every few days my mitsubishi 65907 user settings revert to torch mode...set is a year old....was isf'd at about 3 months old...contacted the tech...he never heard of such a thing & sugested service under the warranty..........searched this prob here & at home theater spot......was told if i had kids(i do)maybe the 2yr old was hitting the a/v reset button on the front panel(he loves buttons).......so the pc richards guy arrives.....i explained the problem....he radioed to another tech...(in another language)...after some time he said he could fix it in the service menu...initionalize page i think he said....anyway....took him quite a while to get into service mode....his fix did nothing ....so i told him just to disconnect the a/v reset button...he was reluctant at first...but since he couldnt fix it the "right way"..he took out his soldering iron & did the deed...........i was more comfortable with him soldering than in the service menu lesser of two evils...anyway.....no change.......back to torch mode 2 hrs after he left.....what should i do?....im going to call them back...but i have no confidence in them........x box looks great on the big screen but im headed for trouble with this problem...........feel like i wasted $350 on 3 yr warranty...any thoughts?....thanx..
