Hi all,

New to this board, and actually, quite new to repairing a Commodore PET 8032-SK. :)

I need to repair it, because it has an issue:

Actually, it has changed a bit now. Only the first line is beeing repeated now (the line with the basic version).

What I've done so far:
- Reseated all socketed chips
- Checked the board's voltages (they're ok)
- Recapped the board

When I leave it on for some time, there is no obvious overheating of certain chips.
I can hear the regular normal beeps when I turn it on.

This version has the universal dynamic board: 8032089

Does anyone have a clue on what could be causing this issue?
Any help would be appreciated.
