It looks like blue convergence.
Look at menu, select convergence and see if blue top is bent down

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
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.

It is not a simple task. It is more
difficult than batteries on a remote.
