Thank you for the reply and info about the battery

I put a 32k ram chip in there but the problem still persists. However I believe the problem is due to something with the RAM since I get the same messages when there is no RAM chip in it; except it takes a few moments to occur when there is a chip in it.

Any other help would be appreciated, I can make a video if needed. Also considering taking it to a pro...

The issue is that, if I let it sit and rest for a bit, it starts up fine and works great, until after about 1-3 minutes when all of the function become inaccessible. AKA it shows "0" for preset, and it is unchangeable, as well as all other functions show "oF" and I cannot change it. This will happen immediately if I just switch it from on to off.
