You are going to have to check all of the small tact switches behind the push buttons in the front of the TV set. In the past, someone may have cleaned the picture tube and the liquid dripped down onto the switches and corroded them, or one is stuck closed or the remote sensor is bad. The best way to test this would be to replace the entire switch panel in the front of the TV set. Good Luck

SOURCE: TV keeps changing channels

Out of 30 years in the repair field, I have seen this problem maybe 4 times. Once was a stuck button on the keypad of the tv. The other time was a second remote control with a book sitting on it and it would turn the tv on and off when someone would move something on the coffee table, another time was a bad solder connections on the microprocessor on the keypad circuit board and the last time was from a humorous neighbor in an apartment complex who thought he was funny who had an all in one remote control programmed for his neighbor's tv set.

I have a panasonic th42px60u my problem is that none of the controls work except the on and off volume is on but unable to increase or decrease the volume. What part do I need to buy to fix the problem,...


Good day Mr.Daniel Navarro..

The picture below is the sample 42" plasma TV (internal parts)..
11_25_2011_4_49_45_am.jpg
If your TV won't adjust volume or change channel by pressing button on the front panel..The problem could be the digital control board,it is the one that have a rectangular red on the image shown..

But before you replace the board make it sure that the control button assembly is properly connected on the said digital control board ( no loose connection or loose solder)..

Also try this remedy:
If you have remote control you can use it for the mean time to adjust the volume and channel so that you don't need to replace the digital control board..

Hope it helps..

Thanks for using fixya and purchased my service..Please don't forget to rate my answer..

"snow" screen, full volume, remotes don"t work


good day
due to the long time the buttons were not used, they tend to get stuck and this causes channels eighter to stay in one station or continou scanning. it could be resolved by spraying WD40 on the buttons and press it many times then dry it before operating the unit.

Well there is still a problem with the TV. I found that by unplugging the power cable that the digital channels worked. But, when I turned the TV on today the problem had returned, I had to take out the power cable again!

OK guys I'll save you. The tv is in hotel mode. To get it out from there you have to go in service menu but DO NOT CHANGE ANY OTHER THING IN THERE, only what i tell you. With the tv on and the K letter on the screen press in the same time vol- and ch- on the tv set. Now you'll be in service mode. On the remote press down arrow (not -channel) and you'll see up industry init. go there with ch- and press vol+ and enter. let the tv like that for few seconds and the tv will go green and hopefully industry init succsesfull will be on the screen. After that unplug the tv and replug it. Done!
