Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

Mitsubishi VS-45609 Blue layer is distorted and seperated

The blue layer of the screen is warped leading to a seperation of the viewing image. I was wondering if anyone had any suggestions, I've heard that it may be a convergance IC. If it is I would like to know what part I should order and maybe where I can find it on the TV board.

Thanks,

Double_G

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

There is a seperate microphone to do that. Usually when the CCD imager is bad it cause a white screen to appear or the colors are distorted in the view finder.

I would take it into a camera shop and see what they say unless the battery hasn't been replaced recently.

since two colors are affected I would suggest checking the solder on the convergence power supply. If the solder is good you will most likely need a new power supply. The power supply board is the one without all the heatsinks next to the convergence board
