The problem with your TV trinitron wega is at the color adjustment section. It is located at the color board mounted at the back of the picture tube. There are variable resistors that represents the color pattern in the picture tube. Adjust the red color to low level to lower the red color.
yes. you are not getting green. sony has a circuit that if the picture is not perfect, it will shut off. two solutions....one, take off back and with the tv on, tap pretty hard but not hard enough to break it, on the neck of the picture tube with the plastic end of a phillips screwdriver. this will shake the old sediments in the crt. the tv will probably shut off if you do it right. tap harder and harder many times. fixed. two, rejuvinate the picture tube. fixed. easy
It could be a dry solder joint on the base socket pcb. Try resoldering the base socket, and try for dry joints on the main board also. Check if the rgb voltages are steady on the crt driver transistor bases.
If it is truly a 52 inch standard projection set (you have it listed under 32V420T which is not a projection TV) and your 3 colors (red, green and blue) are no longer lining up and are all curved on the sides, then it means that your convergence power supply has stopped working. Post the actual model and chassis number and a better description of the picture here and I will be able to assist you further.
