Can't converge red on the edges


Depending on the actual model number the set uses either one or two convergence chips and both would now have to be replaced.

Set as you know has convergence mode in customer menu and another in one of three hidden menus.

Blue and red wavey lines and distorted picture


Projection TV2_bing.gif 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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • 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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash2_bing.gif focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Look in users manual or internet you should find how to access service mode, this is different from regular setup CONVERGENCE, this involves getting into changing parameters to tweek convergence, even after amps are changed. These projection tv's are known for loosing convergence if bumped, moved and amps go bad in time.

Red Converance problem


Don't try to solve this in the service menu. The lines that do not move in the customer convergence menu will not move in the service menu. And, you can do some serious damage if you hit a wrong button while in the service mode. You have bad convergence output ICs. You can expect to spend $350-450 to have this problem fixed by a qualified technician.

Convergence settings


Key Functions
7,8,9 = select R, G or B
+100,0,PRE-CH = mute R, G or B
INFO = test/normal
4 = shifts from point to line, grid move
2 = restore factory
SOURCE = H/V select
ADD/DEL = Save
S.MODE = exit
MUTE = cursor forward
P.MODE = cursor back
Volume +/- = moves convergence left or right
Channel +/- = moves convergence up or down
1 = zero's all convergence settings (ugly!)
U/D/L/R = move cursor
SELF FOCUS = saves the convergence adjustment - do before exiting

Good luck.  I let a sub-standard service joint work on mine - they replaced the OEM chips with a higher wattage equivalent, and I've had nothing but problems ever since.
