1st hack: a toshiba 27" tv with a remote control that had this stupid reset button: the menu keys were on the tv, and if you accidentaly hit "reset", it would undo the picture settings and the only way to restore them required getting up and going over to the tv. A major pain. Missing from the remote was the last channel recall. Fixing the first problem was easy, just cut a trace in the remote. Second was more chalenging: when I first had the remote control apart, I noticed several "keys" that operated various functions like menus and the last channel recall. These keys were shorter than the rest and didn't poke through the front panel. I put a coupla jumpers from the hiden last channel recall to the old reset key. one jumper couldn't be soldered because of some kinda carbon deposited to the board that wouldn't accept solder. I put a bit of glue on the jumper to hold it under the key. The reset key became a last channel recall key! Still works. Second hack: Friend got a mitsubishi home theatre unit. It has a single input and dolby pro logic and a 5 channel amp. Only problem: although it has outputs for rear, center and subwoofer, it didn't have any preamp outputs for the front channels. This was going to make it really hard to integrate into his current system. Also the built in front channels were mediocre compared to the amp in his current system. I had a look inside, found where the signals fed the internal front amp, cut the signals going to the center and subwoofer outputs, and jumpered the front signals to go to the center and subwoofer outputs.
