The most common thing onthese Hitachi's is dusty or dirty CRT's sockets. All it takes is just for one to be dirty and it will effect the other 2 CRT's. The simple easy fix is to remove the speaker grille, then remove the access panel wich will expose the CRT boards. The CRT boards have to have a screw loose to get them to come off. Be careful as they are fragile boards and also make sure the screwdriver is not magetic and that the set is off. Just take a can of compressed air and blow out the sockets and the pins on the CRT's (again be careful as the pins are VERY fragile and will bend easy). Once this is done put the sockets back in place and you should have a normal bright picture again. If not you do have other issues but, I have fixed I would say 96% Hitachis with dark pictures this way.
