We have a Sylvania projection set that has sound and OSD but no video from tuner or Aux. inputs. We do have video thru S-video though. We don't have a diagram on this chassis. I went looking for the comb filter and realized might need the diagram. Thought I'd see if anyone has had any similar problems and offer some advice? The model # is RSJ445 and according to the tag in the small signal panel, its' chassis # is PTV 310\325 GraysTV/Glenn Gray Berlin Ht's.OH 44814 Phone (419) 588-2325 graystv@xxxxxxx ----------------------------------------------------------------------------- This Email List is Public.
