issue with Flashback 1 – warning tone?

issue with Flashback 1 – warning tone?

Hello All- I searched this forum no no avail so i thought i would post a question here.

I have a flashback 1 that is about 4-5 years old now. It basically works fine when connected to a power supply until about 20-30 minutes every time, then it starts emitting a signal tone no matter what setting or level – basically becomes a tone generator. If i unplug it from its power supply and let it sit for a minute it will work again , but for only another minute or so until it starts generating the tone again.

I have updated the firmware and changed / tried different power supplies ( all correct) and even tried using a 9 volt battery and the problem still persists.

Let me know if you have seen this before or perhaps have solved this issue, it would be greatly appreciated.

Thanks and Cheers-
