Question about Panasonic TH-42PX500U 42 in. Plasma Television
I own panasonic th-42px500 flat screen tv. This week for no reason it displays " no channel available" when I try to access cable channels yet it still works if I play a dvd movie. How can I fix this problem?we've had this tv for just over one year. it was manufactured in Nov.2005
Unplug it for 10 secs and plug it back in then wait 10 more seconds and turn it on with the on/off switch. Unplugging makes it reload the firmware, but on/off does not. If that doesn't work try a factory reset. For my Panasonic you do this. Open front door to get at the buttons. Turn TV off. Press and hold the OK button and at the same time press and HOLD the on/off switch for about 3 secs. You should get a self check screen that will last a little while and then the TV will go to the menu screen.
