Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
This is a paid support service for information and advise on your question.
Do you have any other remote (cable/satellite/universal) that has been programmed to operate the amp in the past? If so, is that still working?
Do you need more help with this?If so, simply reply back on this page.
Please note: You have already paid your fee to the site; I'd like to help you and provide value for that fee, but I do need to communicate with you here to do so.
