I have the same tv as lostbhouy24 and have just had an hd tvdrive box installed. I am having the same problems as him and have tried the same things to remedy them as him, hdmi to dvi plus the rgb leads,etc
When i go to the change display & audio setting and make the changes as per the tvdrive booklet and then do the confirm test my picture vanishes. I also do not get asked to confirm that the picture is ok as per the booklet.
When i go back to the display settings it defaults back to my original settings.
Any help would be greatly appreciated.
Please do not be too technical.
