Television and Home Theater

Help, My sony TV just went dead and I don't know what happend. When I try to turn the tv on it doesn't do anything. The little light in the front just keeps blinking. It is supposed to fo that and then cut on. I don't know if the power supply went bad or something else. If someone can help me out with this I would appreciate it very much. Thank you in advance.

i have a 27" daewoo and all is good except the sound, some time it gets sound and some times not before the sound goes away it starts to get fuzzy before its gone, so id like to know if u think its the speaker or the tv itself,and is it possible for me to fix it myself.
thnx
