How Do I fix the convergence on my 2001 Hitachi Projection Tv
I've been reading around and have found that the STK392-110's needed to be replaced to fix my problem so I got the parts and replaced them myself it really was quite simple to do. after i tried out the tv and noticed a huge difference the picture improved greatly but there is still something wrong I double checked my work and it seems right. the red and blue are perfect but the green is slightly out of whack.. how to i get the green to converge with the other colors? at this point I'm kinda at a loss please help.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
Problem #2 CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos aroundimages.
