i know this is a very bad tv but this is what i have :(

POLAROID FLM 373-B hdtv

I need to clear the BLOCK CHANNEL FUNCTION (for blocking hdtv channels) password, i think my kids put it in, default factory password (0000) is not working, also the master reset password (8202) only works for v-chip password, but not for hdtv "block channel" function (this one is in hdtv menu) , already downloaded service manual and it says nothing there other than 0000 is the factory password

is there any way to clear it? i have 3 locked channels out of only 6 that i can receive so you see im in need lol.

would a technician be able to remove that code by removing some component or something? support from polaroid is NULL!
is a 4 digit password and i am sure i wouldnt like trying fro 0000 to 9999.

thank you all
