Viewsonic normaly does not sell service manuals to non contracted servicers. You can call Viewsonic and see if they will sell you a service manual.
With the Pasma and LCD sets that we work on (we are not a Viewsonic rep), they are all supported from the manufacture for mainly board swap only, just like in a computer.
The circuit boards are mostly using SMD technology mounted and embeded in to multi layered circuit boards. Troubleshooting these boards is like trying to troubshoot computer boards. There is almost no supported component level service. In any case, you would also have problems to buy non generic type replacement components.
The service manuals do not always have detailed schematics of all the boards. The manual is more for modular assembly, specific types of service, and for doing the factory level alignments.
