Need help with my Yamaha RX-V3900! :(

[barrygmu1]

Hello,
Ive never posted to a forum so please forgive me. I am about to give up trying to solve this problem.

I have a RX-V3900, its been great to me, a little tricky to get used to, but great so far.

So this last week, a nasty issue came up. When I turn go to watch cable TV, the receiver doesnt like the cable box (I live in the DC area....Cox Cable, Scientific Atlanta 4240 HDC).

When I turn on the cable, the picture just goes apeshit crazy, flashes, blinks, no sound, nothing.

Settings:
CAble box has outgoing HDMI cable into receiver, then receiver has HDMI cable into TV.

Tests (all were separate and not related)
- Ran cable box (using HDMI) into TV, everything was at 100%.
- Ran HDMI line from cable into diff input on receiver, same problems.
- Switched HDMI cable, same problems.
- I have a PS3, on HDMI, on a different input on receiver, works beautiful.
- Had cable guy come out, i had fantastic signal strength.
- TV works great, i use 1 hdmi cable output from the receiver to the TV. Everything is run on that cable.

This problem just started a few days agotoo. Ive been using the receiver the last few months and it worked great. It just started doing this a few weeks ago.

Ive concluded that it has to be something on the receiver but NO clue what it is. I havent changed any settings around.

If anyone could give me advice/help, it would be GREATLY appreciated. I am about to take it back to the store and get a different receiver. This is my last chance.

Could be a bad cable. Could be a problem with the Cable-Box itself or (less likely) the AVR. Could also be a simple incompatability.

My suggestion? Switch to Component Video and don't worry about it. Unless you are getting DTS-Master, 7.x+, or 3D off your cable box; it component and a digital cable will give you the same results with less compatability hassles.

Hey JerryLove,
Thanks for your response. To answer your suggestions:

"Could be a bad cable." - already swapped them out. Nothing

"Could be a problem with the Cable-Box itself or (less likely) the AVR."
Cable box works fine. I ran it directly into the TV (video/audio) and it worked GREAT!

"Could also be a simple incompatability."
Everything was working fantastically last week. Something changed and stopped working. It is def. a problem w/ the receiver.

My box doesnt have 3D in it.

Just because the cable box works fine direct dosent mean its not the problem, which it likely is (HDCP issue with multiple keys)

As for a quick solution , as Jerry mentioned run component out of the cable box for the video and coax or optical for the sound You will not loose any quality.

Do you think if i swapped cable boxes, that that that might help?

When i bypassed the receiver and plugged the cable box straight into the TV, it worked perfectly (HDMI).

Would it help if i reset my receiver?

What would be causing HDCP errors? The cable box or the receiver?

The cable box is the culprit almost 99% of the time. That model isnt a "newer model" and may need firmware updates. Is there a reason not to run component out of the cable box? or request a different box

Here is another instance of errors that are not HDCP related
