    Your TV most likely has one of two possible problems.

    Problem #1: Convergence Chip Failure ( common problem )

    Here are some of the most common symptoms and example photos of a convergence problem


    • 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.



    Here is a quick test....

    Using your original remote go-to the tv settings then goto the convergence section.

    Try to adjust the red and then the blue convergence.



    You should be able to move them up, down, left, and right.

    If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

    Solution #1

    You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


    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.

    Picture of a set that needs the fluid changed.

    Solution #2


    What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Your TV has a failure of its convergence output ICs and perhaps some of the convergence circuit's other associated parts. The part numbers for the ICs are on the IC face. They can be purchased thru Hitachi or online at MCM Electronics.

Blue color on screen


If mostly blue shadow appears around the white objects means the cooling liquied is getting dirty and needs to be replaced.

My toshiba 42pw33p television show double image


If the convergence controls don't fix the issue then the convergence circuitry is most likely faulty. A Toshiba repair center will be able to get you an estimate for repair.

You may have to do the full convergence alignment for all three CRTs, as outlined in the service manual for your model. Do you have the full service manual for your set which outlines the alignment and convergence proceedures?
