SAMSUNG Convergence Problem
It looks like blue convergence.
Look at menu, select convergence and see if blue top is bent down
on convergence adjust screen. Probably won’t adjust.
Some Samsungs have convergence IC’s on a separate
convergence board in the back of the TV.
Others have the IC’s mounted on the main deflection board. Either way
the board has to be removed to get at the dud IC’s and associated burnt
resistors.
You remove the appropriate board, determine if any resistors are burnt or
damaged, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's
and re-install the board.
Now you have to adjust it to look like new.
If the unit has not been misadjusted and everything is OK
now, running the auto focus may put the picture back to it’s previous stunning
quality as it was before IC failed.
If after Perfect Focus it is still misadjusted
noticeably, try the customer convergence adjustments.
Operators’ manuals are available on web through searching.
If convergence can not be adjusted properly, you messed up
chip install or resistors may be wrong value or open; or it needs major
adjustment.

Or try to the find the repairperson part of this website (on the Homepage) and
search postal code.
Maybe you will be
lucky and someone from your area is listed for Projection TV repair.
Most rookies doing this job will cause damage and not be successful. They will
pay double for someone to fix their mess or end up scrapping the TV.
It is not a simple task. It is more
difficult than batteries on a remote.
Good Luck
