When I made the scan of the Philips VG-8230 and VG-8235 service manuals, I only had a photocopied low quality version of the manual.
The quality of PCB and circuit diagrams were not optimal.

Thanks to Jipe (Jean-Pierre Dubois) I now have improved circuit diagrams(VG-8230 and VG8235) and PCB (VG-8230).
