Love you people here. So much real knowledge. Hoping for some help maybe
Acquired a 3900Z receiver the other day. It was free so I decided to check it out some.
Had a blown channel and tuner display didn't light up.
So I Decided to through some OP's in it, along with some resistors.
Channel was still noisy and ended up being some pre-drive xstrs.
So on to the tuner display issue. I was sure it was just going to be bad solder on the flourescent readout. WRONG. I actually have no clue what is going on here. If I play with the power switch I get a moment of readout. Tried cleaning the power switch to no avail. I get 30v to the tuner board (3326) and 8v AC going to "FL" board (3321).
After watching youtube video's I realize I am also missing the preset led and there is a red indicator that shows where on the "dial" the station is also missing. As is Signal strength etc.
Any help would be greatly appreciated. Didn't really want to spend this kind of time on this one but I have come this far......
