My display is arched on the top and bottom of display on my sony kp61hs10. Wanted to know a solution to fix this issue.

Sounds like a convergence problem--see attached pictures--if so let me know model number and I will offer advice.

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Your power source seems to be the problem, you will need to replace that part.

Sounds like you have a problem with the high voltage regulation or the power supply. This condition is called "blooming" Stargazer
