You can adjust the lines and make them straight. You can also in the same process, make them line up.
1. With the TV on, press the mute button the remote control so that you have picture but no sound.
2. With remote in one hand (holding it as far from the TV as you can but still be able to reach the TV with your other hand), press and hold the mute button again, with the other hand, using the control panel underneath the screen, press the menu button on the TV set.
You will notice an "S" on the screen on the right hand side about 2/3 from the left, halfway up the screen (If you did this right).
This means you are in service mode.
With the remote, curse right only once and you will have some information displayed in the upper left. The top line is Item, the one underneath is Data.
Press "7." This will display the built in cross hatch pattern. You can move the line around with the directional circle located at the center of the remote. Using the "3" button, you can decide which color to move. To move the curser to a new location, The number pad doubles as a direction key pad. (2-up), (4-left), (6-right), (8-down). To simplify the process, you can eliminate the red or blue or green lines and only focus on one color at a time. "0" will shut on/off the green line. "100 button" will shut on/off the red line. "CH RTN or Enter will shut on/off the blue line.
"7" will exit the process as well as get you there.
Power off when you are done and turn back on.
Repeat as needed.

Please rate this solution after reading.

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.

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.

Toshiba 50H72 have blue and yellow ghosts


Sounds like your convergence circuit went out. It lines up the red,green and blue picture tubes so the colors are lined up. Usually these TVs all use the same type of IC chips called "STKs" both usually get replaced along with any resistors etc.. around these chips that may have burned up. Depending on who fixes it could be around $300-400 parts and labor.

Toshiba TP50G50 Theaterview picture is double with red color only


Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!
