What do you think the cost of those would be all up?
More myschivious would be to have a library of off codes and other assorted ones like teletext and change input and have it chuck them out randomly. perhaps a burst of volume up or down occasionally as well for good measure
I dont know about there, but here if it did samsung, sony and panasonic you would hit 90% of displays. philips stopped selling here a year or two back and because they were all banned they have blown up and stopped working now, and the rest are the odd bit of off brand junk that you would have minimal chance of getting.
