Page 1 of HELP LG 4210, BLANK SCREEN,AFTER ENTERING VCD HACK.

Hi Can anyone help I entererd the vcd hack into my LG 4210, after I switched the machine back on the screen was blank, when I put a DVD in there is no picture but just the sound, what do I have to do to get it back to its original settings, or is it beyond repair.
Will it have to go to a shop to be repaired PLEASE HELP???????????

As far as I`m aware this is the region free hack:

1: Press Pause on your Remote.

2 :Using your remote press 3,1,4,1,5,9 in sequence.

3: Press 0 for Region free, 1 for Region 1 or 2 for Region 2 (on your remote).

4: Press Pause on your Remote.

5: Power off your player and wait a few seconds.

6: Power on your player.

Hope this helps.
