Question about Projection Televisions

Bad caps Big Irish, can you please explain why you would replace the 1000uf caps on the WD52525 DM pcb with 680uf? I saw the below advice you provided and was wondering if this was a factory fix. (check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).

Flashing power light tv wont come on mitsubishi 1080


If the tv has the continuous flashing led, you have a DM board problem. It is likely bad capacitors in the DM module.. there are 4 of them 1000uf caps that will go bad. They will get a bulging top on them when they go bad. . Mits recommends replacing them with 680uf caps with a comprable or higher voltage rating. The DM module in on the left side of the set (viewed from the back) and is somewhat difficult to remove.

Timer light blinking green/tv won't turn on


The DM moduel is bad. You can fix it by replacing 4 filter caps on the DM moduel. Do not replace them with the same type that is in there. You need to replace them with 680u 16v electrolitic caps. They are easy to find. Pull out the DM board, they are at the corner of the board and the tops of the caps are bubbled out a little.

It is not an easy job, it will take some time but since you have it apart there is another problem that will accure so might as well do this too:
Tile or block pattern with no video or OSD. Check D8F00 and D8F01 part # 264P828010, also check C8F26 and C8F29 part # 141P148000 (1 uFD, 25 V) on the FMT PCB (part # 930B924002).
All the parts have location numbers like C8F29 that will tell you what and where these parts are.
Good luck, big IRISH. PS; I hope this helpful.
