There are 2 large convergence IC's and the one that handles Blue Vertical (BV) has burned out and needs to be replaced. This is by far the most common failure in those projection sets. It is a good idea to go ahead and replace both STK392-110 IC's with the newer improved STK392-150's. If you have never replaced convergence IC's and realigned convergence circuits then have a qualified tech handle it for you.

Usually this means convergence ic's have to be replaced and possibly a few resistors on small convergence board. Sometimes it requires digital alignment after new parts are soldered in. This repair can cost 175.00-375.00.
