Jvc av27d201 tv screen problem

Hello i have a tv screen issue with my jvc tv. the issue is that the screen distortes and i get multiple lines throughout the screen and periodically will go to a bright vertical flatline in the middle of the screen. often all i need to do is tap around the screen on the outside of the tv and the picture comes back. over time im having to smack the tv more often and sometimes harder to get screen to come back. most of the time when i get the screen back it will give me a perfect screen until i turn it off. althouth this problem is getting worse. is this a possible part replacement issue and if so what part. it seems the tube is fine because i can still get a perfect picture at times. is my tv a throw away or do you think it can be fixed?? thanks shawn

JVC AV-48WP30 problem starting up


The old video card has seen better days, methinks. All those symptoms lead one to conclude it needs a 'substitute' to enter the field, or call a long TV time out(too much pro and super bowl isms, eh?)..

Are you planning on doing this yourself?

I have a samsung model: LN-T4061FX. when turning on the tv, it has a distorted picture, the sound is good. if i smack that **** out of the top of the tv after multiple tries the screen will eventually


flext tab bond is the most likliest cause. They tend to lose their bonds and then usually hitting the top edge of the screen will lock it in. Flex tab issues will make part of the screen take on distortions and slow response of the pictures movements in the screen

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

93a1209.pngCONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com
