TV GOES OUT AFTER 3 SECONDS.

Press and hold the power button until it goes off. If it doesn't work, you will have to pull the plug from the console.

If you get no display when powering the unit back on, try this:

Press and hold the power button until the systems shuts off. (wait 2 seconds)

Press and hold the power button again until you here 3 beeps. Let go.

If you have a HDMI cable, plug it up, if you have AV plug it in as well. If you have both settings on your TV, be sure to have them both inserted into the system. Also, make sure that you are switching your TV from HDMI to AV and vice versa.

It should ask you to connect your controller via usb and press the PS button in

the middle of your controller. There will be a menu with 6 options. Try 1-5

This tv takes 10 seconds to turn on. Are saying that after you get a picture it then shuts off . If so replace the lamp.

Sounds like the battery may have a bad cell. The reason it quits dying is that there isn't enough juice in the battery to fire the plugs. On older pull start vehicles the stator put out the power to run the coils. On atv's with batteries, the power output is sent to the battery, and then to everything else. If the battery is bad or just dead, it eats up the current and leaves nothing to run the motor. The dash lights go out because it completely drains all current until even those lights go out. Once the motor quits runnung, there is enough current to get those lights back on again. Hope this helps...

I have the same issue. Please help us if anyone have the solution. With Great thanks.

ok this is what you do folks.... un-plug the tv from the power supply. once that is done hold the power button down on the side of the television for 30 seconds. this will release all electricity out of the tv.... then before you plug it back in hold the channel down vol up button along with the power button at the side on the tv this should reset the tv and it will start up automatically on video one. Select your source and scan for your cable channels again. If the problem is not solved then contact someone to come and clean the filter for the tv because it may be clogged along with this it can be the color wheel and may shut itself off like 3 times until it feels it is right.

sounds like an intermittent shut down which is heat related. some part , maybe one stuck on a heatsink is warming up and running too much current triggering shutdown.
to find it you can tell what is shutting down with a voltmeter, or you can heat suspected parts with a blow dryer to speed the shutdown .. or freeze spray to see if it goes beyond your shutdown time.

Your problem is TV is not getting enough power so you better buy a stabilizer and make the power to go thro the stabilizer to TV then it will get sufficient power supply everything will be smooth afterwards even the voltage problem.

whatsthe model number of your panasonic. Most panasonics mean convergence failure when the led blinks 3 times. Please respond to this post with your model number and I will post the correct ICs for your model and where you can get replacements with free instalation instructions
