SOURCE: Power light on my Toshiba 50 in plasma keeps flashing

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Display IC seems to have gone. It will be a replaceable module. Only you have to figure out which one it is. Such thing happen in electronics. Look for any burnt or bulged IC.

There is a good possibility that you had capacitors going bad in the power supply and when you unplugged it and they discharged as they should they were not capable of recharging back up to specs. I would take into a service center so no other damage occurs.

Flashing green light


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,

Solution is simple....

First, unplug power cable from the back of your TV. You will notice the flashing light is still flashing. Don't worry, go to the Second step.

Second, keep pressing on the POWER button, located on the panel at the top of your TV, to shut off your TV. This will stop the flashing light from appearing.

Third, Plug the power cable back onto your TV

Fourth, press the POWER botton ONCE, using the same button used in the Second step to turn your TV back on.

Fifth, you will see the POWER light comes on, as normal.

Sixth, using your remote control, press the green button to turn on. Your TV should work as normal.

Mitsubishi WS73713 - Now working - Timer light flashing.


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.
