Checkerboard screen on Mitsubishi wd-52525 tv

Good Day;

Replace all mentioned, if they look bad or not.

Tile or block pattern . Check D8F00 and D8F01 part # 264P828010, also check C8F26 and C8F29 part # 141P148000 (1 uFD, 25 V) on the FMT PCB (part # 930B924002).

Trust me, Good Luck , big IRISH. Board may not be avail.

Good Day, xx07xx;
Not sure what your exact problem is but; Check D8F00 and D8F01 part # 264P828010, also check C8F26 and C8F29 part # 141P148000 (1 uFD, 25 V) on the FMT PCB (part # 930B924002). The bulging cap replace with 680ufd (same voltage), if they are 1,000ufd's. To order try 1-800-458-6053 B&D Enterprises.
Good Luck, big IRISH.

Good Day;

Replace all caps that are swollen, but resolve your checker pattern:

1. Tile or block pattern replace D8F00 and D8F01 part # 264P828010, also replace C8F26 and C8F29 part # 141P148000 (1 uFD, 25 V) on the FMT PCB (part # 930B924002).

The diodes have a stripe (line) that is the cathode, at one end of the device, the board will reflect that line. Good Luck, big IRISH. PS ; De solder as best as you can, glue is under part, heat one end, while prying up, heat other end. It will come off with moderate to mid high heat.

Good question, but I'm not THE FAMOUS "TECHMAN" but I will try to help anyway. 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. PS; I hope this helpful.

Good Day, gary;
It sounds like the TV has a bad formatter board. This board is not available from the factory, it must be repaired. 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). Remember FMT PCB is not available. Good Luck, Big Irish.

Good Day, Joe;
Suspect the formatter board, FMT PCB, it is not available through the factory though, it must be repaired.
On the FMT check D8F00 and D8F01 part # 264P828010, also check C8F26 and C8F29 part # 141P148000 (1 uFD, 25 V) on the FMT PCB (part # 930B924002). This Avery common problem.
Good Luck, Big Irish.

Good Day,

You all;

This problem is on the 'formatter' board. This is NLA, so it has to repaired, theses parts are surface mounted

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). I hope this helpful and not too late. Good luck, big IRISH.
