The position(s) of one or more of the CRTs has shifted during the move. You may need mechanical alignment to bring it close enough for the convergence to be within range.

My Toshiba 53H71 rear projection TV's picture looks like double vision with a heavy tint outline how can I fix this???


Hi,
Double vision/ picture problem occurs due to failure of convergence output ICs in rear projection tv and it is common problem of projection tvs.
Please replace convergence output ICs in tv to solve the issue, there is convergence repair kit available for $70 on This Site that has required parts/ ICs, instructions about how to replace ICs etc for a handy person.

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 button. If it 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.

Good Day,
The TV has a convergence problem; the IC’s for that circuit will need to be replaced. The cost for this repair runs around $450.00 or more.

Replace the defective Convergence Output IC Part Number
23905094 (STK392-110) using the revised “T” version IC Part Number
23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version. Inspect the Convergence Output IC’s for the “T” type version as
shown in Figure 2. Replace the Convergence Output IC’s using the “T”
type version Part Number 23135090 (STK392-110T).

Thanks for choosing FixYA, Big Irish

Sony rear projestion TV has blurry picture.


sounds as if your convergence needs to be set. either through the menu on the tv or remote you need to get to the convergence set screen and you need to line up the crosshairs. this usually happens when the tv is moved or bumped.
