Attention enthusiasts!  Do you have a CRT projector or home theater procedure that you think others would find useful? Contact the webmaster and we'll post it here!

The procedures in this section are optional and may come in handy for some CRT projector owners.  Most are not everyday procedures that need to be performed on all projectors.  In fact, most home theater enthusiasts will use and enjoy their projectors for years without ever opening the hood or even realizing that such procedures exist.

Please be aware that many of the modifications have been developed by end users that may lack the R&D to ensure that these mods will not shorten the lifespan of the projector or the components therein. Proceed at your own risk with any repairs or modifications to your CRT projector.

Curt Palme, Sound Solutions Inc. and the webmaster take absolutely no responsibility for any damages that may occur due to a 'do it yourself' approach to maintaining, installing and tweaking your CRT projector.  Any modifications or changes you do to your CRT projector is done at your own risk.  When in doubt, ask!
