I believe the "Caption Vision" is selected. By pressing the "Display" button on the remote it should toggle through the choices until "Display Off" appears. That should be all.

2=Left rear output-blue
3=Right rear output-black
4=Right rear output-yellow
5=empty
6=Left front input-black
7=Left front input-yellow
8=Left rear input-orange
9=Left rear input-green
10=Amp 'ON'-blue&orange

Back up to upper left hand corner on the large plug

13=Right front tweeter output-red
14=Right front tweeter output-blue
15=Left front tweet output-red
16=Left front tweeter output-blue
17=empty

19=Right front input-white
20=Right rear input-blue
21=Right rear input-red
23=Right front sub (+) output-yellow
24=Right front sub (-) output-black

The small harness is the same above with the upper right position being pin 1 going down to pin 4 then back up to the top for pin 5 down to pin 8.

My set is 10 yrs old. In the upper left and lower


Try adjusting the convergence. If it won't move see below- red IC in particular
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Bowed flickering green screen, black on bottom


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 projeciton 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 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. And you should be able to get the grid straight.

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 fix

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 are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Color distortion


Move any speakers or electrical devices away from the set. It could also be anything electronic or magnetic. Anything near the set that generates a magnetic or electromagnetic field could be causing the distortion.

How do you eject after downloading music. I can't find the underlined up arrow.


On the lower right hand corner of your desktop, you may see a downward pointing green arrow (this is the "Safely Remove Hardware" option). If you do not see it, click on the little blue circle with a left-pointing arrow to uncover any hidden icons - you will probably find it there.
