Dead Calcs

Hi all Quite often I get an old calculator (any make) and the LED display on powering up will display just a row of decimal digits and will not respond to any key press. Does anyone have any ideas on what appears to be quite a common fault amongst all makes and models, and how to repair etc. or at least where to start looking. Cheers to all - Dave May www.collectors-tech.com
