Question about Toshiba Televison & Video

1 Answer

I have a 5 yeard old Toshiba 32ZP46P which has developed a fault with the colour convergence. At times objects are outlined with bright blue or red. Other times large 'blotches' of red or blue colour distort the picture. No magnets are near. Can someone let me know if this can be repaired as this was a great television before the fault.

Hi there my tv casually has pink and green lines outlining every object on the screen. I also tried adjusting some setting with a cross section, adjusting red ad blue hues. It looked worse, not only the 3D...


There is a kit available to repair the convergence circuit...this is a convergence problem...I've seen a number of these sets where the convergence IC's go bad over time...this set is about 8 years old and about time for these components to wear out...you can go to tvrepairkits.com where you can get the parts for 65.00
here is the sku# TV-KIT-2013_50UX57B
all you will then need to do is either replace the parts yourself or have someone who knows about electronics and soldering to install the parts. Once the parts are installed you may need to go to the setup menu and reset the convergence(the crosshatch thing you adjusted)...here you are looking to get as perfect of a white line and as straight and uniform as possible

You have a convergent problem, where the red, blue, green projector lamps are out of synch. See: http://www.youtube.com/watch?v=esk4nYZKFcg for a pictorial on how to fix convergent.

Problem #1 - CONVERGENCE PROBLEM

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.

Double image in bright blue with philips model 55pw9363/17f



You may have 1 of two problems.

1) Convergence Chips are failing - Using your original remote goto the "convergence" screen. 

Try to adjust the red - UP - DOWN - LEFT - RIGHT

Next try to adjust the blue - UP - DOWN - LEFT - RIGHT

If you can move both colors in all directions you do not have a convergence issue. 

If you can't move one or more colors in one or more directions the convergence chips are defective and need to be replaced. 

If your convergence chips test out ok the most likely problem is......

2) CRT Coolant is cloudy  - The bright outline you described is one common symptom. Other symptoms include dull images, red or orange tint, halo around images.   

If you goto the site www.TvRepairKits.com - and click on "Tips" - you will find more detailed instructions on how to check the convergence.

If the shadow is only red, you can check your convergence and see if aligned first and then, check to see if in red bias my need to be turned down a bit.

Samsung HCM5525W TV red blue outlines on images


The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
