Just got an 2002 Sony projection tv. when you turn it on, the screen gradually goes green. is this worth trying to fix

If the lamp light is blinking, then the lamp needs to be replace. If the Power/Standby light is blinking, then try 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 the TV needs service.

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.

Could be the video driver for the green CRT, HV Block or a bad CRT.

These sets have weak picture tubes, this may buy you some time. It is not worth changing the tubes in the set. The cost would be more then its worth. Try these adjustments until it completely dies. I have the same set.

Green and Red guns seems defective and requires replacement.
Both guns (CRTs) are no longer available so TV has no worth to repair.
