Re: No sound

1.Disconnect the hdmi and see if you have sound on
tv channels with antenna
2.If you have a dvd player hook it up,see if it works,if
not plug the video cable into one of the audio sockets
should hear buzz if audio amp is working
3.if you dont have sound go into menu and find
center channel input and toggle it to on that should
turn on internal speakers

Re: No sound

Hi are you sure the mute button isnt stuck on your controll if this is not the case then it could be on the circuit board.
Have you tried changing the sound mode and see if this changes anything.
The only thing you can do if it is a board problem is buy seperate speakers that will plug into the audio out put connectors doing this will let you know if it is a controll or setting problem also if you try external speakers then you would no that it isnt a controll problem if you got sound through the external speakers then the chances are that it is a solder problem if the solder had gone on one speaker you could eliminate that as you would know where to look but as it is both the speakers, Im basing it on that you are using the speakers inside the telly and not external ones if you are using extra speakers unplug them and just try the telly ones.
So basing it on that you are just using the internal speakers then it could be a solder problem on the board where the speakers plug into.
It could be something as simple as a resistor gone or going these are cheap to buy but i dont sugest fitting yourself unless you have relevant testing equipment and a good knowlege of soldering.
So first i would try changing sound modes on the telly if this dont change anything try pressing mute button just to make sure that the controll and all its functions are working properly.
But after this if it dont solve your problem then you could either buy external speakers as this might solve your problem but if you want the telly working as it should be you will need all equipment and to be able to read a spec sheet and be able to follow cicuit diagrams.
Let me know how you get on and what you want to do

There should be a HDMI input on the Sharp Aquos with audio inputs next to it. Run a audio cable from the audio out of the satellite box to that audio in next to the HDMI input.

Setting up sharp 46

Try to isolate the problem.

Try plugging in another source such as a DVD, is there audio? If yes, problem may be with the optimum box. If no, most likely a problem with the TV.

Also, if you are using HDMI with the HDTV box, make sure the box is set to output audio through HDMI.

Sharp Aquos 46"LCD

You might want to try a system manufactured on the last two years most brand new components will support HDMI connections, of course the price will be a important too but you can find systems for about $200. Any brand of your liking will do just look for the HDMI logo on the box or the front of the component. If you consider to keep your amp, try to find a HDMI to AV converter I would not recommend to do this due to the fact that they are pricey and hard to find on top of that think about the loss of quality on your audio and video (personal experience).
