** TV won't turn on.** No picture or sound. Please Help !

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.

Sony blinking codes

If i remember correctly ten blinks means a high voltage error.
The only thing you could try is unplugging the power cord then plug it back in and try turning on the tv. If it still won't turn on try unplugging the power cord for five hours or longer and try again. If it still won't turn on it would be best to find a local repair shop that works on sony tv's and have them repair it for 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.

Rear protector tv stuck on standby and won't turn

Possible there is fault in the processor section of the main board. You will need to check the main rail of 5 volt to the processor and allied section to start with the probe. If absent the 5 volt regulator must be checked. If present the processor and in many cases the board is a suspect as component level work might be difficult unless equipped.

The red "on" light is blinking and the TV

a suggestion: unplug set and try to turn on again; if power light blinks does it blink in a sequence?

3 blinks repeated will mean a problem in the Convergence area.

5 blinks repeated will mean a short on the 140 volt line.

These are the two most common error codes.

Green light turns on for 1 or 2 seconds and then goes off. tv won't turn on, no picture.

Have you tried accessing the self diagnosis feature by pressing the menu and device buttons both together and holding for for 5 seconds? If not try that and let me know the error code. It will be a two digit blink sequence which will repeat a few times. Let me know what the blink sequence is.

Tv won turn on

This could be caused by a bad HV block. I would not take on replacing unless you know your way around HV circuits on Projection TV's. I would call a repair facility to give you a estimate to repair.
