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 bold toshiba proj. t.v. red color bowed and not ali - 69189a5.pngt 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.

My toshiba TP50H15 color tv comes on then off and the light blink


The flashing power light on those Toshibas is usually caused by capacitors on the power board having failed solder connections. I have fixed them before by removing the power board and resoldering the capacitors. If you have experience with soldering and electronics it is an easy repair. Most shops will recommend replacing the entire board since their labor to repair it would probably cost more. Toshiba put out a service bulletin on this issue which a good technician should be aware of. (If memory serves the capacitors are C109 and C110.  Since your TV still turns on you probably haven't blown fuse F860 which often blows when these capacitors act up.)
If you would like further help with this please post a comment back here.

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.
