TV MITSUBISHI 1080 WILL NOT STAY ON

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.


REGARDS, SD TECH

you have a bad or leaky capacitor in the power supply section...if you can dismantle the back casing look for the power supply and check if there's a bulgy capacitor mostly electrolytic type....replace w/ same value..it's best if you brought it in a tv service center

cracked power supply board.

Probably 1500.00 new, but that's an old set. If your trying to sell it I would ask 350.00 for it, if it works.

Unplug for a few should correct!

STKs,one of them controls startup if bad TV will not come on.STKs are big black ICs will have part# on them. call Mats for parts you have 2 replace both. 1-800-628-1118

Ur power ic inverter board is dead.
U need a new one.

Most likely burned out lamp.

You don't.
It should automatically switch to 1080 when and only when there is a HD signal present. Otherwise it will be in 480 and you will need to use the format button on the remote to change the picture size. If it does not switch to 1080 and you know for sure you have a true HD signal present, there is a problem with the unit.
Hope this helps,
