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.


Good Luck!

It sounds like the LCD panel is badly damaged, if that is the case, it will not be worth it, sceen is the most expensive part of the whole TV, you may be able to sell each parts of the TV on EBAY. Post the pictures of the screen will help.

No video, audio ok


If you do not get any pictures with any kind of video sources, then there are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
