Aeito Posted July 14, 2011 Report Share Posted July 14, 2011 Hey guys, I got a Line Backer really cheap some years ago, but it is not working. I replaced allready all IC, the battery, overtone controlled oscillator, but same error appiers (I didn´t replace the "RAM 32K" and "Eprom" and the IC "74HC02"). The display shows just 2 black bars. The line backers was working a little bit 2 years ago, it was possible to control round about half of the DMX chanels. When I tried to control a chanel over approx 250 the line backer crashed. Anybody know´s what can I do to revive the line backer. Could it be the firmware, so i have to flash an new one on the Eprom, or will it be the CPU, which is dead? The Firmware must be from year 1996, so it will be a really old one!!! Thanks for your help!!! Quote Link to comment Share on other sites More sharing options...
KWR88 Posted July 15, 2011 Report Share Posted July 15, 2011 When you replaced the battery what condition was it in, was there any signs of corrosion etc. It would be easier if you PM on the address below.
