My grandfather passed away and left me a WS-55711. The picture screen is amazing, but then suddenly the unit died. A service tech came to the house and after diagnosis, told me (like so many other people) I needed a new DM board.

In the past I was a amateur radio enthusiast, so I have worked on Transmitter/ Receivers. However this was a while back. If I can save money for xmas, can anybody tell me where to buy a DM board and offer the instructions how to complete the task. Do I need a service manual to understand the circuitry for this DM board.

Thank you

Lost power early this morning and now the green light is flashing - reset does not help No picture and no sound


Thats a very common problem caused by weak capacitors on the DM board. When they drain they cant recharge when power is restored. The Mitsubishi repair kit called the WS48511 - WS55511 DM repair kit from www.tvrepairworld.com is the kit that will usually repair the issue. The kit contains the Capacitors and the CD with repair instructions.

Tip

Mitsubishi won't turn on and has flashing power/timer light.


All Mitsubishi WS-XXXXX model projection TVs have defective capacitors on two different boards which will fail after about 5 or 6 years. Getting parts is the difficult problem.

The two boards are the power supply board and the DM board. Mitsubishi is aware of the problem and sometimes can be talked into offering money to help fix or purchase a new unit. I have direct evidence of customers getting $500.00 towards a new unit to settle the issue. Of course this requires an agressive posture. But let's face it, they made the defective units, they sold them, they refused to admit that they made a mistake, so why shouldn't they pay?

This model has a documented problem of electrolytic capacitor failures on the DM board and power supply board. There are no replacement boards available but there is a repair kit for each board available at http://www.tvrepairworld.com/mitsubishi_repair_kits which has the usual parts that go bad and generally will repair the unit. The cost is $36.00 US per board. It is not an easy repair but tvrepairworld has very good installation instructions as well as videos you can watch on their web site.
TV Repair World has just added a new repair kit which has the parts for both the DM and power boards for $61.00 and shipping. For my money that is the kit to get. The kits come with excellent instructions and pictures as well as online help.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.
