I have a JVC TH-S3 surround sound system and would like to know if I can l watch television in surround sound as i can watch dvd's and listen to the radio in surround sound. thanks


Yes you can get simulated 5.1 surround sound from your TV as well as radio. Just switch the JVC surround mode to Pro Logic II movies or music In some systems it will display only PLII.
Just connect the TV audio out to the JVC Aux input at the back ( red and white sockets ).

I opened the set and the blue projecter does not show image like the red and the green. does the blue projecter need to be replaced?


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Pioneer PRO 510HD - 53"


Boards can run 250 - 400.00 on average. You may be better off just repairing the board parts for around 65.00

See below

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

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.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Getting red, blue and green halos around images


I had a similar problem with red halos around images on my Hitachi rear projection TV. The problem was that the red convergence chip burned out. I replaced that and that fixed the problem. I found several forum posts on similar symptoms and fixes for Sony rear projection TVs by searching for "Sony rear projection convergence problem." Likely you've already tried the auto-convergence function for your set, if it has that.
