[QUOTE="Terryl, post: 1089151, member: 369937"] Well the thing is, if that battery is dead it maybe a voltage problem in the memory circuit, removal or replacement would be a tell. It does have a blocking diode after the battery to prevent this from being a problem, but what I don't see in that circuit is a way to recharge the battery. Here is a blow up of the memory circuit, Q02 and Q03 are the memory IC's, they get their VCC from the two diodes D12 or D13 depending on the power conditions, there maybe a problem in that circuit. [ATTACH type="full"]130540[/ATTACH] This control PCB handles the display. [/QUOTE]
