Panasonic Viera 42" TV won't tun on

There is a red light next to the manual power button that flashes 12 times.  I cannot turn the TV on manually or with a remote.  I've pulled the power cord out for a few minutes, plugged it back in and encoutered the same problems.
Any suggestions?

    when i was viewing the tv it was fine and then all of a sudden, no picture.
    I have tried to hold down the power button on the remote but to no avail. Did you find any solution to this problem, big worry!

    My Panasonic Viera does the exact same thing. I always have to unplug it and plug it back in for it to work. This is so frustrating.

This problem happens when you connect a DVI-HDMI input to the back of the set. It can happen other ways too though. Press and hold your power button, which will reset the unit to it's factory defaults, and should return it to normal use.

I have a sharp aquos tv model lc-32m400x. When i turn the power on via button at the back the green light comes on for about 10secs then turns to red and flashes about every 11/2 - 2secs. Any ideas.


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sound is pinned at 100% output. Remote nor physical buttons on device are working.


If any of the buttons on the remote or tv work, then try going into the menu and turning the sound down manually.

My sony wega kf-50E200A tv keeps turning off. during each cycle the green light blinks 42 times and the tv comes on again for about 3 minutes and it happens all over again


More than likely the power supply is defective, but without testing and the repair manual that is just a guess, you make the decision to replace or repair the TV.
