps, but we have been having to send the whole chassis in to Mitsubishi for them to rebuild even after changing all the caps, but I would give it a shot of changing the caps first. Good luck.
