SONY WEGA KV27FS120 WON'T TURN ON, LED BLINKS A... My set is only 2 yrs old, it worked fine, but

Question

My set is only 2 yrs old, it worked fine, but one day just won't turn on, I don't feel any magnetic force on the screen, the led blinks a few times, but will not turn on, what's wrong? I have a KV-24FS100 with the same problem. Any help would be appreciated. We are now having the same problem as above with our Sony Trinitron KV-24fs100 TV, please let me know what we should do. I didnt know if it was something easy to change out or if we should take it some where to get fixed if in fact it is fix able. Thanks
