Did you try any other passwords? Like "92729272" or "12345678"

hold down the yellow trouble reset button while booting, and see if you can s00s01 and try the 9272 four times and twice from there.
if you get in you can change the password from there, stop9 stop 0 clear. i think

Try what Synthohol suggested. He was right if you can get in service mode using backdoor you can change password. Once in service mode press Stop, 0, Clear to enter Enhanced security mode where you can change CE password & also turn off CE password.
