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.

There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.

Hi it just comes on once and goes off as I thought it would flash, so what happens is you have the orange stand by light on then push the switch you hear a click,red light comes on and goes off, and it does this all the time I hope you can help as it is a lovely tv
Count the number of times the led flashes . This is an error code and will help diagnose the problem.
