Hi, my tv just turned off on me. When I turn it on the TV screen flashes and turns off again. I have a solid green light on the power button but no sound or picture. Any ideas

check inside for loose connections

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

Have you even replaced the bulb / lamp on this TV - other than the green light - did they turn solid red / orange at any point? My initial thought is you need to replace the bulb.

Tv probally needed a new tv projection lamp.This tv has not been change it projection lamp like 1 1/2 or 2 years already?Tv been on and used it like 4 or 5 hours everyday?Yes,than the tv flashing or solid on green LED light is on have a word "LAMP" written on it tv bazel frame?Yes,tv 100% require a new tv projection lamp replacement.

I found this on another website, most likely it is your power supply capacitors.

1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.


2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.


3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.


4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.


5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.


6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

1. DM Module Capacitors have FAILED.
2. DM Module is defective.
3. EEPROM Board failure
4. Power Supply failure.

Sharp tv are famous for this problems.Take ur tv aparts,where the a/c power cord go into it.That ur tv power supply board,check for all those dead leakage capacitors parts that bulges up on it top or puff up on it top.Than it ur power supply board,replaced those dead leakages capicitors or replaced the whole power supply board.No leakage capcitors on the power supply board.Than it 100% the Tuner board it dead,this board is where the coalax broacast tv signal cable go into it.This board can't not be repair only replaced,because it alway some ICS it the problems it dead on this Tuner board.Tries websties like Shopjimmy.com,Ebay.com to buy either or both refurbishes the power supply board or the Tuner board.

this is a inverter board defective. please change-it

Did you try this yet

SYSTEM RESET
If the TV will not respond to either the remote control
or the front panel controls and/or will not power Off,
press the SYSTEM RESET button with a pointed item
like the end point of a paperclip. The TV will turn Off
and the TIMER light will flash quickly for about one
minute. When the TIMER light stops flashing, you may
turn on the TV again. Changes you made the last time
the TV was On before you used the SYSTEM RESET
button may be lost, however, the changes you made
previously are not lost.
POWER/TIMER Indicator
The green light is a multi-function indicator. This light
will flash rapidly for about one minute each time the TV
is plugged into the wall electrical outlet, when power
is restored after a power failure, or using the SYSTEM
RESET button. Do not attempt to turn on the TV again
during this period. Wait for the flashing to stop and
the light to turn off, before attempting to turn the TV
on. While the TV is powered on, the light illuminates
steadily. If the TV has been programmed to turn on
automatically using the Timer feature,

hi there,

Check for bad solder on convergence module. May have bad stk's. Do not neglect looking for bad solder on dsignal and defl boards. Mitsubishi is very prone to bad solder.

My Mitsubishi WS-73713 had the same blinking green timer light problem and would not turn on. I tried the reset button and unplugging power to no avail. I found that by simultaneously holding down the remote control "power" button and "volume" button for about 30 seconds the blinking light would go out and a solid green light would come on. Even though the solid green light came on the unit would still not power up. After doing this several times however the unit did finally power up in a normal mode and appears to be working again. It's worth trying before calling in for an expensive repair. PS - From here on out I'm sticking with SONY or Toshiba sets which have given be great service.
