I have hitachi model 50dx10b projection tv that I cant get the digital array screen to line up all the x's so the color will be white. The screen bows in at top and bottom. It is almost like 3 d on some pics. I am new to this site and cant seem to find any service manuals . Can someone tell me where to find free service guides? I have looked on dozens of sites and keep going round in circles clicking more sites. Help!!!
