Your symptom is that you have no picture but you have sound. And then the sound cuts out.
Sony Televisions have a circuit that blanks the video when there is a problem generating a picture. There may be something damaged in the video circuit, or in the video drivers on the CRT boards. Worst case scenario, you may have bad CRT’s in the set.
No matter which is the case, I would recommend that the set be looked at by a qualified technician.
This person could run some checks and lead you to a repair.

I could not recommend that you repair the set yourself.

There is a high risk of electrical shock when dealing with picture tubes and projection sets, as they have tubes that will hold a charge like a capacitor. This charge is around 30,000 volts.

I hope this information allows you to resolve this issue.

No picture but has sound


The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up.
The TV must be taken apart and tested before eventually replacing sustain boards.
