Would someone know how to resolve this problem?
I did a test but I noticed that when I save (SAVE) I've always 0> 127, 0> 1452 0 >728 always 0 to the second line of the LCD.
If I try to review the data going back or forward (Row op Column) always displays 0. C1c2p1p2 The external connections are good.

The problem probably is the memory chip.
If I change the memory chip I get the following results:
when press SAVE button always 0>256,
If I invert memory chip (in socket) I have 256>256
If I remove memory chip the instrument don't power on.
Do you know where I cheque the problem?
Someone would know how to fix it?I also note that disassembling and reassembling the instrument often appears always "max" (after power on-off)
in the first line. It seems like there's an electrical contact but I can not find anything.
Tank's very much
