Has anyone had experience with, or can anyone help with this model?
I checked components on the pwr board, that may be common to go out. This pwr
board has 2 regulators the same on it ic701 - STR-F6629B, Not sure of the other
location?
Hor. output xstr Q673 "checks ok" 2SC5612.
I checked a tip indicated R781 "checks good" 1ohm / 15w.
I think this flashing code indicates B+ over-voltage, or under-voltage, not
sure?
The tips I have indicated possible regulator failure, I 'm not sure if bad or
not - does not check shorted? (will order one tomorrow).
I would appreciate greatly if someone could help me on this set? Thanks.
David.
