    I have a Toshiba 50H72 64" or 65" Rear Projection Television that looks that the image is in 3D. The red and blue colors are the main ones that show up. When going to the picture menu and going up or down on the menu, the text is okay until you move the button to the choice you want (like ant1, video 1, video 2, video 3, colorstream HD1, colorstream HD2, and ant 2). Then it shows up in red and blue. Also, the volume is distorted and muffled.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

How do you get it out of 3d what do I adjust, its not a 3d tv


This is an color projector alignment issue. Many projection TVs have a menu item in the video or picture setup that will produce a grid overlay on a black screen of Red, Green and Blue. You use the <, >, up & down buttons on the remote or the TV to move each color (one at a time) directly on top of each other and maintain straight up and down / left and right lines. Once you do this, the picture will be in focus and there will be no more colored "3D-like" ghosting. If you are unable to move the colors far enough, there may be an issue with certain integrated circuits inside the TV that can be challenging to remove and replace. More make and model number for your TV would be required however.

I'm getting an overlapping of two colors on the screen.


Hi,
It is common problem with rear projection tv and 3D type picture problem occurs due to failure of convergence output ICs, replacement of convergence output ICs will fix the issue and tv will again show correct converge picture as before.
Let me know tv model number written on back of tv if you want to fix tv by yourself as it needs soldering parts in circuit board expertise and if you feel uncomfortable working in tv circuit boards than local tv repairman will do this job for you.
Thanks.

You have a Convergence circuit failure. The Convergence ICs probably need to be replaced. It should be done by a professional due to the adjustments that may need to be done in the factory mode after replacing the ICs.

Samsung 42'' HCM4215W image looks like it's in #D


Ill have to look up the part numbers , but it is a common problem caused by the convergence board at the back of the device. replace the TDA*** for the color that is faulty and the problem should be solved.
After replacing the TDA*** you need to adjust the convergence again and perform an auto-fucus and convergense adjust again

Poss. convergence problem with Hitachi 53UDX10B Ultravision


You have convergence problem. Either bad connections on ics, ics are bad or voltages to convergence circuit are missing. There are no bulbs in this set. 3 picture tubes,red,green and blue produce a picture than when alighned(converged) correctly on top of each other gives you a color picture.When not you get the effect you are describing. Frst you can try the magic focus in the menu.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.
