I press power button on either remote or on the tv and the green light comes on then a click is heard and tv goes off. I have tried reseting it, unplugging it, and a number of other things , but nothing helps. what do you think.
The problem is with your power supply. either you repair it or replace it.
Good Luck!
The problem is the convergence circuit, in order to fix this issue you will need to replace an entire circuit board, the cost to do this is most likely more than the tv is worth, the new LCD"s are cheap, replace it, you will not regret the decision.
If you know how, chek the horizontal output transistor for a shorted condition. If that is ok, the likely defect is the convergence circuit. Try resoldering the 2 convergence ICs (STK393-110) that are attached to a heatsink. If that fails to resolve the problem, replace the ICs. Also in the same area, check the pico fuses that have the board designation: F9A01-F9A06. If any of those measure infinity using an ohmmeter, replace them as well.

It must be hardware problem. if you tried all the solutions here and nothings work then send it to repair service. when did you bought your tv? it should have a warranty service for this.
cheers

Its ic problem check ic and another is power control swicth remove the ic and fix the new ...........
I have to chak the curcuit bord capacitor has beed like or damaged
The condition of your TV called power supply overcurrent shutdown. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating .I would probably also check the flyback circuit and flyback transformer although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....
Hope this may help you..

The problem you have is the convergence STK chips IC i have a picture guide an a testimony how they solve the convergence problem;

Enter your model number here to find parts, if you decide to DIY also buy the service manual on same site.
You can also buy parts and service manual directly from Mitsubishi clicking here
Hope this may help;

So there is no picture or audio I assume when you turn it on?
Then it is most likely a problem with the power supply. It could be a number of things but basically somewhere in the power supply circuitry there is a problem, something most likely burnt out and if you are electronically inclined, then you should be able to find the problem rather quickly, if not, then I suggest finding someone who is to make this much easier otherwise see if anything looks or smells burnt or abnormal to start with in the power supply.
can I ask to which expert you are speaking to

Just an option that I would like to have you check. I have had experieces wherein this problem is because of some capacitors not holding a charge or leaking. Use a multitester to check the capacitors especially the ones going to the main control module on the board.
Possibly a power supply problem yes, but that would only be the case if the power supply does not give a constant supply of power. to test that you can check with a multimeter to see if the power remains constant even after it turns off. if there is still power after the turning off then that is not the problem.

Try resetting the remote. remove the batteries for about 15 minutes

Usually answered in minutes!
Thanks for your input, but I all ready tried that as far as taking out the batteries in the remote. The problem is also when you press the power button on the tv itself. Any thanks again
The mitsubishi projection tv ws-55511 is not staying on when you press the power button either on the tv or the remote. The green light comes on, but turns off with a click right away and stays off with no other lights coming on.
Thanks for help
Could it be a power supply problem, would that cause the turning off so quickly. thanks for your input about the capacitors, but it feel it it something else, but thanks for your input.
Right, the Projection tv has no picture or sound and is on for less then a sec.
This is a five yr old projection tv, never had any problems until now and only with the issue of turning on for less then a sec. and then turning off with a clicking sound, could this be (1) a fuse problem, the only fuse that I could see was ok. (2) Power supply problem (3) Bad switch, or (4) a monster in the tv., Help
what would be the best way to check out the power supply with a volt meter or any other method to see if this really is the problem. Thanks
Please say this one more time. I did not understand the answer.... Thanks
Please see comments and information in the other box's
Thanks
Please explain your answer as I did not understand or get all of your suggestion as to the problem...Thanks
I took the back off of the tv and could only find 1 fuse and it was not shorted out. where else do I look and how do I check out the power supply and any other items that you all think it might be. Where can I buy a power supply for the Mits projection tv. Please read my other comments for the rest of the story. Thanks
The Mits is either a 2003 or a 2004 model yr. out of warranty.
There seems to be others with a similar problem listed on this web site so I know that this is not the first one of its kind to happen with the unit turning on and then turning off within a half of a second with a clicking sound. the green light comes on and then goes off with the unit, no flashing, just on then off. Help
Could it be the power supply that would be doing this aswell.
