This TV has funny inputs. Video 4 and 5 have three inputs for the single buttons. I suggest using the input button on the side of the TV. Press the button, wait 3 second, then press again to go to the next input. This way you will cycle through all of your inputs.

If you are using HDMI it is likely that the cable box output is not setup.

JVC LT-50A330 TV. Sound but no picture. Screen is blue


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

No picture just sound thru dish network


There are a few reasons that this could happen. The main reason would be that the tv is on the incorrect channel or input. You will want to make sure that if you are at TV1, the channel is on 3 or 4, and an input if needed, such as VIDEO 1 or 2. If at TV2, the channel needs to be on 60 or 73. Cabling is another reason this could be. You want to make sure that if you are at TV1, all cables going from the receiver to the TV are connected on the back of the receiver at the green TV1 location. For TV2, the cable needs to be connected to the HOME DISTRIBUTION output on the back of the receiver.

No Picture


Backlight Bulb is out.
You cannot purchase these as a spare part, you must purchase the complete backlight.
Backlight cost is more than or equal to a new TV
You may sell this TV on Ebay (list your exact symptom). Start at 100 you will get about 250. Take this money and buy a new TV.
LCD backlights don't fail often but when they do there are no part available to repair them so you get stuck buying the complete assembly part. This is more expensive than a new TV since LCD prices have dropped so much in recent years.

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
