It is a cheap TV that performs well, though woefully shy of an RS232 port. Just wanted to pass along some things I worked out and am trying to work out.
Service menu:
On factory remote, press MUTE, 1, 8, 2, and power in quick succession while the tv is off.This will open up the service menu. Go to options, and then model... change it to the 560. This enables hardware that allows 24p playback. They are the same tv, with different hardware access. I have been looking around trying to figure out if I can turn "overscanning" or some derivative of it off so that KDE will be the right size.
I also know that the 650b service code is INFO, MENU, MUTE, Power.
I also know that you shouldn't go around screwing with things you do not understand in these menus. Use at your own risk, but I can tell you that the upgrade works on the 550.
