Mitsubishi WD-55513 ( HDTV 1080 ) Still flashing after DM board repair

Thank you for your great guide to repairing the DM board. My aunts Mitsubishi WD-55513 ( HDTV 1080 ) was doing the flashing light ( green led / timer ) non stop, and after reviewing your post I was certain this would correct the problem. I did exactly what you said, even got the replacement Radial Caps from Digikey, as the ones on her DM were indeed bad. ( bulged tops, and uF'ed questionable ) Anyhow, put it all back nice and neat, and the same problem as before. Any tips or ideas as to where we might look next? I feel with your vast knowledge of these systems it must be an oversight on my part. I would greatly appreciate any help or where I might try next. Thank you in advance!

There is probably a voltage missing on the secondary of the switch mode power supply . check for pico fuses.(the kind that solder in). Usually one other will open up and the same results will will appear because the set has protected itself from any more damage by a fusible resistor or pico fuse. I am impressed by your throughness in sticking with the solution of this problem. Make sure the set in unplugged and test all secondary pico fuses and current limiting resistors. This 1sv where you will probably find your problem. Everything you have done so far is mint. Scrivitron.

Mitsubishi hdtv1080 won't turn on. green timer light flashing

could be a lot of things really. when you replace the bulb, there is a switch that will prevent the tv from turning on if the cover isn't sitting correctly, by moving it that might have shifted so it would blink, but not turn on. if not, well get it serviced, sorry

You can easily fix the DM Board

It is fixable for about $10

That is an extremely common problem with Mitsubishi tvs old and new. It can be fixed easily and cheaply for those willing to use their hands.

Refer to this guide to replace the capacitors on your DM Power Circuit Board part # 935C9860. You could also have someone else do it for you for $100

Guide for a $10 DIY repair in capacitors :

Paid Rebuild Service:

That fixes the problem most of the time.

After replacing capacitors is you still get green light try replacing the EEprom. EEprom board also known as the E2P board is part number 935C978001

Mitsubishi ws-55513 blinking power light

The infamous flashing green LED problem is usually due to a failing or faulty DM board. I purchased the PDF manual online and was able to locate and remove the components as necessary.

If you can solder, and are semi-proficient with electronics it is 4 bad capacitors on the DM board...

Otherwise there are facilities that can repair your failed board for about 275.00 or replacement of the board is between 350.00 and 500.00 buck USD.

Good Luck with your repairs....

Mitsubishi flashing light replaced capasitors that were blown tv still has flashing light

The four cap replacement in DM module repair is simplistic
and incomplete, as you found out. ALL defective DM modules
have bad SMC's ( small "top hat" caps) AKA surface-mount
capacitors that can be changed only by the most highly skilled
bench techs. We used to change out hundreds years ago in
camcorder circuit board repair.DM board repair is a much more
accessible,thus more "do-able". For more info.............T.
