Hi, I tried to turn my GEM PRP7 back on after more than two and a half years of inactivity.
After some research, I came across an Italian forum where other PRPs owners were complaining about the same problem.
Some of them have solved by replacing the backup battery.
So I took my PRP7 apart to peek inside.
I immediately noticed crystallized acid on the negative pole of the battery, so I decided to replace it.
Handling the PCB, I also noticed that the same type of corrosion is present on the voltage variator and, even worse, on the back of the PCB some tracks would seem burned near the affected areas (battery and variator).
(I attach some photos).
Do you think that replacing the backup battery is sufficient? Or based on your experience can you already tell me if I have to conder the replacement of other components?
Waiting for your reply, I greet you and thank you with esteem.
