I have a 32" Toshiba 32A42 set and the overscan is pretty bad. I want to calibrate the overscan using Avia. I also want to find out if my set can do the "squeeze trick," which I've heard many sets can do via the service menu. How hard is this? I've heard I'll need to write all the settings down or else I could seriously screw up the picture. I've also heard I should be able to find the code to enter the s.m. online. Should I attempt to do this? Would anyone like to help (or discourage me from trying )? Much thanks.
