I got a CyberHome CH-DVD 300S Progressive-Scan DVD Player and I tried to set region code to PAL and then my TV screen starts to flickering nonstop and I can never switch back to NTSC. Then I tried to go into set up again under the flickering screen and randomly tried to switch back to NTSC and suddenly my TV screen went black. I tried to unplug and replug the cables but everytime I turn my DVD power on my TV screen stays black. Can anyone help me on how to get the normal screen back? Thanks

I'm not familiar with this player, but PAL isn't a region code. 1-6 are region codes. PAL is a video standard, and it's not the one used in the U.S. and Canada. You probably need to leave the player set to output an NTSC signal.
