Hi there! Thanks for your reply. The picture of the board was taken before cleaning. It has been in my ultrasonic cleaner. Tracks repaired. Replaced some parts. Gone to bed yesterday evening and woke up with a fresh head.. grabbed my multimeter and found out one logic had bad ground connection...DOH!! fixed that and plugged it in...yay!! Kicked the old and heavy CRT out and installed a fresh TFT screen It is fully working again and will soon belong to Geronimo

Thnx Geronimo, got it partially working now. Screen shows something but not all. Reset button and clear meters button works. Cleaned up the battery moisture and repaired some lines. Replaced some components. All ic's are rebranded with specific codes wich makes repairing the board really hard. Programmer reads most of the logics but not all. I'm really getting stuck without the schematics Anyone familiar with this (really old) system?

Lovely looking machine, never seen one of these before! Still looks like there's quite a bit of battery damage in the top left corner of the board (next to letter G) - you really need to clean that up and you will also find quite a few components in the area where the battery was are shot. Hopefully nothing too major though as it's obviously booting up. Can you take a few close-up pictures around the damaged area to see what's been attacked?

Maybe a good idea to start a new thread on this one and see what the response is?

Thank you for the fantastic layout.
