When I turn tv on the green light comes on for a couple seconds then I hear a click and it turns off. I never see a picture. I suspect that there may have been a power surge. I lost my DSL modem power supply in the same room during the same time frame.

    Thanks Vince. I am not an electronics person. This sounds like a repair that may require some professional help with? Is it cost effective and possible to just replace the power supply? I may be able to handle that.
    Thanks,

Hi sir good day here is my solution, since your unit is turn on then turn off you need to check first the power supply look for shorted component at the same time capacitors with bulging on top to its casing it cause a voltage drop. replaced it with the same value a panasonic FM or FC series much better with low ESR. you can find replacement parts at www.digikey.com. now check also the ballast board for the lamp which cause the clicking if their is a bad component here the board will turn off then their is no picture.hope this may help thanks for consulting us feel free to ask further question.

    thanks for the response yes it needs a thorough trouble shooting since the problem is not simple only like just replacing a fuse.almost parts inside are dealing with high voltage and before replacing parts or board a thorough check up first needs to be done which need a will trained people to fix. however at least you have an idea what to expect when you decide to hire for somebody to fix the problem. thanks again for consulting us.

I have a 56" samsung rear projection tv that won't turn on. the red standby light is lit and when i push the power i hear two clicks and the green timer light flashes quickly then the green led stays lit...

I suspect you probably have a bad LED assembly. It could be either the red, green or blue that is bad and give you the same symptom. The problem is locating parts for it as it looks like the light engine is no longer available. I would have a technician look at the TV to verify this and what parts are needed for repair.

When turning on the TV the green light on the front does not come on. You hear a click and then about ten seconds later you hear another click but the tv never comes on.

What light do you get, green blinking, red blinking, yellow steady light or yellow blinking light. The led lights will tell what is wrong with your tv.

Mitshubishi WS-73907 won't stay on

I suspect you may have a short in the horizontal deflection circuits or High Voltage transformer. If the set had a "great" picture, it may be worth fixing providing you aren't planning to upgrade to a HDTV anytime soon, otherwise I would use this excuse to start looking for a new set. Worst case I can envision with this set would be one of the picture tubes having a Short, keeping the set from turning on. That would make it unreparable.

Flashing Standby/Stero light and No picture.

How good is your picture when it did come ? Is it as good as it once was ? Or is it alittle washed out. If it is washed out the picture tube is weak . Sometimes turning up the screen control alittle would solve problem but if you turn it up too much you would have faint white line running diagonally. Now if you think the picture was good before you this problem video circuit would be your suspect . Jungle IC or something in the RGB circuits . Good luck
