I have a magnavox projection tv and all three colors seperate on the screen. How do I fix this?


Thats usually a convergence issue. Most phillips and magnavox ear projections use the Phillips DPTV305 - DPTV345 convergence repair kit which contains the parts and the CD with instructions for the repair. The kit is available at www.tvrepairworld.com

Sitting here watch tv and suddenly the picture went warped and discolored. Picture looks like the colors are seperated. blue green and red.


Your TV has convergence chips that need to be replaced by a tech. These keep tour red green and blue lights in sync with one another in order to give you a sharp color picture. When they fail your colors seperate.

Looks like some kind of color seperation


Three d looking etc means a convergence problem.

If you go into the customer menu and select convergence and then advanced look to see if blue or red are skewed and or will NOT adjust in some area.

If this is the case I have start to finish and step by step instructions for this repair that I can post here for you.

Total parts cost will be under 30 dollars from a seller I use on EBAY.

LET me know if you have any questions.

Fuzzy picture and dark picture and color seperation when hot.


The colors seperating is a convergence problem, as far as being dim this may be related but the TV likely needs service adjustments.

convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Green color seperation multiple images convergence will not fix


Your TV most likely a convergence 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 are some photos of convergence problems.

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.

Three colours don't converge


Shrink, the convergence circuit needs to be repaired, Until someone gets in there and takes a few measurements it`s hard to say what the cost will be, may just need to be re-soldered, good luck, BMW Rider

Mitsubishi projection tv


I have a similar problem. I have tried to fix the convergence via the remote and that has not helped. My three colors are separated and the edge of the picture is bent in toward the center. I am going to try a hard reset but i suspect the convergence IC are fried. Since the set is not HD, I will probably replace it if the hard reset does not work.

Green colors are seperated from rest


You might have a bad green convergence output IC either loose from the circuit board or open internally OR shorted. Stargazer
