I replaced D735..no change. I do have 6.2v on cathode.
I would like to know what the voltage is to be off pin 1 of the STRF6515..I can
not find any pin-outs on Google, BD Enterprise. I'm getting ~1.5vdc on pin 1.
There is no B+ to FBT and I still get the pulse sound from the speakers.
5vdc REG is normal.

Unit came in with what sounded like a heart beat through speakers..no power up.
Not regulating, I have no print.
I have voltage that jumps from 17.5vdc to 18vdc and back on pin 4 of STRF6515
and
163vdc on C705, sounds high.
Supply voltage to my 9v reg is jumping around like crazy.
Checked my caps in these areas and resistors and all check OK.
Power button has no effect and nothing on HOT, but I do get a chirp when I plug
unit in.
Has anyone seen this?
Thank you.
