Has any had any problems using generic STK's in this Hitachi made Zenith TV? Hitachi calls it a HIBRID IC and it cost $21.45. You can get the generic for $8.89. This set bows in top, bottom and both sides. Bowing and convergences off on picture and OSD. Checked techassist archives and found nothing on this model that related to convergences or Bowing. I have the schematic for the Zenith. Any one know what is the closet Hitachi chassis is?
