Schematics come from the sony distributer, I think you have a BG1S and what you ask suggests you should not try. But if you proceed, the flyback is common in this as is a blue ceramic capacitor across the line output C820 (330pf 2KV) change to a 6KV type. Other than that how do we know where to send you if we dont know where you are. This is a PAL set distributed over Europe, Australia NZ and S Africa.

I am in Perth, Australia

The problem is that my TV is making a non-stop clicking noise (metallic noise) when turned on, (No picture and sound), I've checked the board for bad solder joints and everything seems ok!, also there is no flashing stand-by light.

rrobor what's a BG1S????

A BG1S is the chassis the distributer of Sony parts in Australia is Speedy spares Macaulay road Kensington Melbourne vic 3031 Phone 03 9376 1333. "Go" in Queensland also have parts they say will work with Sony but I was never game to try. The clicking is a short on the B+ line it can be the flyback transistor and transformer which is common or the blue capacitor I stated before. In this instance Im sorry you really are out of your depth, the transistor will be about $20 and the transformer to me about $90 postage about $10. You want to buy it the lot about $200. Get a quote, there are a few good guys in Perth, try Mundaring TV.
