For sure it needs a proper and safe diagnosis by a qualified and experienced
technician in order to know what the problem is. The technician should
start troubleshooting the picture tube drive and bias voltages, the AKB
circuit, all the way back as needed.

There are lots of possible guesses. Were you to do some basic research on
Google Groups you probably will find many of those guesses as well.

I have a 32 inch Sony Trinitron. I do not know the model number, it is
about 9-10 years old. Anyway, the problem I am having is that the
picture keeps blinking on and off. When you put the TV on, it starts
doing it really fast and it takes about 10-15 minutes for it to stop
doing it fast. Does anyone know what the problem is?

There are too many guesses. The tech would have to start by checking the CRT
emission, high voltage regulation, power supply, and the AKG circuit
performance to start with.
