Shopping a PCB
From: “Frank-Rainer Grahl”
taking out cpu
replacing battery holder
replacing 0 Ohm resistors for language settings with Dip Switch
New rom version.
Replace burned GI haeaders
Replace 5W 4K7 resistor at the bottom of the board and mount it farther away from
the PCB. If it looks burned I replace the whole section.
The resistor is monted too near the pcb and is in my opionion responsible for 50%
of all driver failures. Get’s too hot, burns the boards and other parts around
suffer because of this.
