Dear everyone,
Nice to see this forum is still buzzing.
Since obtaining my Lisa, it has been a bit of a journey to get it all working.
Currently there is an issue that is leaving us unsure of what to do when powering on the machine (see photo below)
- all the electolytics have been replaced on the analog board and no success in fixing this issue.
- the TDA 1170 has been replaced which caused a horizontal line
Does anyone have any thoughts or further suggestions?Regards,
Have you checked the supply voltages on the video board, 5V, 12V, 28V.
It might be worth checking the pots on the video board as well.
Regards
Geoff B
