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.
