A couple of months ago my R10 (which I prefer over the newer DirecTV DVR) starting pixelating heavily and even spontaneously rebooting or freezing up; the picture would freeze and the sound continued on. So I checked the transponder readings and they were quite low (average 55). So I cut down a whole bunch of tree limbs and got the transponders up to 85-100 except for two that were zero. The pixelating/freezing problem continued so after reading googling a bit I -1- replaced the R10 with a refurbished one from WeakKneees (no improvement) -2- Replaced the LNB (no improvement) -3- cleaned the coax cable ends (the transponders readings went down to 80-95) -4- checked the dish positioning (could not get it any better) -5- bought and used a coax cable continuity tester (all read fine) -6- went online at DirecTV and "reauthorized" the dvr and then just unplugged the dvr for about 3-4 hours ( this probably made the only real discernable difference in that I watched tv for about an hour and a quarter before it pixellated, the longest amount of time for quite a while). Unfortunately today when I got home and turned on my tv, the picture was once again frozen even though the sound was continuing right on.

Sounds like your second receiver might be bad too especially since the sound was OK.

If your signal was bad, the readings would probably go up and down on the transponders instead of being a steady number.

When you checked the dish positioning, was someone watching the transponder numbers when you moved the dish?

No, I just had the volume up and listened to the tone until it was the highest pitch.

Using the volume to listen to the pitch is a good way to peak the dish, you're probably good there. That second receiver is probably bad.

What type of input to the TV are you using?

Is it HD or analog that's freezing the picture?

Hmmm... I just got it refurbished from WeakKnees who usually checks those things over pretty good, I do have a post at their website asking for advice also.
I only have SD. My connection goes through a DVD Player/Recorder and then to my tv using an RCA connecting cable (I think that's what you call it.) My sound goes to some external speakers also using a RCA connecting cable.

Have you ever bypassed the DVD Player/Recorder when it's happening?

That's an idea. I'll try to set it up that way to see.

I got to thinking about it and realized that bypassing the DVD player doesn't seem like it will make any difference since programs recorded on the R10 also are pixelated and the signal didn't go through the DVD player. The player is between the TV and the R10. It goes like this  [ dish->receiver->player->tv ].
I did get a suggestion elsewhere that I should hook up the receiver in question to another satellite dish that I have set up across my property. This would tell me whether it is the receiver that's defective or if it's something else. I'll try that this weekend.

It's probably not the player, but since the video always passes thru the player before it hits the TV, it's probably worth checking before you make a final decision.

When a dish is causing pixelation, the audio is usually affected too, but there always an exception to the rule.

After swapping the two receivers attachewd to different dishes, I found that the pixilation went with the receiver and did not stay with the dish. It has to be the recently purchased refurbished receiver which I will now request a replacement.

As I said, it took swapping the receiver with one on a different dish to tell whether it was the receiver or the dish.

Glad you figured it out, hopefully three's a charm and the next one will work fine.
