How do I fix my 32" Sony Trinitron television?

I don't know what is wrong with my tv. The video no longer works on my tv and the standby light is continuously flashing.
Before you would turn the tv on and it would be a few seconds until a louder noise and then the video would work. But now it is almost a click noise I hear but nothing afterwards.
I don't know whether in fact my son did touch something to make this occur as I have looked at most sites that talk about the standby light flashing as a self diagnosis tool. But they are continuos flashes at regular intervals which everthing says is not a problem and it is simply in standby mode. But I cant get the dang thing out of it. Anyone?
