Hi everybody! 

I have obtained a OBXA 120 patches model recently. It was in full working condition ( I saw the demonstration by Skype). But after it finally came to me I ´ve noticed some problems:

1. Two keys are stiffer and are not working

2. Entire memory is wiped out - there is only noise with some modulation (battery shows 3V and is not leaking, manual mode works.)

3. I can ´t write any patch to the memory - instead of writing it goes to the chosen "noise" patch.

There are no apparent loose components or connectors. Everything seems to be in place. Where would you start the diagnostics Thanks for any help.
