Question about Televison & Video

2 Answers

I have a mitsubishi 55511 television. I had a power surge and the power button shows a constant green flashing light and will not power up. I can hear a clicking in the av tuner, dm power box. I replaced the 7 DM Power supply 16 W fuses with 35 W fuses but the problem still persisted

    I have already done all that. This is a common problem with all Mitsubishi Tv's that are rear projection from that period (2003) thats why I replaced the fuses in the DM power supply but I'm not sure I got them in right because the 35 watt fuses were quite a bit larger than the 16w fuses and they were real crowded going in. I wonder of some of the sodier welds are not good.

    The fuses were not it. I am not sure how to disconnect the front pannel volume control. Do I just look for the wires and follow them to the board and disconnect? won't that also disconnect the sensor for the remote?

Did you try the self-diagnostic called error code operational check? If yes then what is the error code that you get?

Front Panel board the one that has power/CH- CH+ Vol_ Vol+ disconnected it and wait 70secs then with remote hand unit see if TV will turn on,if it comes on then you need to replace the front panel board or all of the contact switches on it.

    Im a little confused because its 7 capacitors on the DM board that you have to replace they are 1000uf 25v use 35v capacitors most of the time its 5 all in a circle on the DM board.

    Capacitors are bad if they are swollen,vented or puffed up on Top.

I recently was given a mitsubishi ws-55511 55 in tv it has the blinking green timer light that keeps flashing what might be the problem and any idea on repair cost?


First you can try pushing the reset button located on front of tv where power button is located. If that fails to correct the problem then I would suspect the DM module has failed. They are not available for replacement. Some shops rebuild them by replacing the defective capacitors with some success others might send it to a company such as PTS to be rebuilt also with some success. Repair prices will vary from 275.00 - 375.00 depending on your location

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.
