Hitachi projection mod# 46f500 the tv picture has a wave across the top about half way...tried to magic focus in the menu screen but no luck any suggestions....thanks
You most likely have a convergence chip bad. In our shop, when we are working on projection TVs, we find that about 80% of the repairs we make are the same problem you are having. You need to replace the convergence chip ( there are 2 of the same chips on the convergence board, and I suggest you replace both ). If you are going to attempt the repair yourself you'll need to remember to use lots of heat sink grease so you don't have the same problem again. Also, try to get original parts, as there are times that the after-market ones don't work well. As a precaution, always remember to unplug the set from the wall before you do any work on the set. Good Luck
