that chassis for sony is the DA4 chassis and they had a big problem with regulator failures in the main power supply. primary and secondary power regulators the location numbers are IC8002 and IC6501 i believe the part number from sony is MCZ3001DB you must get the part number that ends is (DB) or you will not reliably repair the tv. the sony part number is 6-705-810-01 they are going to cost around $20 each because they are the good parts. they are going to be about 20 pin ICs and you will just need to desolder old ones and resolder new. they will be on the board on the left looking from the back about middle of the board on the left hand side. good luck!!!
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.
There may have been some problem in the horiontal transistor. Also, Check for the zener diode that controls the supply going to the flyback. It might got busted due to the sudden supply surge.
