Question about JVC AV-48P775 48" HDTV
My T.V. wont put out sound, but the display shows it moving up and down. And in the sound menu The Bass, treble, and balance show zeros. and these options are inaccessable. Do I need a repair man?
In the menu for initial setup look for a setting for center channel and turn it off. If it is on you will have no sound because it turns the TV speaker into the center speaker for a surrond sound receiver input.

Tips for a great answer:
Channel guard and V-Chip settings are protected by a four-digit lock code. Your TV comes
pre-set with a lock code of "0000". You may change the code to any four-digit number you
wish. To change the lock code, follow the steps below.
Press the MENU button
Press [UP/Down] button to SET LOCK CODE.
Press [=> / <=] buttons to operate [lock icon appears]
Press ZERO to acess the lock code. The first digit will be highligted.
Press [ => / <=] button to select the number.
Press [Up/Down] button to move the next digit and continue to follow these directions for all the four digits.
Press OK button to finish.
Press the menu button when finished
DO THIS AFTER UNPLUG THE TV FROM AC MAINS WALL SOCKET, AND LEAVE IT FOR ABOUT 30 MINUTES OR SO, REPLUG IT TO ac MAINS, AND DO ALL THE ABOVE SAID PROCEEDINGS. THIS PROCESS WILL ERASE ALL THE V-VHIP CODES, IF SET, AND WILL ALLOW YOU TO SET AN OTHER OF YOUR OWN. The default V-Chip code is . Ok.
