Sorry for asking what I know in advance is going to be a stupid
question, but I tried googling and could find no information.
Normally I work on pinball machines and arcade machines, and I've
never run into this part until I was asked to work on a television set
with bad sync.

Anyways... on the sync board is what I assume to be a rectifier...
marked B12 in large letters, with the number 69 in small letters. I
can find no information online.... any ideas on what exactly this part
is, and its specs?

Why do you think it's a rectifier ?

What size is it ? How many pins ? Construction ? Colour ? etc...


Because it has the cathode band on it, isn't glass, and has two pins.
It's black, and the band (and writing) is brown.

Size ?

Sorry for not providing enough information.

BZY69 was a low power 12V zener.....allegdly 2% tolerance...
