My 5 year old Mitsubishi WS-55819 projection TV has a power problem.
When I press the power button it turns on for about 2 seconds and then turns itself off. The picture doesn't come onto the screen as the power cuts off so quickly.
I opened the back and there is a small black diode type thing (possibly a relay) on the middle PC board towards the back that clicks when it turns on and off.
Someone suggested a leak from the 3 bulbs could be a cause but I cannot see any leaking substances anywhere.
Does anyone have a suggestion to figure out what's wrong?
I don't have electrical test equipment for troubleshooting.

Re: mitsubishi ws-55819 power problem
Ok let's levelset as is said in the business world today. it looks like you have an overcurrent protection problem which means that the tv set has a component that is causing excessive current to be drawn. Now this can be caused by a component withc has become "leaky" (by leaky this means the inability to prevent the flow of electrons as related to dc voltage). Your last statement is the reason I am replying how I am. Since you don't have equipment your only option is to take this set to a TV repair shop and have it repaired. I have given you a possible cause a component in the HV section that may have gone bad, but without substantial data as to the voltage levels and signal appearances, one can only guess.
I hope this helps and you find what you are looking for.

um . that model doesn't have a reset button . but if no lights on front of the set even blink when you press the power button on the front or on the remote .then suspect front panel buttons ,with that model.
No, that'll do it. Once you've changed em you'll know right away if somethin isn't right. But take faith and fire that puppy up. If the pix is good you did good. If something is amiss. I'd be happy to walk you through it. My money is on you though.
Code 22 indicates that your set is in shut down due to what is called Short Protect. The most likely cause is the Converge Ic's drawing too much current and opening one or 2 fuses. Normal repair cost varies by area and servicer. Expect 250 to 350 plus the service call. I normally do this on site.
