I have a JVC LT 32 EX 18 TV. When connecting my laptop over HDMI, playing on a playstation or WII the sound and picture work perfectly. When I want to watch normal TV over cable though the problems start...


If the rear inputs work consider connection for the channels with a box using one of the rear inputs--sounds like a tuner related issue and going to the rear inputs bypasses that.

Can someone please help me get my laptop working through HDMI cable onto TV on a sony VAIO VGN-FW23G. I need to know the process to do this


1. Check the computer for changing output (some computers use <F5>, <F8>, depending on which brand they are. I believe Sony uses <Function><F7> or <F7>).
2. Check what channel the HDMI port is on (e.g. AV1, HDMI1, HDMI2, etc.) - you need to know this if your TV doesn't automatically switch to the new input.
3. Plug the HDMI cable into the TV HDMI cable-in port.
4. Plug the HDMI cable into the laptop HDMI cable-out port.

5. Turn on the computer.
6. Press the <Function><F7> simultaneously ONCE. The screen should flicker and show up on TV.
7. Sometimes you may have to go to "Display Preferences" and select Dual Monitors or external monitor if your computer doesn't do it automatically. Repeat Step 6 after.

** You may have to adjust Display Resolution to 1024 x 768 or lower in order for the TV to work. After it works at a lower display (800 x 600, for example), you can adjust the resolution to the maximum the TV can accept.

JVC LCD TV (LT-42X688) input panel not working!


1. This TV has setting for the HDMI input that allows you to select the HDMI Audio or Analog(red/white wire) audio. Make sure this is correct

2. Most cable boxes are DVI not HDMI. If DVI then you actually do need to use those Red/white cables. If HDMI, refer back to #1.

3. The cable box has a setting to select the Audio output, HDMI (digital) or Analog(red/white cables). Just like #1, this has to be set.

4. Contact your cable company to help you set up the box correctly. JVC can probably help you check the TV
