this indications that you have a problem with convergence. first try to go into customer menu...setup....convergence. and see if the convergence will adjust.. if it wont then you have a problem with the convergence cuircit boards.

SOURCE: Hi I have a 52
This denotes a convergence problem. I would suggest that first you enter the menu of your TV ad try to do an auto converge on your set, if this does not work I would suspect that the convergence ICs have gone bad and need to be replaced. I would suggest that you have a qualified TV repair technician replace the convergence ICs in this set.I hope this helps,Shuttle83http://www.electron-age-technologies-llc.com

TO REPAIR... 1. Warning. this set can
generate leathal dangerous voltages even unplug do not attempt if you
have no experence with electronics.
2. Remove the back. there a number of torx 20 screws.
3. what you will see is a number of circit boards There will be one on the right and one on the left. the one on the right is the small signal board. the one on the left is called the power deflection board. it has a large black part with a big red or black wire coming from the top, this is the flyback.Next to the flyback on the right of it there will be three small rectangular componets tan or brown in color. these are fuses. the one in the middle is the fl231 fuse it should be labeled that right on the board.
4. getting to this fuse can be difficult. these two cuicit boards sit on a tray that is removable. to remove this tray it is pulled out and up. BUt watch the wires.loosen the wire tyes.
5 when you get the tray up the bottom side of the board can be accessed
you will now have to unsolder that fuse. one side of this fuse is under a plastic part of the tray. i have found the easest way is to cut away the plastic to get to it. if you dont want to do this you will have to remove the board. only remove half of the plastic brace
6. REPLACE FUSE RCA PART 259213 or you can goto radio shack and get a inline fuse holder and get the smallest glass fuse they have witch is .75amp witch is 500ma and all together cost about $5.00
7 RESOLDER FLYBACK CONNECTIONS or both ends of the inline holder simply heat up and add a little solder
8 reassemble set. make sure you examine the set for loose connections.
9 and remember "BE Careful'
