I have a Toshiba 53HX71. I noticed tonight with Avia (widescreen test pattern) that the right portion of the screen is slightly larger that the left. What value in service mode is used to adjust this. I've been to the Keohi site and couldn't find an answer. I did find various vertical bending adjustments but no horizontal. I thought this adjustment may be in the design mode, but I can't access design mode with the directions they provide. Anybody got an answer? I want to decrease the height of the right half of the screen.
