Help with making a convergence grid overlay/find service manual for rear projection tv?
The tv i have is a hitachi 43' rear projection tv model 43uwx10b, which i got from a friend who gave up on fixing it. He replaced the two convergence ic's and for some reason did a memory reset... Normally the green is always good and you can line up your blue and red off of that, but after the reset the green became off also. I can move all the colors good but i hitachi 37 inch 1080p lcd hdtv have nothing to line the grid up with. I am not sure what they are called, I think maybe convergence grid overlays, basically plexiglass with a grid drawn on used to line up your colors on. i would like to know how one of thes convergence grid overlays could be made. i don't know how to find how big the rectangles are, or if they are even rectangles! Are all convergence grids in squares, or are they just rectangles? Also I think a service manual would help, but after much searching i have only found a link to a site that is no longer in service.... If anyone knows where to get this that'd be great :) --- not sure if this helps the grid part but i did it anyway... the length is 37 and 7/16 inches, and the height of the screen is 21 incheswell its pretty messed up.... heres a pic http://img109.imageshack.us/i/120909212400.jpg/I will be glad to provide any extra info if needed! :) thanks in advance!
