Tv power (redlight will come on powering the TV then back off

If the model here listed is correct it may be the actual power switch--it like all the front controls is a tiny micro switch--only supposed to work when pressed but can and does fail in this way--

How to prove/disprove this?

Someone needs to remove the front keyboard and unsolder that 2 pin switch---remote will with the board back still turn set on.

If it works that way either just use the remote or search for the keyboard and replace if can find one.

Only other issue possible is the microprocessor in the set could be bad and we do not want that-----both the front buttons on set and the remote go to the same place inside the set but the keyboard has priority over the remote.

If power button bad, button on the remote will not stop or correct this.

Why won't my TV turn back on even manually??

total dead usually means the fuse---unplug the set for safety and remove back cover---follow power cord just inside and you will find the fuse in a snap in holder--check to see if bad.............if good let me know and I will try to assist you.

1 have a 6 year-old Mitsubishi model WS-48511 series 1080 rear projection TV that now won't turn on. A few days ago we shut the TV off, and now when i plug it in the blinking green power light...

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.

TV does not turn on by pushing the power button on TV or using the remote.

A dead unit is commonly caused by a bad main fuse (right off the AC input). A bad fuse can be caused by something as simple as a power surge or some component on the power supply could be toast. Switch mode power supplies can be a pain to troubleshoot, specifically this one. If you find a bad fuse, replace it. If the new fuse goes out. Go find yourself a replacement board. They should be cheap enough. Goodluck.

TV won't turn on with remote or power button

if it is completely dead, then it could be a micro lock up.

take of speaker grille
open front panel with screwdriver
find DZ connector that goes to the buttons
unhook that connection and plug the tv back in
wait 2 minutes

the tv may now work with the remote, the buttons are bad, common mits issue.

if this doesnt solve, or you have flashing leds, let me know.

ok is the set completlely dead. DOEs the Led on the front flash. if it does not flash this is an indication of a primary power interuption. POSSIbley main fuse. Now generally the main fuse does not blow unless there something else wrong. some other component shorted. Now if the light flashes then this is an indication that the main fuse is still good and that the processor is getting power and that it has detected a condition that requires it to shut down. ussaly a high voltage issue

Panasonic TC-25V50A TV circuit schematic needed to try and fault find. Set completely dead except for red led signifying power on. Power fuse OK. No blown out capacitors or resistors apparent. Can you...

Success! After finding nothing with a visual check I dropped the set about 3inches and all is well. Must be a mechanical connection problem. Probably a dry joint, will resolder if it happens again. John

RCA Projection TV MM52110 Won't Power Up

Being able to read a schematic and understanding how a TV works are two different things. These chassis that RCA used in these sets can be somewhat complex to troubleshoot. I would geuess that unless the power light comes on at all then you have a dead power supply in the TV.
