Dm board mit wd52525

I looked at replacing the P13119 capacitor, but they didn't look bad. There were two capacitors on the power board that did look bad. The number on them was HD420. Does anyone know what these are and if they can be replaced? Where can I find them. DigiKey? Thanks

Re: dm board mit wd52525

The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.

Tv keeps turnig off

You have the V26 chassis with it's notorious problems caused from leaky capacitors. The fix for this is a multitude of capacitors replaced on the DM board, FMT board and the power supply. The right thing to do is to call Mits consumer relations @ 1-800-332-2119 with model, serial and date of purchase and they should be willing to make a concession for discount on a new Mits DLP. That's your best bet. This TV will continue to haunt you otherwise.

Want to replace caps which board is the DM board?

Once you take the shield assembly off, you will see a board, I believe it is the DM Board board. There are four Capacitors grouped together probably rated at 35v 1000 mfd, 105 degree. They should be replaced with 35v 680mfd,105 degree Capacitors. Now once that is done, there is another board under that one. This is the Format Board. It also has 4 Capacitors that should also be replaced. They are the same value as the first Board and should be replaced with the same 35v 680mfd, 105 degree Capacitors.
Please note the Flex connectors at the bottom of the DM and Format Boards. They may not be available from Mitsubishi any more so be gentle with them and make sure the are installed properly when reinstalling the Boards back into the chassis. There is one other Board you should look at. The Power Supply Board is the board on the back of the chassis and also has a number of Capacitors that fail. Most all of the Capacitors that fail through out this chassis will have bulging tops. So any you see bulging, you should replace whether they are on the DM, Format , or Power Supply.
I hope this helps,

The first generation mitsubishi V26 chassis which is what your model is has a bad habit of failing capacitors. The steady blinking green power light is related to the DM not completeing the boot up sequence.

Its very inexspensive and will usually repair that issue. Its listed under the repair kit category.

Picture flutters and distorted

Capacitors going bad on your DM or FMT board. Very difficult to replace, but Mits does a rebuild on the chassis. I recommend talking to your Mits service center and getting the rebuild done.

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.

Won't turn on

Do a search and you will find a lot of us that had the same problem. The issue is probably 4 bad capacitors on the DM board. The parts to fix it cost about $2.
There used to be a "how-to" detailing how to do this repair, but I can't find it anymore.
These are the capacitors you need..
part number - P13119-N
get them here..

Mitsubishi WS55513 ---Flashing Green LEDs...and now NO POWER.. the entire board / chassis out of the TV shell. Going to start checking individual components, starting with the mail power supply...

start by pulling the DM board (looking from the back it is standing upright on the left side in a metal chassis) and you'll probably find 4 bad capacitors (bulging on the tops is a good indication, If i remember correctly they are near the top right corner)
you can buy replacements here..

Fixed mine this way several months ago..still working like new.

Good luck
