This is not a silly request. I own a Panasonic TC-78SS95A stereo Colour Receiver which uses the M19 chassis. This is a standard 4*3 set. I am feeding it from a Digital STB and wish to treat the TV as a 16*9 set. I need to be able to reduce the receiver height control to get the correct ratio. I have used the STB in letterbox mode but I get black bars of scanned lines above & below the picture. Consequently I am only using about 400 or so of the available scan lines for the picture. If I reduce the height and change the STB to 16*9 I can then utilise all 625 lines for the picture for the same image size. In letterbox mode I get annoying strobing effects which I do not get on Fullscreen mode. Could sombody please provide me with the setup code on the M19 chassis to access the height control. I would be very appreciative.
