No Picture or sound on my JVC HD-56FN97 Television


No, if bulb is bad you will not see anything on screen.

Are outside sources connected to different inputs on TV?

My screen went blue but sound still works


The screen goes blue when the video signal is missing - check the cables. If the cables are ok then check all the other video inputs - if all are dead then the AV board is faulty, fix it or replace it.

Jvc av-48wp74 48 in widescreen green projector problem


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Hi, convergence amps have failed, your going to need a tech for that repair, involves un--soldering and re-installing parts as well as an alignment, hope this helps, video-tek
