Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

SOURCE: Warped Picture, Separated colors

Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.

SOURCE: 50hx70 blue projection light is concaced at top and bottom of tv

When the convergence amplifier ICs go bad (STK392-xxx), they RARELY cause more than one color to go out. The fact that the top and bottom of the picture are effected indicates the vertical convergence IC. Replace both, and while you're in there check the bias resistors... it is likely one of these is open. Once the ICs have been replaced (as well as any open resistors), customer convergence followed up with the auto convergence should do the trick.

There are two problems here but may be caused by one component

The flyback transformer or transistor equivalent is faulty The colors are warped convergence controls which may be due to a faulty sustain board or part of the first problem. DIY is not an option and repair estimate is about $3-400.00

I have a tz61v61 toshiba rear projection. The bottom half of the screeen is ghosting red, blue and green. it looks like 3d without the glasses. top half of screen is fine.


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Picture looks like it is warped at the bottom and top of the picture. Have picture, no problem there, just not a centered picture anymore. Looks like the top of a half moon on the top and botom.


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 images of convergence problems.

Try unplugging TV while it is on and let sit for 20 minutes. Re-connect and see...
It sounds like your horzontal control is bad. It requires a new circuit board.

Toshiba tos-50h81 convergence issue


you have this in your menu. but your menu will not adjust and fix your problem. if all three colors are bowed in at top and bottom...red green and blue... then you need to change all convergance ic's and check fuses. also there might be some solder in fuses hiding on the board. Need to also check all fuses around conv ic's and around conv yoke plugs.
good luck.
