Anyone familiar with the I2C service mode testing on this set? This set has a couple component video/audio inputs working, no svideo working, cardreader, VGAin, and DVI working. I replaced IC3501 which is a AV switch but things stay the same. I find this I2C service mode that supposedly changes bits in chip register using the remote but I don't see them change. I must be misunderstanding how this is supposed to work.... If I2C were dead I shouldn't be able to change any inputs but I can.
