Green screen when tv is turned on with just a shadowing of the show visible on the sceen, volume is ok. Could an electrical surge cause this problem? Easy repair yes/no? Cost?

Could be a bad CRT, a bad or poor connection on the CRT drive board/CRT socket, or maybe the drive from the RGB circuit. is defective. Your going to need to swap out one of the drive wires to see if the drive and crt is good. If nothing changes, Im guessing the CRT could be bad. One more thing, Check the RGB drive voltage, I have seen this being low in this model of set, and causing this problem. Turned aout to be a bad capacitor in the sweep power supply. If you have no solid state repair experience, play it safe and let a trained tech assist you in this repair. Good Luck, and keep us informed of the repair on this TV.

Thank you for your quick reply.
What is CRT AND RGB?
If this helps a little more before the green screen the tv. would turn on red then just days before turning green, the color started fading in and out from ghost-like to a nice picture.
CRT means Cathode ray tube, another name for the picture tube. RGB is Red , green, and Blue.
Larry- UPDATE ON GREEN SCREEN
TV IN THE SHOP AND BACK HOME SAME DAY. THE PROBLEM A CRACK IN THE PC CIRCUIT BOARD TV WAS ALSO CLEANED AND COLOR ADJ. TO FACTORY SETTINGS. Now even the clock holds the correct time of day weeks before going green the time was not holding .
Cost $50.00 to diagnose - $90.00 Rapir/Labor/Parts - Total $140.00
