issue with loseing signal.

Hello all, I have been having issues for a while now with my system, and can't for the life of me figure out why.

There are 4 parts.
1) HTPC (ati 5670 HIS card)
2) shaw digital cable box
3) yamaha reciever (Rx-2800 I think, about 2-3 years old)
4) hitachi TV (rear projection)

do the 2 source units feed in ot the Yamaha, via HDMI
Yamaha in turn feeds the TV

What happens:

It used to happen once a week, +/- but on Friday it happened about 3 times during one movie. The screen gets corrupted, sometime it goes "pinkish" some times it goes "greenish", some times it goes solid green, and the other day it decided to only show the top 1/2. Sometimes if goes all black too.

This issue seems to happen mostly with the HTPC, but I think it did happen once of twice with the digital PVR as well.

I have swapped out the cable going form receiver to TV, but still having issues.


Possibly related, is that I can't seem to launch catalyst control center when using remote desktop (I have not tried locally). I uninstalled the drivers, and reinstalled, still nothing (on remote desktop).

Try connecting the HTPC directly to your T.V. If it does it, try using a KNOWN GOOD HDMI cable. I would do the same with the PVR if you've seen it do it as well. To me it sounds like an issue with either a cable or the HDMI interface on any one of the components.

If neither do it connected directly to the T.V. it's the receiver. If the do even though you used a known good HDMI cable then it's the interface on either the source component or the T.V. At that point I would try connecting the HTPC & the PVR to a different T.V.
