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.

If the tv doesn't reset after being unplugged awhile, there's an internal problem, and the unit will have to be serviced. Make sure the cable input isn't loose, and that the cable cord is good. Aside from that, there's not much you can do. Some cities have mobile TV repairmen that will service the unit in your home, and it's much more convenient. Look in your Yellow Pages under TV Repair.
Good luck, and hope this helps.
