Question about Onkyo TX-NR801 Receiver
I have my HDMI DVD hooked up to the receiver and it has been working for several months. Now, the receiver does not recognize the DVD by reporting NO SIGNAL. I check the digital inputs assignment and checked for loose cords. Any ideas. I even checked my DVD to make sure it is set up for HDMI. I worry my cats may have touched something on the front of the receiver. Also the receiver recognizes the satellite, tv, etc. Please help.
Loose or crack or cold solder joint holding the socket of HDMI.Cold solder issues - each component is soldered into small
holes on the printed circuit board which in turn connects said component to the
other components. Due to time, heat, use, some solder joints would be cracked
or loose. It is possible that the cold solder is still minimally connected
(hanging by a thread). When the TV turns on heat would be generated which would
be sufficient to further loosen up the solder joint to the point it no longer
provides electrical contact. Jarring the unit creates movement inside enough to
re establish the contact, sometime good enough sometimes not enough.
Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".
Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If this solution help you understand the problem :rate as fixya..
