Sure - but you need to find out what the new error codes stand for and be guided accordingly. You might want to check on the Sharp web site. Your t con board might also have gone south.

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://electro-medical.blogspot.com/ If blinks continue without any pause, the main board is faulty.

is it connected to anything??

Well, sir, you can't. Not unless you know someone, SHARP does not deal to any store or supplier with replacement screens. Besides, the replacement screen, which would include a new LCD panel, control board, plastic screen cover and the like would probably cost more than a new TV in the market.

Does the set get good air flow in the back, sometimes these sets get too hot and cause this problem, you may have to order service manual

yes , the problem on ur tv is the main signal board , when this board goes bad the opc light blinks , i have fix like 20 tv with this problem , now to order the right board u most look at tuner inside ur tv and get a 4 digic number follow by word main , by replacing this board would fix this problem on ur tv

It possible but unlikely that your speakers are bad. First what you want to do is try to see if its not the source. IE cable, dvd, bd or video game. Try replacing wires.

If that fails, (Depending on the set) replace main board. If its a slightly older set main and terminal. I don't have access to sharps website at this moment to see the exploded view of this set.
