Clean the head

It is possible that the heads in your JVC video camera need cleaning, especially if the playback picture looks distorted and similar to a VHS tape played on a player with dirty heads. Dirty or worn-out heads can cause playback issues, including poor picture quality, distorted images, and tracking problems.
To clean the heads in your JVC video camera, you can try the following steps:

1. Purchase a head cleaning cassette: You can find head cleaning cassettes online or in electronics stores. Make sure to get one that is compatible with your JVC video camera.
2. Insert the cleaning cassette: Open the tape compartment on your JVC video camera and insert the head cleaning cassette. Close the tape compartment.
3. Run the cleaning tape: Press the play button on your JVC video camera to run the cleaning tape. The cleaning tape will clean the video heads as it plays.
4. Eject the cleaning tape: Once the cleaning tape has finished playing, eject it from your JVC video camera.
5. Test your tapes: Try playing your tapes again to see if the picture quality has improved.

If cleaning the heads does not solve the problem, it is possible that there is a more serious issue with your JVC video camera.

Defective LCD panel, it is not worth to replace it.

Hi There are three things that can cause this problem. Your lcd screen, t-con board or the signal board. Most likelly in your case since you say it's only half the screen it's going to be your t-con board. You can try removing it and cleaning all the contacts and replacing it see if that helps. If that doesn't help then replace it. If that does not solve it then it's going to be your screen.

You can get parts at www.interliquidparts.com

you have to make sure that the picture you want to use as a background has similar resolution to that you are using in your actual display. for example if you are using 800x600 resolution you should have a picture close to that so it doesnt look distorted.

the video playback is sampled off the video out and independently processed sorta like a TV signal to project on the lcd screen.
horizontal lines means you lost sync circuit and needs troubleshooting. Hopefully maybe a bad connection with a ribbon cable for the ICs and components are hard to change and jammed tight. I would order a video board.

Gimbo again. Think LCD damaged will need to repair. Pics. as normal when viewed or printed.
Why has nobody commented?
How much to replace screen? Any ideas?

This is caused by a failure of the main board. The failure causes the refresh rate of the unit to be off creating a trailing or ghost effect. This will require a technician to replace that board though. Hope this help.

hi, I wish you wouldve given us more details regarding the kind of distortion you get on the LCD screen. if objects kinda fuzz out, it can be related to worn headdrum, i.e. worn heads. The heads are tuned with the input-capacitance of the PB-amplifier on the white-frequency of the recorded RF(is in FM with high frequencies on white) . The wear of the heads will decrease their inductance so the tuned frequency is going up.The video-amplifier and demodulator circuits can`t compensate it. Another reason can be a misaligned FM modulator( frequencies for black and white are not set correctly). Finally the AVC of the camera itself can be faulty. The guiding posts will never cause such problem but their setscrews tends to get loose. Tighten them carefully. Good luck
