sounds like you have a cable connection problem make sure your tv is set to dtv signal in the menu screen. when you scan the channels should be displayed as 12.1 or 8.2 not just a single number if the digital channels are programmed correctly then change the cable coming into the tv from antenna making sure that it isnot crossing any power wires good luck and hope that i helped

Sound but no picture


You will need to perform a factory reset/INIT on your television. Call 877-332-7867 for assistance. You will need to complete a case file with the customer service representative first and then if he or she cannot walk you through it you will need to speak to an aquos advantage dispatch representative. You can call anytime between 7AM and 9PM CST but the dispatch representatives go home at 7PM CST.

Sharp aquos 42"


Check the settings in the TV set for HDMI sound on the input of the TV that you are using. Try another HDMI cable. It may be defective.

It is also possible that there is a compatiblity problem for the HDMI sound between the TV and the computer's sound protocol.
