Arcs at the Top and Bottom of the screen!


You will find small 1/2 or 1watt resistors close to the ic's, you must measure them and they must be exact ohms. I believe you'll find a couple open or have changed in value, I hope the new Ic's haven't been fatigued. That should fix your problem.

43fdx01b arc at top of screen


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.
