Chassis PTV705-AH01: Green and red conv is OK, i do not have schematic, this set does not have large STK ic's, it has tab mount type transistor outputs. I compared voltages on all transistors and small ic's of blue amp to green amp and found no significant differences. This set does not have the large conv adj board that we are used to seeing therefore it must be all acheived thru the micro. I can access the conv menu and align all of the colors of the center conv fine but the outer parts of the "blue only", are way off and bowed at top and bottom. If anyone could help i would be very appreciative.
