You need to replace or have the convergennce IC's replaced. This is not a very hard job to do, but will take some soldering skills. Good Luck

I have a 65 inch toshiba cinema series it's says

if a large rear projection set that just says HD, it likely is HD ready which means it needs a set top box connected to the Colorstream input marked 1080 on the rear of the set--It will only likely be 1080i and not p---owner manual would confirm this.

Re: Toshiba 65 in Cinema Series - 12 years old. Color Separation. Green bow at top center of screen, red and blue double images tilting upwards toward sides. Sometimes clears unassisted after set has...

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.

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 57hx81 tv has a bow at bottom of screen and blue in color tried using toush focus & got error then tried to focus manually & couldn't get the bottom lines to focus all the way down

noted in the owners manual, if auto focus returns message "error" , it suggests to use manual convergence setting..failing that, is it resonable to suspect that the STK-392-110 (convergence (2)chips)are beginning to fail, bendt horizonital lines is the effect. you can check all the resistors and pico fuses (power board)near the chips for shorts, chances are they are ok. seeing that there is somewhat of a picture (kinda like 3-d). i would repaired it!.. while your there do the hyperboard repair as well by replacing the 10 caps with 16v@10uf. (causing a wavy vertical distortion effect).

Mitsubishi Convergence issue

If the screen is out of focus you probably need to adjust the focus on the focus block it is usually located behind the front grill, there are 6 adjustment screws on this block, leave the screen controls along just adjust the red, green, and blue focus screws. When converging a set everything is converged to the green, the blue and red are suppose to come to the green.

Double Vision & Bowed Screen

Chances are that the convergence amps are bad.
If those are mounted on a separate board, replacing the board would be the easiest thing to do. Running the magic focus or touching up the convergence in the customer menu may be required.

Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.
