Question about Hitachi 46F500 46" Rear Projection HDTV-Ready Television
Blue and yellow out of focus in semi circle at top and bottom of picture
You Tv has a bad chip ( I recommend you replace both on the convergence board ). 80% or more of the projection sets I get into my shop have this same problem and by replacing the convergance chips, it normally corrects the problem. If you are going to preform the repair yourself, be sure to use lots of heat sink grease to prevent the problem from happening again and I always suggest you use the original chips ( same numbers ) as the after market parts don't always work well. As a pre caution, always remember to unplug the set before doing any work inside the set. Good Luck
