Weird problem not 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

• Screen Looks 3-D
• Colors wont align

Check for convergence failure. Convergence Gallery Try adjusting convergence in user menu. If convergence display is messed up or adjustments do not work correctly, you have an Intermittent short circuit within an STK IC.

Look at menu screen with an unused input (antenna or video). If menu is stable and clear, TV may be OK and you may have a signal input problem.

If it is not poor quality input signal or convergence problem, someone has to troubleshoot to determine if it is a Video, Processing, Power supply or CRT related problem.

Most likely convergence.

Hi,
Have you tried pressing the 'input' button again this time to switch from video to tv? This happens in quite a few cases where 1 remote is used for many products. Please try and let me know.

Do you have the remote? You will need to cycle through the inputs to get to video 1 or 3. You might have the buttons on the front of your tv that says tv/video or tv/vcr. If not go down the channels past 1 and it might automatically switch through the video input selections. For any of these solutions have the PS2 plugged into video 1 and turned on. Hope this helps.

I hooked up a Pioneer DVD player to my TV and when I play a DVD the volume cannot be controlled by the TV. It just plays at one level and on the louder side. When I'm watching regular TV and the DVD player is on and playing a disc I start to hear the DVD soundtrack at the same time as the whatever I'm watching on TV. I should not be able to hear anything until I switch over to Video 1. Any suggestions?

at JVC Support Page , download owners manual , listed above , on page 35 , it appears you should press INPUT button and cycle thru TV / video 1 / video 2 / V2 component / and video .

depending what video input option you used to hook up your Xbox to , you should be able to figure it out from here.

JVC may allow warranty exception or some accomodation for 15 days out. You have 2 seperate issues

1. White lines spreading is probably a video process problem. I think this TV has 3 Boards inside. Middle one is most likely suspect followed by the one on the Right

2. HDMI input not working is because they were turned OFF. JVC TV's have a sensor that will shut off the HDMI if the TV's back cover is removed. This must be reset in the Service Menu.

The most likely cause is shorted convergence chips and possibly a few pico fuses.

it looks like theres a wave in the top of my screen on my jvc av-48wp30 not sure but i think it has something to do with the bulbs because the projection mirror wasfine and all wires seemed to be hooked up properly.. can you help? tell me where i can find the bulbs to replace them?

It sounds very much like your receiver needs repair by Sony.
