Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:

http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=3229

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips.

Typical Symptoms

1) Convergence menu does not work for one or more colors.
Such as: Red moves up,down, but left or right fails.

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com

Hope this helps :)

Converence

green is fixed so you have to move red and blue to green.
by using the remote you may find a simple converge function and open this and using arrow keys move the blue or red first to center of screen, repeat for other color you should see the lines moving toward a a white center point.

if the lines do not move with remote try manual ...menu on the set. if still no movement you have a problem on the convergence board and need a tech to fix.

A service manual will explain complex convergence to the detail .
but this might take hours to get it right.

Try soldering your convergence amplifier ICs. Sounds like it has a bad solder conection on the ICs. Check them good with a magnifying glass. Hope this helps you out. Let me know.

No color

You're using YPbPr (Red/Green/Blue Component) cables, right? Make sure you've got them in the right inputs and that the cables are FIRMLY attached. (Sometimes they seem attached even when there's a half-inch or so of space still)
