Question about RCA HD52W56 52" Rear Projection HDTV
Question #1 can you look on back and see what the chasis # is and also there is in small print a # that reads model like hd52w56....yx1 or yx5 or something like that. i need these numbers because there are certain models that have service bulliteens. also when ordering parts u need to get right parts. The sqealing from a coil usally indicates something is loading.that cuircit. you may have a component shorted. ussally when a tech hears squealing he looks at the horizontal output and flyback as the primary reason for this. Recently the prices for some of these boards have come down. and may be the best route to go.
