I got this alarm a couple weeks ago. Just restarted machine and everything was ok. Thats not working any more. Getting asterisks and random numbers like when the battery goes dead.
Tried the OP 12 reset procedure that I used the last time when the battery went bad. The parameters aren't holding between restarts. Also tried unplugging battery for a while.
It gets more weird. When I set some parameters, others will change with them, like 4 parameters down.
What really scares me is that the program page is blank. No header line. When you try keying in a program, it stays mostly blank.
Battery voltage is good. Power supply voltages are good. I even checked on O'scope to see if there were fluctuations on startup, all voltages started up nicely.
Is it possible the ROM is bad? Or am I not reinitializing the memory correctly?
There was an LX64 board on ebay for $100, so I bought it. It will be a few days before I get it in hand.
Thanks,
Tony
