Locked SY-41CL back to life
Two month ago or so I tried to plug a non-existent ROM Image. This resulted in a display showing all @s, otherwise the machine was totally locked. Removed batteries for approx. 2 month - the machine appeared to be still locked.
Finally, I disassembled the machine to check contacts (I'm using a replacement flex PCB by Diego) and to get rid of the charge that was suspecious for the Trouble. Re-assembled the machine, switched it on and ... the trusty @s back in the display, the machine otherwise locked :-( As I noticed that one of the screws did not catch, I fixed that and played with the pressure to the contacts applied by the screws. What I found is, that there is a small pressure range for which the machine is perfectly working! :-) So, if you encounter a problem like this with your 41CL, chances are that you can fix it by gently loosing or tightening the screws. All the Best, Juergen |
