Sony Fd Trinitron KV-32FX68E, stanby led blinks...

Question

I have a tv sony fd trinitron model KV-32FX68E 32''. When i swich it on, there is no picture or sound(black screen) and the the stanby led blinks twice continously. As i read somewhere, perharps there is a problem with the power supply. Is that right and what can i do ? Can i fix it by myself or i should send it for service? For the seconf option, is it worth to fix it or to buy a new one?
