When i turned on my tv this morning, no sound was coming out. It was fine last night and i cant understand why theres no sound.
Any ideas anyone?

Unless you know Solid State Electronics, there is nothing you can do. At best, You could unplug the TV, remove the back cover, slide out the Circuit board, and check the fuses. They will be at the front of the Circuit board, left hand side. But in all likelihood, it is not just the fuses, the Power Regulator STR would also be short circuited (happens often in SONY TVs) and so it is best that a professional technician have a look.

Since the you were vacuuming behind the set before this happened, I'm going to assume that you unplugged an input. Check the wiring, not just on the back of the set, but, on the back of the peripherals (DVD, Satelite, cable box, etc.) If wires are connected, then, take a component, such as a VCR or cable box and hook it up to the RF connector (AKA the cable connector) and run it on channel 3 or 4. If you have sound, then, you have a configuration problem and need to rewire your set. Hope this helps.

Sounds like horizonal output transistor could be over heating. There could be other problems. But I would start there. You can find the part number on the schematic inside the set. If you change it yourself don't forget to use the included insulater. Part should cost between 15 & 20 dollars. You will need make & model # of set at electronic parts store.
Diagrahm inside set will show you location of transistor.

Sounds like a failed vertical amplifier circuit. This is normally primarily contained in an integrated circuit mounted on a heatsink.
There are other possibilities along the line but the one above is the most likely.
Now all you need is a TV repair shop that is still in buisness.
