I have been looking in the the service manuals for both NR509 and NR609, unfortunately they don't use the same HDMI boards anyways.
Links to the service manuals (found by a quick google search):
Which caps did you change? C314, C318, C319, C356, C753, C3101, C3102, C8936, C8950, C8956, C8976, or so? Were any of them bulging, cracked or anything similar?
As far as I can work out, there are only 6 capacitors on my NR609 that seems like the obvious choice. C3104, C8901, C8912, C8915, C8918, C8921. All of them 100uF 16V (as far as I can read the manual and the numbers on the caps, not 100% sure about this)Anybody
with some knowledge. Feel free to pitch in.
