Pls elaborate on hint of pix. Also did it have normal sound like from
a source ?
A normal good running TV should have nice strong clean snow & a
nice waterfall with no signal. Weak snow or a blank screen points
to the IF most the time. Depending on the design the 33 V may
go right to the tuner or be divided down before. Also band switching
can be external or internal to the tuner. Newer sets will do everything
inside the TNR & have data, 5V, & clock pins........
