The unit does have an auto power off if you have not used it for 5 minutes or so. Is this what you are experiencing?

What i noticed holding a couple of NEC PC-8201 and PC-8201A in my hands, that many have a strange display issues: Unit working fine, after some time display is getting blank and i can't see anything on the LCD. After switch off/switch on - its fine again. I noticed this problem independent prom Power Source (On AA Batteries and 6V DC Power Supply) On some units this problem is getting better when replacing old NiCd Battery with a new one or with 1F / 5,5V Capacitor. But still not solved completely. This is a question on our gurus: Is there a chip (Or couple of chips and/or other components) on the mainboard which can / need to be replaced? I am not so familiar with old electronics, nor i have an oscilograph. Is it possible for an avarage user with moderate soldering skills and multimeter to solve such issues ? Thanks! -- Kind regards / Mit freundlichen Grüßen ExPLIT IT Solutions Pawel Radomychelski
