When turning on PIP (Picture-In-Picture) I keep getting the same channel that's on the main screen. 

PIP requires 2 television tuners. The TV supplies one, the second is usually supplied by a VCR. The VCR's audio and video outputs must be connected to the television's audio and video input. If you are using a cable box, a 2 way splitter must be used and the connections are as follows. Main cable goes into the splitter. One line from splitter goes to cable box's in-jack. The output jack of the cable box goes to the VCR's antenna input. The VCR connects to the TV as described above. The TV tuner will control the main picture, the cable box will control the small picture.

What's the difference in COMPU LINK and A/V COMPU LINK? 

COMPU LINK refers specifically to audio components, for example, cassette decks or CD players. A/V COMPU LINK refers to VCR, TV and some receivers. A receiver may be COMPU LINK but not A/V COMPU LINK. The feature difference? Each flavor of COMPU LINK allows components to "talk" to each other with easy operation from the remote control. However, with A/V COMPU LINK the user can also control video components as well. In addition, a user can "turn-on" their entire Home Theater System by simply pushing a prerecorded videotape into their VCR.

When I use A/V COMPU LINK, why does my TV always pick video input 2? 

The TV has an S-Video input on input 1. The receiver you are using has no S-Video Jacks. The receiver communicates this to the TV, which picks input 2. It does this because a S-VHS VCR or laser disc player may be connected to input one. Therefore, simply connect your video source to input 2.

I get a big black square box covering 90% of my picture. 

This is not channel guard or a malfunction. This is a function of the closed caption circuit available for future use called text mode. Simply press close the caption button on the TV remote until the square disappears.

I have a JVC television with two tuner Picture in a Picture, and a cable box, but get the same picture on both screens. Why? 

The problem stems from the use of the cable box. The cable box outputs only one channel to the TV's two tuners. Since both tuners are receiving the same information, both pictures will be the same. Elimination of the cable box should solve the problem. If eliminating the cable box is not feasible, use the hookup outlined in question number 7.

Why can't I set the clock on my AV27790, AV32790, or AV35790 model television? 

The above model televisions have a Feature called TV Guide+. This feature which downloads TV program information also downloads the current time. Once the TV Guide+ feature is set up it is impossible to adjust the clock manually.

My PIP works on my twin tuner JVC television but I get channels 2-13 on the small screen and all my cable channels on the large screen. How do I get all my channels on both screens? 

Turn the PIP function ON. Then press the SWAP button to switch the pictures. Now press the MENU Up or Down Keys until you reach the TUNER MODE setting. At this point press the MENU Left or Right keys to set it to CABLE. You will now get all your cable channels in both the large and small pictures.

When watching my JVC Stereo Television on some channels I get the wrong audio for the station or no sound at all. How can I solve this? 

Your Television is designed to receive Stereo broadcasts. It is also capable of receiving SAP or Second Audio Programs available from TV stations. Some stations broadcast radio stations, weather, foreign language or nothing at all on this frequency. If your TV was mistakenly set to receive SAP, then you may be getting the wrong audio or no audio on some stations. To alleviate this problem access the MTS STATUS screen of your TV MENU and make sure you highlight STEREO instead of SAP. This should solve the problem.

Will a TV or VCR designed for use in the U.S. work overseas? 

TVs and VCRs designed for use in the U.S. use a broadcast system called NTSC. The NTSC system is primarily used in North America and Japan. Most other countries use either a system called PAL or SECAM. These three systems are incompatible with one another. An NTSC TV or VCR will not receive or playback information from a PAL or SECAM broadcast or tape. The same is true of the other systems. There are some TVs and VCRs which are capable of handling all three systems and both would be needed to play tapes of different systems. Unfortunately U.S. JVC corporation does not market such products in the United States.

Our new generation of chassis design means brilliant whites, and velvity black, for a dynamic high contrast picture.

Apacon is a circuit that enhances picture sharpness. Details are enhanced to deliver a crisper, sharper picture.

SAP (Second Audio Program) decodes any second language translation that may be part of the program.

All 20 inch and larger TV's are designed with front-firing speakers. Because the speakers are aimed directly at the viewer, a rich, clear sound stream
is created that enhances both music soundtracks and dialog.

You can switch the TV's speakers to off when you want to listen to a multi-channel AV receiver as the sound system.

Use the fixed Audio Output if you connect the TV sound to a remote controlled AV receiver.
