Afternoon guys and gals,
when the power at my place dropped to about 50 volts rms
apon turning the STB back on I was asked for my pin. Well I entered
same but the STB kept asking for said pin. (NOT changed from default)
After MANY (>10) calls to the service line the blood thing still was =
locked.
I was amazed that from all of the technical assistants their standard =
answer,
"unlock the STB from the menu". VERY hard to do when all you have is a =
blank
screen that is just asking for a pin at switch on. There was another =
message that also
said ,"No or BAD signal" (that was not the case!).
So I sat down with a cup of coffee and thought what sort of BACK DOOR =
would TEAC had made so that ANY pin could get overridden.
t had to be simple, & it was.
press the four 'top text' buttons in sequence.
RED, YELLOW, GREEN, BLUE when asked for the pin
Then I did a reset, rescan etc. All was normal again.
BTW I changed the pin a few times to test this,
Regards,
Mitch

that also

TEAC had made so that ANY pin could get overridden.

Out of curiosity I dumped the latest firmware images:

Near the beginning of the code is a text string, something like
"Digital Yellow Green Blue Orange". I wonder if that is significant.
