I have a Mitsubishi ws-55511 TV, And for over a week now i can't find whats wrong with it, The green light flashes for about a minute after you unplug it or press the rest button on the front, but after that... the power button on the front or on the TV's remote will not turn the TV on. I know its getting power cause when you unplug it from the back you can hear the TV powering off. But I still have no picture, no sound, no nothing, What can i do? The TV repair guy quoted 95+ just to come take a look at it thats not including parts or labor.....
There are lots of problems that can cause this problem you are having with your Mitsubisi TV set. You could have a coolent leak from one of the picture tubes, there could be bad capacitors in the set and if this set has a DM board, there are bad capacitors inside there as well. The convergence IC(s) could have failed and shorted out the plus and minus 24 volt power supply. A set like this you really need to get a tech who is experienced with Mitsubishi, as this set is 5 or 6 years old already and if they want to replace a board, it most likely will not be worth the repair price. A good Mitsubishi tech will repair a board down to componet level unless it is a digital board and not field serviceable, or their is a major blowout and the board is damaged beyound repair. Good Luck and let us know what you find out about this TV set.
