HELP!!!! Zenith XBV243 trouble

[butchbanger]

I have a Zenith XBV243 - I heard about this site and was so excited when I saw the hacks, I immediately ordered several DVDs from the UK. Upon arrival, I punched in the two hacks listed and not only did they not work (DVD said "check disc"), now my screen is completely black and I can't even play regular US DVDs. I have no idea no to delete the hacks that were posted, fix the problem or get the very expensive DVDs I purchased which I assume are PAL to work. Someone please help

oh. i did that to an Apex one time. its messed up forever i think. the second one i did it to however was successful, and now I've got no region, and no macrovision. I recommend an Apex AD-500A.

I did the same thing butch with a little differnt results. I now have a blue screen that jitters. Im sure I messed up the hack some how. So if any one is out there that can help us get back to square 1, maybe a firmware reset hack???? please help us.
