Just got my Sharp LED 40" 810 series, connected it last night with my Rogers HD Box (Explorer 3250HD).
Connection:
3250HD box was connected thru composite input of the tv.

There are some audio issue on the following conditions:
- when i change channel from the HD Box, distorted sound occur, like banging a drum twice. this happens on every channel right after it switches from one channel to another.
- hissing sound all the time.

can somebody share their expertise about this issue.
HDMI input from DVD works fine, only happens when i am in TV mode (composite source from rogers hd box)

Shouldn't you be connected via component video?

You don't stated how the audio is connected - I assume via analogue audio. Also make sure that the audio in the STB is set to "fixed" not varible and that you use the TV to control the volume. Turn down the volume on the TV before you change to "fixed". You can programme the remote to control the TV's volume - covered in the Remote's operating manual, if it isn't pre-programmed.

thanks for the reply.
Sorry, yes video is connected thru component video.
Also the audio is connected thru Analogue Audio Cables .

Yes, i did that already, set it fixed.
But still those two problems are there.

did i miss something? i am not sure if this is tv related issue or the hd box issue.

hmmm. Hissing is usually low signal to noise ratio fixed by setting audio to "fixed". Here's another list of things to check - unplugging/replugging cables, swapping audio cables for a different set, etc: Make sure you've got the audio cables connected to the correct inputs/outputs. Sometimes people will connect an analogue audio cable to the coaxial (output) connection on the STB by mistake and get hissing.

Try connecting the cable directly to the TV, do a channel scan and see if you get the noise when switching analogue channels there without the STB. Have you done a cold reboot of the STB? You may need to swap the STB. If it's rented, get a 4250HD and use HDMI...
