Well i got my NR808 back from the onkyo california authorized repair place.
I plugged it in, and I used to remote to turn it on and it worked. Then I shut it off with the remote, it worked.
Tried turning it on with the remote, it did not work. Tried the same thing the next day, same thing - did not work.
I didn't feel like sending it back for more work. So I decided to try the fix from moparhowto.com/ht-howtos/fix-onkyo-nr708/fixonkyo-nr708.html
The instructions don't completely match since I have a NR-808. But close enough. I have deoxit, and electronics grade alcohol, and bought the Precision cleaner. So i decided to tackle this myself.
I have some pics, but I am not allowed to post URLs, unitl I have 3 posts. AVS rules.
Here are some pictures of the display board when I opened it up. I guessing the blue marker is from the repair place.
Here is a close up, looks like they tried to clean the board. Doesn't look o good. You can see the residue and scratches.
I sprayed the back of the display board with the Precision Cleaner. After drying there was a haze and some white powdery residue. I used my electronics grade alcohol and a soft bristle brush toothbrush to remove the residue to make the PCB look brand new.
I forgot to take pictures of the after cleaning. I was happy that the cleaning worked, and put the whole thing back together. So far after about a week, its still working! Man this receiver sounds good! Its good to have full functionality of this awesome receiver.
