Our 55" Mitsubishi CRT projection TV, model WS-55315, no longer turns on after the power flickered during hurricane/tropical storm Sandy. It was off at the time and I don't think there was a surge - everything else in the house, including my computer which was on, is fine and the TV is surge projected. I walked downstairs to find the TV off with no power light (as normal), but it would not turn on with the remote or the button on the front. I unplugged it and then plugged it back in which caused the power light on the TV to light up, but there is no picture or sound. It does not respond to any input so pressing the power button won't turn the power light off and I can't read any codes. I pulled the access panels and the tubes are not lighting up at all nor do I hear a "click" or any sign of the TV coming on. All the fuses (normal & the numerous pico fuses tested in circuit) tested fine. I can't find any sign of bulging caps or burnt resistors/ICs/etc. Any ideas? I have a multimeter and an old analog oscilloscope if that's helpful.

Thanks!

These sets tended to have problems with the front panel control switches oxidizing, IIRC. Try repeatedly pressing all of the buttons quickly with the set unplugged. Sometimes that will break up the oxide on the switches enough to stop it from conducting, which ties up the micro. You may also be able to unplug the control panel and try just using the remote to see if this is the problem.

Thanks. I'll give that a try tonight. Do you know if the power led will go out with the panel disconnected? I thought I unplugged it earlier, but the LED remained lit. There's a bundle of wires running from the approximate location of the bezel to inside the TV with an inline connector that I disconnected, but it didn't seem to do anything. I did this after the TV was already plugged in though.
