You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

I have a Zenith Projection 50" TV IQC50H94W that has a blue arc


You need to replace your STK392-150 I.C.'s, Also, check all of the large nearby resistors, make sure none are burned, and remember, you have to check the resistance out of circuit with a meter.

once the resistors are checked, and the convergence I.C.'s replaced, you should be able to converge the picture through the user menu.

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.

Blue arc


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.
