I just purchased a 70" Sharp Aquos LED TV. The problem I am having is when I turn my TV on after about 1 to 2 minutes 6 icons appear on top left corner of my TV screen. When this happens it seems to lock my functions on my controller. The only functions I can use is changing channels and turning my TV on and off with power button. Can anyone out there please tell me how I can remove or turn off these icons from appearring on my screen. Thank Yoy, Desperation.

Usually the settings can't be turned off and the audio settings are searching for whatever is being outputted from the program itself whether mono or stereo. It is nuisance I know.

Usually the DISPLAY Button on your TV remote will toggle through several different functions: 1 sec, 5 sec, Always on..... Press button until display on TV is off. Or see if there is an ON SCREEN DISPLAY portion in the TV Menu and turn it to off if you have not checked that already.

1. By View your DVR, Do you mean you can actually see a picture?
2. By "Switch Channels", are these channels being tuned by the TV Tuner?

Your LCD Panel is OK Since you have a Picture (input display in right corner)
If you can see a picture with your DVR, VCR, DVD or any external source then your TVs Video Processing is OK....if not you will probably need to replace the responsible PWB for this function
If you can see a picture with the external sources and only the TV's Tuner is not showing Video, The PWB responsible for Tuning within the TV should be replaced.

Also, if all problems are associated with only the DVR (I assume this is Sat or Cable), then it is most likely that this device is not functioning properly. Possibly lost signal or deauthorized.

did you check the sleep mode on the tv?
