It sounds that the main system control memory IC has damaged. Do a reset to this set and check. Refer its user manual to know how to make it a hard reset.

SOURCE: Sharp LC-52D62U HDTV won't tune-in channel 21.

I finally got Sharp to repair the TV. It was under warenty but they said if the problem wasn't with the TV they were going to charge me for the service call. I told them I wanted a new TV. They sent the tech instead of a new TV. He replaced the turner card and it worked!! Now I get all the channels as well as channel 21.

SOURCE: my sharp tv model 20H-S60 remote input button is not functioning.

Welcome to Fixya! First thing would be to Disassemble the Remote and Clean the Pads and Terminals. Inspect the Board for Breaks in the Circuits. These can be fixed Easily with Solder or Even the Contact Pen that Radio Shack Sells. You can Draw the Circuit Back on the Board with it.

SOURCE: Sharp Aquos HDTV Failed to receive broadcast

I too have this issue I beleive what is happening is the integrated tuner is not locking on to the channel because of a weak signal and then sending that error message . I am going to replace the cable from the splitter to this tv and see what happens. I have another new tv just installed from that splitter and it has all chanels. Remember to RE- run the locate all channels after anything is done to the cable splitter etc.

When my sharp lc 32sb220u is turned on, my direct tv remote will not change channels. this just started. Nothig was changed. after this, i did change the direct tv box and it still would not change...


That remote has to work / it is a direct tv issue since it is their equipment that you are renting and it is supposed to work with your set..
Did you make sure that the batteries in the remote are good? that the remote unit itself is good ( Use digital camera or am radio to test out - see google)
