Hello, When first turning on the set, there is too much green color. Black and white pictures will have a green tint. After the set is on for about a half hour, the overwhelming green subsides. Is there a known fix for this and is that fix expensive? Thank you....!!!!

In the back of set you have a red green and blue gun.
two or three problems with sony on this.
sum times the green gun will go intermit.
by gentely taping the neck of green gun while set is on, and you see corection, you need to replace green gun.
in others we have found bad soldier in the HV section of the flyback.
and sumtimes its due to louse conectors going to the HD input in back of the set.
hope this is of help to you.
this is a common fault adjust the little black box in front behind the small wooden cover. you will see 6 controls don't adjust any of the top 3 only the bottom knobs 1 for each color. slowly back the control counterclockwise turn the set on and wait untill it shows a picture, slowly adjust the control for the color in question utill the color balance is correct- black and white with the color setting turned down all the way with the user menu when balance is ok you are all set.. turn the color back up with user control. rtepeat process if needed.
When ever a tube starts to short or is shorted set always will have over bearing drive lines then shut down like RED if it was bad, set would come on long enough for red lines across set then shut down this is the same with all 3 tubes.Also if you think it might be green tube disconnected green CRT board on neck of green tube if set comes on and plays then it is green tube do all 3 tube this way one at a time this will tell you if you have other problems.

. If you see your symptoms you have a problem in your convergence amplifier circuits. Typical Sony Convergence repair requires disassembly for replacement of 2 ICs, sometimes a fuse or 2, then TV is like new.
It is much more complicated than changing batteries on your remote. Many consumers try unsuccessfully to do a convergence repair. I recommend finding someone competent to do it for a reasonable price. Typical repair shop charges may be from $400 to $650.
If you are in the Calgary area, call me. More reasonable rates.
It looks like your green CRT is malfunctioning. You should try to see if the voltages are correct on the socket of the green CRT and check the high voltage on the green CRT using a high voltage probe. Use a schematic diagram to reference these voltages to.
I am positive that the problem is the green CRT or the circuitry leading to the green CRT. Please use caution when checking these voltages.
