    I am also having the same problem with a Mitsubishi VS-50705 RPTV. It started out by shutting down after about 1/2 hr of operating and now clicks off as soon as you release the button. I get fault code 22 from the front LED and I've researched issues on coolant leaks onto the power board. The TV had a coolant leak around Sept 2007, was repaired, and has been operating great ever since. No coolant is visible on the PCB at this time. Since I was not the owner of the TV at the time of the first leak, I'm just looking for a place to start and some schematics

    Unable to locat a service manual. But check the horizonta output transistor. Its located near the flyback on a large heatsink, also check the low voltage regulators also located on a heatsink but those heat sinks are smaller. Hope this helps I will keep searching for a manual.

I had this exact problem on my TV, everything said it was the power board. It wasnt, luckily i was able to return that board. It was the YSUS board.

I should have done this this first but this is how i verified the old power board was good. Unplug TV, take the cover off and disconnect the wire harness going to the YSUS, plug TV in and turn on. If led stay blue its the YSUS.

Hello melanie Hi, in my experience as a TV technician, that would usually be a shorted part, the horizontal output transistor, that part powers the HIGH Voltage section. Very Lethal, the power supply detects this bad part which in turn makes the unit go in standby so as not to damage the TV much further. mMy advice is go seek a tv tech to repair the part.

It wont turn on anymore. it fires then instantly shuts off, doesnt even flash screen. standby lights still flash and its trying to turn on, just cant get on. you can hear the on sound and then the tv...

Depending on the age of your tv, if you hear a rapid clicking, it seems like your ballast is starting to turn on your tv but it's not able to. (1) Check your lamp, (2) reset the lamp timer, (3) make sure the cover panel is all the way. the positioning sensor might not be detecting the cover all the way in.
Personally I think you're experiencing a ballast problem.
