Poor sound quality


Hi, I sent an email regarding the issue to OnCorpus (the company who makes ProScan)

This is what I got back:

---------------------------
Thomas,
Follow these steps to correct humming issue:
1. Turn tv on
2. Input mode should be tv
3. Turn volume to zero
4. With remote enter 9 8 7 6
5. A menu will appear on left side
6. Arrow down to backlight and with right arrow key move number from 81 to 83, press menu button twice,
7. Turn up volume and listen if hum is gone.

I can't confirm if this works at this moment since I don't have access to my TV.
