the green light blinking is normal if set has been unplugged--when set is plugged back it should blink for about 70 seconds and then go out--then you can try to turn it on---it is the DM unit inside the set booting up.
If the light just blinks and never stops you have likely bad caps in the DM unit---there are kits available for that.
The other possible reason is that so called reset switch may be bad--fairly easy way to find that out and it is more common than you would think, let me know if you have questions.
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.
Probably a blown pico fuse on the circuit board, convergence amplifier issue, or blown HOT transistor. Could also be a solder connection on the pc board other bad component. Count the blinks and note any pauses in blinking. This could be a trouble code. Type into google your tv and model number and the words "troublecode ## " if you had one or "steady blinking green light" if it just continuously blinks wit no pauses. See where that takes you... Hope that helps some.
The TV indicates an error code 22 (short circuit protection). Check 2 STK392-570 convergence IC for shorts and 5amps pico fuse for open. I usually replace both STK's.
Sounds like your TV is overheating. How dirty is the filter on the side? Is the fan on the back turning ok:? Does it look real dirty? Is so, a good cleaning is in order. Also, there is a fan under the lamp. Can you determine if it is working...the air flow may be obstructed (from the clogged filter) and it takes some additional time to cool.
my tv has menu and enter buttons if thats the same then that did'nt work
any ideas
my model number is ws65813
