Try lowering the brightness and contrast. Sounds like you are overdriving the picture tube. Green gun in picture tube may have a shorting element; if so no fix for that other than pic tube replacement.
Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider
Isolate filament voltage from CRT,i.e. unplug
Crt socket from pix tube.Measure filament voltage on CRT PCB.If present,suspect bad pix tube.If missing,solder any/all connects in
filament circuit,meaning CRT board first then
Sounds like you have a problem with the blue gun in your picture tube or its drive circuit.
You might remove the back cover and gently tap on the neck of the picture tube using a plastic
screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem.
If this is a projection tv you have three separate tubes : red, green & blue.
you'd need to tap the blut one.Gently!!!!
the picture tube on your TV set is exausted. Please contact your nearest Authorized Sony Service for further help/advice.
After all, Sony is a good choice. The next TV set you buy could be one of Sony-s Bravia LCD.
It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.
You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
