I have an onyko 919. It has a hum problem at cold start which eventually dies / goes quiet. I have been "chasing" it for a while. Tightening ground screws and checking a few places. Basically, the problem is in the "back half" of the unit.... that is, if I take the sound out of the "pre-out" and feed it to a stand alone amp, it is good. If I feed in a signal at the external decoder input and play thru the back end of the onkyo, it has the hum.
Anyway, along the way (the chase), a number of components (resistors, capacitors, etc) on the main board and the DSP board are loose and appear to have "cold solder joints" or equivalent (ie. poor solder connections). These may be contributing the problem... maybe. Some are addressable with the boards in place BUT the DSP board is at the back of the front panel and the board itself needs to be removed. :-(
To get the board out, I have been fighting with "damn onkyo ribbon connectors". The individual wires of the "ribbon" are "ribbed" and each appear to push into the body of the connector. I have ruined on connector that I have included a picture of. It has 5 wires / pins. As you can see the wires are somewhat "ribbed" making it very hard to pull them out of the holder. As you can see, the entire body of the connector pulled away from the board... :-( I think I have figured out how to remove the wires "normally" by pushing down on the "top holder cover" of the connector. My question is: Does anyone know what the name of the connector is referred to as and can they be found anywhere for sale?
To get at the board, I need to release about 5 others and am hoping not to "crunch" any others.
Thanks for any help / direction.
