I've got a WG 25K7401 that I'm working on. Before powering it up, I found an open resistor at R120 so I replaced that. HOT and fuse were good and everything else looked ok. Fired it up and all I'm getting is a white screen, with or without a video signal connected to it. The B+ as measured at TP202 is 118v. Haven't installed a cap kit yet (the caps seem to be original) but one is on the way.
How reliable is the U500 RGB amp chip on the neckboard? Any chance that is bad? What else should I be looking at?
