Question about Sharp LC52SB57UN LCD TV
If both are lit and blinking then the tv is in protected mode - the protection system of the power source has detected that a part has failed and it's acting like a short so it has shut down the power source to protect it and the rest of the tv from further damage.
The only way to find out what part has failed is to open the tv and have the voltages on the power source verified - the one that is near to 0 will be the one that has triggered the shut down. Follow it and you will find the failed part. You need at least a basic experience in electronics to do this job, if you don't have it then call someone who has. And keep the tv unplugged from the mains, it will limit the extent of the damage.
