scientific atlanta explorer 4250HD problem with yamaha rx-v663

[slickqbn]

Hey guys,

This is the problem i'm getting. I just recently purchased a Yamaha RX-V663 receiver and am having problems when flipping though channels with my cable box (Scientific Atlanta Explorer 4250HD) hooked up to it through HDMI....

This is what happens....

I thought it was the receiver so I returned it thinking it was messed up and got a new receiver (same model).

Once I hooked it up again I got the same issues. So I thought it was my cable box. I just got a NEW cable box today, and the same crap is happening.

Does anyone know why this is happening? Any explanation or any tips on how to fix this issue would be greatly appreciated.

I read somewhere that some cable boxes have issues transmitting a steady signal when going in through a receiver and that I might need to upgrade the firmware. I couldn't find a new firmware anywhere. SO again, any help would be appreciated.!....

Thanks in advance

Welcome to the wonderful world of HDMI... That looks like an HDMI sync problem to me. Since you have to use that cable box, your only immediate solutions are:

Try a different TV
Try a different receiver
Just use component video

I would use option 3.. Should look the same, and you can still have the 663 convert it to HDMI out to the TV.

Of course you could call a lot of people and have them blame the other devices involved.

I agree with option 3. There is something rather odd about most of the SA cableb boxes. I have nothign but problems when I ran HDMI. Now I am running component and I only have problems some of the time. :roll:

Yeah I ended up just hooking the components back up. And you're right...i completely forgot that the 663 can covert the component signal to HDMI...thanks for the advice Kev!

What kind of problems are you experiencing with the SA box connected with the components?

None really cause by using components.

I should have said it differently. The problem I have now is that my box pixelates periodically for no reason.

My SA8300HD doesn't have any issues at all when changing channels. I get a 2 second "flicker" then the picture comes up, but I'm guessing that's all due to resolution changes and handshaking.
