Hi I have the european version of denon 1920, after the regionfree firmware upgrade it worked fine and i used hdmi output. After 1 week i couldn´t get any hdmi signal from it. The plasma works fine (LG42PY10X)with dvi from my computer but not from my denon 1920. Denon won´t replace it since i upgraded my firmware, i want to replace the firmware to the old one so i can send it back to denon again. Does anybody know where i can find the old firmware?
