Its a convergence problem. You can get complete parts and instructiosn for this fix from TvRepairKits.com. They put together a kit for this. I used them for a convergence problem recently and they helped me fix my set.

Possibly magnetic interference check and see if there are any magnets such as a speaker magnet near the bottom of the tv - if so move it away from the tv this should eliminate the arch. could be at the back or the front

Green hazy upside down arch of color across the screen


Your convergence board is in need of reworking on a component level or replacing the board! And you will most undoubtedly need to resolder the vertical IC and all ICs mounted on heatsinks on the power supply board. This TV is showing its age. You may choose to repair and that may last a year more or so! Good Luck and thank you for asking!

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck
