Convergence wont line up


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

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

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common 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.

I have curves on the convergance screen


iF the convergence will not adjust (bowed or 3d etc) the two convergence chips need to be replaced.

If you can solder this is a very basic repair (board is behind front grill---see photos)

Fixya now has a Beta Site where you can choose specific experts to assist you.

I am there also as SD TECH

I can tell you how to get at the board and exactly what to replace/look for.

Parts cost should (from the right source) be well under twenty five dollars.

let me know if you have questions or wish to attempt the repair and or use the BETA site.

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.

Looks 3d


Do not open anything until you. Go to menu on your remote find convergence and press the volume button to the right go to manual and press right again. you should see a bunch of rectangles, now you should also see a set of red cross heirs press the #2 to move cross heirs up and eight to move down numbers 4 and 6 will move left and right and 5 will place the cross heirs back to the center once you have chosen the selected section to adjust line up the magenta with the other colors using the channel and volume buttons these move the lines up down left to right adjust all lines until they are white. i do not know how to switch from magenta to green or blue but this should get you started on the right track with out having to replace anything. good luck! if you figure out how to switch from maqgent to green or blue please post it so that I may adjust mine as well tahnks
