Hello & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of any issue you are having with your system.
To help you with this issue, may I ask:
1) Can you CONFIRM the FULL Make (brand) and Model Number of the system you are working with?
2) The AGE of the system?
3) WHEN this issue first began (or was noticed)?
4) When you mention you entered a CODE (after pressing MENU) and scroll, were you actually able to SCROLL, and see the ON or OFF options?
Please use the REPLY box below.
I see it has been a few days and I haven't seen a response on this page, so I just wanted to follow up to see if you have any more questions concerning this issue OR if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
