Brought my LG DVD 2250 to LG service center for firmware upgrade.I wanted to activate the unit's all region function.I was not able to hack since I read in the forum that this model needs firmware upgrade to be able to play multi-region disc and vcd.

The upgrade was successfull since we were able to play DVD region #2,and #3 however there was no video output on the tv..only audio

Is there a way I can use again my LG dvd player?
