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..

My Insignia LCD 42" only


It sounds like it has main board problem, leave it unplug for about an hour to let it reset itself to see if it will work again. It can also be unstable power supply problem.

Samsung 40 hd tv the vol will not come down from 100 percent . I try to turn the vol down and it will not turn down. what can I do. tks mike


I presume that the volume will not turn down from either the remote control or the volume buttons on the side of the tv. If the volume down button works on the side of the tv then the remote control is suspect to be faulty. If neither remote or tv volume buttons work then check whether the channel buttons work on the tv (not remote). If none of these work then check the input connection from the buttons /infra red reciver to the main pcb. This is a push on cable connector. As a point, also check that the volume up button on the tv is not stuck in, and feels the same as the other buttons when pressed.

Sony BRAVIA volume problem


I had this same issue, and solved it by putting the TV in "Theater Mode', which can be acheived by hitting the "Theater" button on the remote.

Front panel buttons on Philips rear projection do random things


Leaky tact switches on control panel. Part number is 242212802742. Takes 6. They will cost you around 6.00 a piece. Lower front panel pulls off. Be careful as there are two cables attached to htis panel. This should take care of your issues.

No picture, stuck on Video 1, volume self-adjust to maximum


the tacticle (micro switches)on the front of the main chassis have most likely gotten wet at some time,I suggest replacing them all.
