After a power outage,the tv wont turn all...

hello, if you have a blinking light this means theres a voltage drop or failure causing a circut fault some where inside, you need to find a service manual for your set or have it checked out by a tech. there are high voltages and live circuts inside so if your attempting a fix on your own be aware of this and get a service manual it will tell you according to the blinks whats the trouble or what part to replace or service. hope this helps.
