1) turned off the tv
2) pressed the power button on the tv
3) unplugged from the back of the TV set it while holding the POWER button
4) pluggin in the power cord while still holding the power button.
NO USE. did the exact same thing again while releasing the power button while plugging in the power cable. what am i doing wrong?
I don't think you're doing it exactly as the manual says to do it.
All you have to do is turn the TV on, then either press and hold the front Power button on the front of the TV for several seconds until it reboots, OR turn the TV on and simply unplug it for several seconds then plug it back in again. Both of these methods have worked to bring up the initial Viewing Environment menu on various Panasonics.
i pressed it and held it in place for more then 30 sec
while holding it i unplugged the tv and then let go of the power
i HEARD a click sound...
n then pluged it in after few second and voila
You still did it incorrectly then. You don't have to unplug it if you hold the power button in long enough; it will reboot all by itself. By unplugging it while holding the button in you just short-cutted the process so there was no need to hold the button in anyway.
