Hey All
I have a Toshiba TP48E50 4:3 RPTV that is a few years old. I have been trying to readjust the 1080i compressed geometry and have run into a snag. The 16:9 raster area was too short so I adjusted it to proper 1.78:1 ratio using the HIT function in the service menu. Previously the geometry was properly adjusted within that raster area so now it's slightly off on the vertical plane following the HIT change.
Here's where my question lies: what parameter do I select to adjust the image overscan, centering, and geometry within the 16:9 raster area? For whatever reason the image is off-center vertically, showing about 4% overscan on the bottom but 8% on the top. When I try VPOS and VCEN parameters the entire raster moves, not the image within the compressed raster. I have also tried VPS but with similar results.
I need to a) center the image vertically, then b) adjust the height within the raster to restore proper geometry. Any assistance would be appreciated.
