Mitsubishi power board pcb post
Good day, steve sc;
The DM board is normanlly on the left side TV looking from the back. It has a shield around it, remove. The caps are big and black, they look the replacements(only ones on board). Here's what says about this issue:
If the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). (LED does not stop blinking after plug in) On the DM
Good Luck, big IRISH. ps hope this helpful!
PCB (part # 934C116002) 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).
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.
