SOURCE: No POWER
How many times does the POWER led flash per second? (Dont worry about the OPC).
1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit
If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)

This screens are all but impossible to replace.You only have a couple of options. 1. Buy a replacement screen for the television manufacturer 2.Find the same make and model of television with the screen intact and purchase it. This can be done by watching websites like e-bay and craigs list for these items. You can go to the websites and use their search engines with the brand name and model number tofind the televisions or the parts that are for sale. If you can find the part number of the lcd screen. You can try to locate the lcd screen maker and buy the part from them. By far the lowest cost alternative is to find a television with other problems, that is not repairable and buy it and use the parts. You can also look for it in local newspaper ads and yard sales. I hope this information helps you with your problem.
