After being turned on for a short period of time, the picture is mostly sparkling green, making it impossible to watch a program. It usually starts after the TV has been on for a few minutes, but I have found no way to eliminate it.

Green Tube maybe trying to short out or you can try adjusting screen drive to the Green Tube by turning control down a notch, Sony had a bad run on these with alot of Bad Tubes.
Sounds like you have a problem with the green crt. That is the one I've most commonly seen fail first. Your tv has three picture tubes in it that can be accessed from the front of the set. The picture tubes(crts) have a filament inside the neck like a light bulb has a filament. Over a period of time tiny particles burn off and the debris can cause a short circuit from one piece of the filament to the other. The tubes are no longer avail. as a new replacement part but the tubes in your set can possibly be saved. One trick is to lightly tap on the neck of the tube with an insulated post or screwdriver handle. Right when you turn the set on and it goes green sometimes you can lightly tap on it, (the middle tube) and knock the debris free removing the short. If that doesn't work the tubes can be rejuvinated/cleaned using a machine found in most repair shops known as a picture tube rejuvinator. My experience is that this procedure should cost 100.-200. plus service call. Most service people will tell you that this is not a guaranteed fix, but 90% of the time it works and you can get years of more use from the tv. Good luck, Russmann.
2 blink-then 3 blink---------deflection circuit problem
2 blink-then 4 blink---------vertical circuit problem
******2, then 2 is most common---usually means one of the
fuses that protect the Convergence IC or IC’s is blown---set will detect no
voltage to convergence IC and shut down.
SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO
GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.
IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM
You need to take your tv in and have the picture deflector re-aligned. This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.
you have a shorted green CRT that is affecting the other crts the short is internat to the crt that leaves what is called retrace lines. if the set is more than three years old then replace all three guns.
i also have the same problem with the flashing green light for a while then a different red light starts blinking on and off around 5 times....and i replaced my burnt bulb with a new one...still no picture.
Colour will reset but then after a short period images tun green
