Try running the optical TOSLINK cable from the TV to the receiver. If the TV doen't have a digital optical output, then try going into the menu on your cable box and setting the audio output to the digital optical out. Also check your TV menu and make sure NETCOMMAND is diabled. Some of your newer HDTV have Netcommand that allows the TV to control other devices through the HDMI cable.

When the tv won't scroll to the HDMI inputs, it means that the tv does not detect a signal on those inputs. This either means the tv has an issue and can't receive an HDMI signal(very unlikely) or there is no signal being sent from the source(converter box) The first thing I would do is unplug all output connections from the box except for the HDMI output and see if this gets rid of your problem. If not, I would be more inclined to think you have a problem with your converter box than with your TV. You could also try using the HDMI ouput of a DVD player if you have one.

I got the sound on my LC32D6U fixed for free. Even though the TV is out of warranty, Sharp considers it under warranty for the sound problem. The number i 800-237-4277.

There are a number of things to check here:
1) Verify that the resolution on the PC is set to a supported level for the TV. Usually the TV will show "no signal" if the resolution is out of range or the message "out of range" will appear.
2) You don't indicate whether you are connecting to a desktop or laptop. If a laptop, you may need to turn on the external monitor. This is done by using the function key and either F5 or F6 (the key should have a picture of a screen on it). Hitting this combination will toggle between the main screen with.without the external monitor.
3) Verify that the TV port is selected correctly (AV1,AV2 etc)
4) You will need a separate cable or the audio regardless of the system type. Also verify that the audio cable is in the corresponding audio input jacks for the video option selected.
If you have completed the above and it still doesn't work, please post the details about the computer being used and the exact cable setup that you have and I'll check into this further.
