Hello:

Thanks for this forum.

I have a Toshiba 48" rear projection TV which started to show red and green lines on the left side of the screen and have also started affecting the left-hand focus of the image shown on the screen. I have had this TV for 14 years and had a projection adjustment done once before.

Thank you in advance for your assistance.

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 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

Covergence problems or alingment , its has three colors without alingment please help me!!!


manual convergence should fix the problem if it does not the set most likely either has a bulb burnt out or a bulbs power / focus needs to be adjusted by taking off the panel and finding a 6 screw control panel

...
...

should look like that 3 screws in a row on top of another three screws each of thees control the power and focus of each color this is a somewhat delicate process and is a huge pain on larger tvs that you cannot completely see the picture or color while you are directly under in front of it so I had my gf come in the room and sit across to let me know which color was doing what if you dont have someone you will need to check after each adjustment

now the diagnostic
as i said each screw controls a colors power and focus the focus is used if you see an outline of a color around pictures if everyone looks like a dead jedi with a blue aura around them the blue focus needs to be adjusted and so on for each color if you skies or blue screens seem feint your blue power probably needs to be turned up and so on for each color

if through the course of this you can see the bulbs and notice one is out your probably looking at dealing with the color issue until the time you can purchase a new tv as the cost of the bulb and the technician needed to install it as they are wired to a circuit board and requires technical knowledge and tools


hope this helped

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Toshiba theaterview 50in rear projection tv


Look at it on the QVC channel where you have boxes with straight lines. If any of the 3 colors are bowed and 1 inch off, then it needs parts inside. If the colors are straight and only 1/4 inch off, you can adjust it. Using the remote, in the menus find convergence to adjust. Your user manual will explain it. At WWW.Toshiba.com you can download the manual if you do not have it.

Convergence problem- right side red out?


As long a the picture is not bowed you may have a convergence module bad or have to enter convergence service menu to adjust If bowed at all the convergence ic's are bad or just a resistor in the convergence circuit is out of its value. These are possibilities but it still could be the ic's
