OK, I suspect there is a damaged solder pad (poss batt damage after resocketing) for my U16 which controls direct switches.
The schematics are available from IPDB which is good, I've had a read and this is where I fall down. Is someone able to assist me in working out where the pins from U16 should come / go so I can jumper them to see if this fixes the problem? I'm still learning reading schematics and this is above me (again what I don't know could fill a warehouse!)...
The schematics were available from IPDB and I downloaded a copy, but I'm fearful to upload in case of copywrite issues etc...
Any help would be greatly appreciated!
