Worked fine yesterday, tonight it won't come on with the button on the set or from the remote. I unplugged it, plugged it back in and the green light comes on but nothing else happens. The light will not turn off with either the switch on the set or the remote.
Before I call somebody in, I'd love to have a direction in which to steer them. I've read a lot of "this might work" suggestions, but nobody came back and said, hey, it worked. The set is about three years old and has never had a problem until this.

Re: Won't turn on.
try unplugging it and thn plug it back if the light comes for 3-5 sec. and goes off thn you will hear another click noise when it goes off. you never get a picture or sound.If im right thn there are several circuits in the tv that might cause this. the most common are the power supply and the convergence circuits. a cost of a repair for either will range around $400.00. this is a great model and well worth a repair. good luck:)

If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.
This is called the blinking green light of death-----only one of two things can cause this problem.
First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.
Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)
Try (after 70 seconds) to turn on with remote
If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.
Second: if disconnection of the front keyboard does not help, the DM unit is bad.
As you look from back of set it is large metal box at extreme left side.
The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.
Let me know if you have questions and try disconnection of the front keyboard FIRST.
id replace the tv its 15 years old and past the livlihood they usually have. it would cost more in parts to repair it than to go out and buy a new one. im sure you probably already know that though. have the tuner checked but i dont think it will save the tv but if it comes on when the cable box isnt hooked up then the problem could be in the tuner. its hard to tell. the tuner is about 100.00
