Tv will not turn on manually or with remote

I would try the reset button in the front. Unplug the set push the reset and plug it back in.

ok, a model number would be helpful but:

when set turns off and green power light goes out: on the front of the set press and hold both the menu and input (device) buttons at the same time for at least five seconds and let both go.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it for a total of 5 times.

This is the error code and indicates where the problem may be---let me know what code you find and I will tell you what it means.

it may or may not have the self check but try this:

When green light comes on and goes off ON THE FRONT OF THE SET press and hold the menu and input buttons at same time for 5 seconds or more and release both.

Power light should blink a two digit error code like 2 blinks, 2 blinks and pause--repeat it several times--all their sets after 1999 have this feature.

If yours does not someone has to go inside and measure voltages etc to find problem---a lot of the older ones develop broken solder connections and the chassis would have to be examined for that.

That model does not have a red light---Green.

If set powers up for a few seconds (green power light) and goes out do the self check the model indicated has:

On front of set (not with remote) press and hold both the input and menu buttons for at least 5 seconds and release both.

Green power light will blink a two digit error code like 2 blinks, 2 blinks a pause and repeat it several times.

Let me know what error code you find (if you have unplugged the set that will clear all errors and you have to plug it in and try to turn set on again---when it fails do the self check)

not knowing model number I will suggest a few things: if green power light comes on for a few seconds and goes out:

On front of set press and hold both the Menu and Input (device) buttons at same time for at least 5 seconds and release both.

Power light should blink a two digit error code like 2 blinks,,2 blinks,, a pause and repeat it several times.

This is a error code that indicates what area problem is in, let me know what error code you find and I will tell you what it means----if set has been unplugged you will have to try to turn it on and let it fail before you go for the error code.

i have a mitsubishi hd 1080 tv when i turn it on it turn of with 2 sec.what is the problem

i have the same exact problem. My mitsubishi HD 1080 series suddenly stopped working. when i hit the on button, the on-light goes on for a second and then goes right off. any luck figuring this out?

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

Are you sure its the right remote? Verify TV mode on remote if equiped with mode switch. Drain the remote by removing batteries.

sounds like it has a bad DM assy, or a bad 9v reg ic.
the dm can be repaired, there are 4 capacitors on it that need to be replaced.
