Hello
Here, I am an electronics technician and I recovered a console avolites pearl rollacue (PRL 157).
I know this console is a little old but I would love to do more about my father who was working on it in the 1990s and I would like to fix it for his next birthday.
So I started by opening the beast before turning on the power.
I found several problems:
1: the 3.6v battery was HS and let some acid flow on the circuit board
so I redid the tracks and changed the battery
2: I then restarted the console this time with the current and the display on the motherboard BORIS 1 displayed a 1221 error.
I searched the internet and found that this error was due to RAM.
I took the chips and checked with the chips tester, they are ok
I checked the circuit board and found a cutting track
I repaired the circuit board, the motherboard now displays several things at startup and goes to OK
3: I had another fault on the screen: the fuse was cut and the backlight of the screen does not work anymore. So I changed the fuse and everything is fine now.
4: here I am now, I block on this problem
when I put the console in system mode and I click on the service switch A nothing is displayed
to have the menu Service, I have to press very quickly between the launch mode of the view and the service I think it's not normal ???
5: I updated the console in 2004 and the problem is the same ...
6: ditto when i'm in program mode and i want to patch the menu does not work .......
7: When the floppy drive is running multiple leds are blocked is this normal ??
thanks for your help sorry for my english
I made you a video to make you see the problem of wet transfer, here is the link:

maybe I should reprogram the LAGs
to know also that my console does not have a video camera the slot is empty of origin
