Reply�to: [EMAIL PROTECTED] (ELECTRONICS PROFESSIONALS LIST) ================================= Hi members, I repaired my focus problems by replacing the Focus block. I still have bad convergence, and the pix is bowed equally on top, bottom, and both sides. Does anybody have a fix listed for this problem ? I don't want to buy convergence amps, cause I'm pretty sure it won't fix the problem. I'll buy some if you guys think I need them. Can't afford to waste money buying parts that won't help. So far,..so good,...but,..I need a quick fix,...bad ! Any help is appreciated, LLW LeRoy Westlund Westlund TV & Electronics 97 North Main � � � � � � � � � � � � � � � "Where there's a will,...
