Toshiba theaterwide tv turns on and off on it's own and picture is messed up


I presume you unplugged set for a while and plugged it back to see if problem clears (allows set to reset).

If whatever picture you see looks 3d or colors skewed that is convergence problem.

Tv is 3D and color is messed up its a Philips projection tv


What you likely have here is a convergence problem and I THINK you will find this model may have actually been made by Hitachi(they made them one year around 2001) and if so it is a better set than the Philips sets.

It depends on if you can do it yourself---If you look inside from the back to the right and see two black IC chips mounted on a large metal sink with fins and they have the STK392-110 number on the front of them----THE SET WAS MADE BY HITACHI.

iF It is a Hitachi set the parts cost will be under 25 dollars total.

Confirm which chips are in YOUR set (they are black,2 1/2 wide and 1 1/2 tall) and I will tell you what is needed.

My picture is messed up. Its kind of unclear with


Projection sets have two very common problems.

The first common problem is convergence


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. This is called convergence.

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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

I have a 52'' Magnavox Projection screen tv and the colors are messed up. The best way to describe it is that it looks like your looking at a 3D movie without the glasses. Can you tell me what's going on?


The most likely cause is shorted convergence chips and possibly a few pico fuses.

Your TV most likely has one or more 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.

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.

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.

Problem with the picture


You need to replace the convergence ICs in this TV set. If you know how to solder and work on printed circuit boards and can follow a circuit diagram, this should really not be a difficult thing to do. If you do not have ALL of these talents, play it safe and call in a pro to assist you in this repair as this TV set is NOT the place to be experiementing around inside of. Good Luck
