PostOther hack posted by Nobody Special, April 14 2003:

This is the hack to view the firmware version... it also shows the prom values which appear to be a set of registers composed of 2 hex numbers per register for any hackers that wish to experiment.

with the power on
press "SETUP"
then choose TV ASPECT from the menu
then move over to the option 16:9 wide
press the numbers "1397139"
press "ENTER" it should show the version and some other data
press "setup" when u wish to exit

it is a good idea to do this before u experiment with hacks so that u can write down the original values incase u need to restore them

my values were as shown here:

Model :DVD5201
Region No :1
Chip_ID :Pantera II LE
Servo_Ver :V2.04 MP.
Prom_Option :55 53 00 4C 12 55 01 FF

Factory Reset .. Done

note that my model is the same as the zenithdvd5201
and i assume that the my zenithdvd5551c has the same progaming as that model

also note how my prom values change as i add hacks

6. press "PROGRAM", "6", "PROGRAM" "5"
7. press "ENTER"
