All 47uf, all 220 uf, all 100uf, probably most if not all of the 10uf, and 4.7 uf. it is a pain. they are all surface mount caps and very close to feed thru's. I repair these for a living and have specialized de-soldering equipment just for these. since you have it apart why not check out www.tv-techs.com. it might be easier.

There are small surface mounted capacitors on the dm Board and the fmt board that have gone bad. They need to be replaced. Most tv techs will charge about $400 to do this.

Most likely the issue is bad capacitors. You need to check for bad 1000uf 16v caps on the dm board and the fmt board. Be sure to checked surface mount fuses on DM and FMT board after you replace the capacitors.

Not to easy of a job due to how much dis-assembly needs to be done. Instructions can be found online on how to do this.

Blinking light with no picture or sound


If you have a green blinking light,
Most likely issue is with bad capacitors on the DM an FMT boards.

1) Look for bad 1000uf 16v caps on the dm board and the fmt board.

2) checked surface mount fuses (small white boxes) on DM and FMT board

Look carefully for other bad capacitors in the general area.

Start here and let me know the results.

Note, there is a lot of disassembly to get to these boards. Not a fun project.

Green diagonal lines


the FMT caps have most likely failed. You can get the V26 FMT repair kit from www.tvrepairworld.com which also contains instructions.

Blinking Green light after Capacitor kit replacement WD-62725


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,
Dan

Blue Flickering Screen - Which Repair Kit?


yes they provide a free service manual with their kits. the symptom of the blue screen could either be the signal or the FMT as they can both cause those symptoms, My professional guess would be the signal board as the FMT will cause distortion lines across the screen with no picture.

Blue screen with flickering horizontal lines


Sounds like the 1000uf capacitors on the FMT board need replacing. This is a common symptom with that chassis. There are three 1000uf caps that fail on that PC Board
