Help me please to fix my monitor Proview 15". The red color is not displayed. With some easy mecanical shocks it was working in the past. Where can be the problem? Please, if you can, send me a schematic for model PV 564 DM. Thanks for any type of help.

The few 15" Proviews I've seen all had bad solder on the CRT PCB - almost complete solder up required
