What adjustment you need to adjust is it to big verticaly or horizontaly or shfted right or left or convergance problem?
If you want to adjust geometry than follow this procedure---Onstd by mode press Display followed by 5 followed by
Volume + ,followed by power button .This all on remote control.
The set will go to service mode and now you can go to geometry and adjiust the size shift and etc.

    Do not try to answer this guy question, he will vote you inappropriate. All I did was to ask him a question about how bad his colors were. These set are known for having bad STKs IC which will give the customer the impression that all he need is just a adjustment.

    Good luck

The projection off my t.v. is off. Images over lap one another and I can see double of a single image. I this able to be fixed?


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

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. In some cases the TV will also not show any video. 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.

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.

Tv turns on but has a shadow around evrything


Do you have any speakers or magnets next to the tv? If so, that is not good.
It may be a convergance issue. Check to see if you have any adjustments on the back of your tv to adjust picture. If not, if may be a faulty capacitor that needs to be replaced

Tv duplicate image


your guns are off and need to be adjusted. your 3 guns (red, green and blue) are off and that would explain the funny colors and shadows. Have a tv tech come out and have a look, they can fix it for a reasonable price.

You need to take the Toshiba remote that came with the machine and go into a menu area that deals with convergence. Here's what the manual says:

This TV used 3 separate TV tubes, red, green, and blue. The R, G, and B images are pojected onto the screen wheree they converge to form a full-color picture. You can see a clear picture only when the three images converge correctly. Corvergence my drift over time, or if yo move the TV. I you can see clear images on your TV screen skip this procedure.

Make this adjustment only after the TV as been on for at least 30 minutes.

Press the TOUCH FOCUS (auto convergence) button on the front of the TV at the bottom.
The TV will enter into the convergence mode and adjust the converge automatically (that's what it says.)

TO ADJUST IT MANUALLY:

Press MENU, and the press < or > until the PICTURE menu appears.
Then press UP or DOWN to highlight CONVERGENCE.
Press < or > to display the Center Convergence menu

There's a lot more the book says, but, I can say from experience that you just go through the different sub areas of this menu and converge each color separately, and bingo, it's fixed.

Good luck.
