Wd52525 capacitor replacement

Replaced the capacitors on the dm board that was suggested as well as the other two circuit boards the clusters of four. The (2) 3300 10v on the power supply board were also replaced. The TV turned on and still have the same problem, the lighting is very dim. What is my next step? Could it be my ballast, light engine? The TV does'nt turn off and no light comes on indicating any problem. Cleaned lenses and mirrors replaced lamp. Hope you can help. Thanks

There are 2 mirrors in this set. the small mirror located in front of the lense is the most important. it collects dust and grime.clean it thoroughly.not only will this dull your picture it can also cause small blotches in your pix usually noticed on light colored scenes.

We lost power the other night. Now I have a continuous green blinking light and it won't turn on. I have tried everything the manual says.


Try Going To The Mitsubishi Web Site. Downloading The Mitsubishi Service Manuals If You Don't Already Have It. It Will recommend The parts You Need To ordering. Circuit board photos are also shown which provide a visual reference during the repair process.

If you decide to have a service technician do the repair, insist that the "DM" module is removed from the TV and ONLY the four 1000uF, 16V Capacitors (Caps) located on the DM Module are replaced. MOST techincians will INSIST on replacing the entire DM Module and not simply the capacitors. The cost is about $200 for a technician to replace the capacitors and $1000 for replacement of the DM Module. As you will read below, doing the repair yourself will cost less than $4.00 for the 4 Caps.

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 Capacitors on the DM board need replaceing. The V26 DM repair kit from www.tvrepairworld.com will usually repair that issue. The kit contains the capacitors and the CD with instructions.

Green power light keeps blinking


hi friend,
Repairing It Yourself
If you decide to repair the TV yourself, I recommend that you obtain a copy of the repair manual for your Mitsubishi TV from the Techlore website by going to Mitsubishi Service Manual. It will provide some direction, however it is technically written and may be difficult for the NOVICE to understand. If you are unable to locate the the service manual for your specific Model at the above Techlore link, you may need to purchase the service manual online at ServiceManuals.net.
If you decide to have a service technician do the repair, insist that the "DM" module is removed from the TV and ONLY the four 1000uF, 16V Capacitors (Caps) located on the DM Module are replaced. MOST techincians will INSIST on replacing the entire DM Module and not simply the capacitors. The cost is about $200 for a technician to replace the capacitors and $1000 for replacement of the DM Module. As you will read below, doing the repair yourself will cost less than $4.00 for the 4 Caps.
A Few "Cautions"
  1. Keep yourself "grounded" when working with the circuit board. Static electricity will destroy electronic components.
  2. When replacing the Capacitors, press them "down" onto the circuit board as far as they will go, hold them down, solder into place and clip the excess terminal lengths flush with solder. Only by doing this will the metal shield (little silver box) slide down and over the circuit board during re-assembly. There is not a lot of clearance when doing this, as the 105C Capacitors are slightly longer that the originals. With minimal effort everything does fit back together.
  3. Use ONLY 105º C capacitors with a voltage rating of 35 V.
  4. Re-insert the DM circuit board into the Mother board; press virmly and ensure a proper seat of the DM board. Next, slide the metal case down and over the DM circuit board. Refer to my "Lesson Learned."
Basic Troubleshooting
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.
  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.
  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.
  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.
  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.
  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.
Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:
  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

I have a Mitsubishi WD-62725 with the ''blinking green light of death.'' I got this T.V. for free so I figured might as well try to repair it myself (and can I just say did Mitsubishi really have to make...


It's definitely the one causing the problem but I suggest you also replace or resolder the 4 capacitors on the DM board to make the job at once. Just make a note on the polarity markings of the capacitors and the board. If there's no indicated polarity markings on the board then nevermind. Here's what you need to do the job:
  1. Soldering iron
  2. Desoldering pump
  3. Soldering lead
Steps:
  1. Heat up the soldering iron
  2. Melt the lead on the board with the soldering iron and use the desoldering pump to remove it and loosen the terminals of the capacitor.
  3. Remove and replace the capacitors one at a time to avoid confusion.
  4. Make sure to make a good solder. A good solder is volcano-shaped.
  5. Cut any excess lead terminals.
  6. Make sure there's no stray leads that might cause short circuit on the board.
  7. Check the terminals of the newly installed capacitors for any short circuit.
Tip:
The board experiences vibrations during the operation of the unit. These vibrations can result to broken solders as the time passes by. Before re-installing the board, check it for any loose or broken solders and resolder as a preventive measure. A magnifier will surely help.

I have a 37inch insignia


Some people I contacted said it has faulty capacitors that need to be relaced. Available at radio shack.
Most likely causes in order:
  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.


To replace capacitors:
  1. Keep yourself "grounded" when working with the circuit board. Static electricity will destroy electronic components.

  2. When replacing the Capacitors, press them "down" onto the circuit board as far as they will go, hold them down, solder into place and clip the excess terminal lengths flush with solder. Only by doing this will the metal shield (little silver box) slide down and over the circuit board during re-assembly.

  4. Re-insert the DM circuit board into the Mother board; press virmly and ensure a proper seat of the DM board. Next, slide the metal case down and over the DM circuit board.

It sounds like the capacitors inside the DM board is going bad or there is a problem with the FMT or formatter board. The DM repair will require replacement of four capacitors and if not done right away, the problem will get worse and burn out the IC's inside the DM and the DM will cost about 1000 bucks to replace! Good luck

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.
