another thing I recognized is that the TV model can be changed again at the Extended Service Menue mode ...
I had downgraded my FW to be able to change the Model to C6800 ... but with the extended SM I was able to change the model back to 6700 and after that I enabled the pvr option from the extended sub option category
Regards
PS: As I wrote before ... anyone arround here has a clue if it is possible to enable the game menue ?!
PPS: If 3D is working in fact of the picture but the transmitter for the glasses is missing, wouldn?t it be possible to get an external transmitter device for the glasses working ... probably at the USB or serial port ??
