In my (seemingly eternal) quest to get my Sharp LQ6RA01 working at a satisfactory level, I ran across this .pdf which might be useful for anyone interested in LCD display troubleshooting. It's like the troubleshooting page in the back of a VCR manual, but it deals with solutions for problems like double pixels and jittery images.

It's geared towards Sharp LCD modules, but I imagine that it would apply to most manufacturers' products. It looks like it may solve some of my problems and I hope it provides solutions for someone else's.
