Do a factory reset to this set. To do it, you have to enter its service mode option. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/ Service mode entry, adjust and exit procedure to many popular brand TVs are given.
Try the main resets in the back by the a/v in and out jacks. If this does not work, call Sharp Customer Service and tell them that you already did the resets. There is a known problem with a heat dissipation pad and they will send a repair tech to replace the pad for free, even if you are out of warranty. At least that was the case for my LC-32D6U.
That message is presented when a selected digital channel is too weak to decode. Let us hope that something was accidentally changed:
Is the channel legitimate? Is the antenna/cable still connected (to the Digital input)? Go into menu - setup - channel setup. Is the selection of either cable or air channels correct for your situation? Use menu - setup - Antenna Setup-DIGITAL to examine the signal strength. Is there nothing at all, or is it just a question of strength?
Odds favor a change in channel setup that you would not have made intentionally, or a simple physical problem (input cable, etc.). Start from scratch, and check the settings and connections you originally made. Hopefully it will be simple and cheap!
There is a hidden menu. Press the "MENU" key and then press "991". You now see a new menu labeled "Factory". One of the settings is:
EEPROM Init. Selecting this supposedly resets your television and erases almost everything you've set... so don't do this casually. And don't press anything until it is done. I'm actually afraid to try this since my set works. If this fries your set, you're on your own.
