Hello
Check the speakers first. Get this set connected to an external audio amplifier device, such ans an amplifier or so, with its audio out connections at the back of the TV with audio in connections on the back of the amp, and listen whether you can see sound from the external amp. If you can hear sound from the external amp, and not with the internal speakers of your tv, either the speakers may have damaged or it audio output IC had got damaged. if so you have to replace the IC or should replace the audio card o your tV, if the IC is not available at local electronic spare part market.
If you can't hear any audio by external amp, as it has been connected as stated earlier, the mother board [main board] of your tv has the trouble. There is no repair to this digital board, and it should be replaced as card basis. OK.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
