    My old switch was a Zinwell SAM-3402. My new one is a WB68. I don't have any wallplates either, just lines run directly to the devices.

    Might be time to take a trip to Home depot, Walmart or even Eckard's or Publix and spend $5. You will eventually find a use for a coupler or 2.

    OK, if I get some couplers, I have 4 lines coming from my dish. Which ones do I use to connect to my two lines into my HR20?

    Try removing the surge protector from the signal chain entirely. I've had DirecTV for over 10 years and never put mine through anything like that. Besides, you SHOULD have everything grounded through a ground block anyway.

    "any two" from the dish to your HR-20, since you would then only be using the dish multi-switch.

    I missed that. Absolutely disconnect the coax from the surge protector and run it directly.

    OK, I just disconnected the surge protector entirely and ran the cables directly to the BBCs, then to the HR20. I will try this for the rest of today and see how this works out. I have a guy coming from DirecTV tomorrow to see if we can solve the problem but hopefully this will fix it. From what I can tell, the ground wire from the satellite dish is connected directly to the multi-switch. Is this correct?

    OK, ESPNHD is pixelating right now. Is this happening to anyone else?

    To explain it further: remove everything down to the minimum needed to connect the receiver to the dish. Start with a "baseline" and then add the pieces in one at a time to see which component is the cause of your problem. [standard troubleshooting].

    Little League? No pixilation here.

    I change off the channel, then change back, pixelation is gone. Something I noticed when taking the cables off the surge protector. The white plastic insulation doesn't come up flush with the bottom of the connector. There is probably a good quarter inch or so before the white plastic and connector. Could this possibly be causing a problem.

    The main problem with troubleshooting this problem is that it only happens about 10% of the time.

    It sounds like your cables need to be "redone". I had the same problem with my first install: loose cables and every connector had the "air gap" that you describe, which can cause you problems at the higher frequencies [bad RF match].
    Next would be to make sure all of the bolts are tight on the dish too [so it won't move later].
    Signs of a very poor installer.

    In lieu of going to get couplers to bypass the WP68, you could move the cables around into a different order sequence on the out side towards your boxes. This would tell if you have a bad port. But I would recommend you get the couplers to prove the switch is ok. From your past experiences, I would think you would like to be able to just tell the tech what needs to be replaced, instead of watching him scratch his head.

    That is true, have you swapped rooms with this unit? One or 2 bad connections could be the source of all your troubles.

    I plan on doing this tomorrow. Getting him to replace the switch and redo the ends of the cables.

    What is strange to me is that this is ONLY HD channels. None of the SD channels are having this problem.

    Could be just "that cable" giving you the problems. You can try to swap the cables around and see if it will change. [back to basic troubleshooting, minimum components and then if still present start swapping the minimum around].

    If the picture is fine when I first change to the channel, then it pixelates, that would mean that the switch isn't the problem then, wouldn't it?

    Also, doesn't the DirecTV techs have a tester to test signal strength? If so, can't they just test it coming off the dish, then off the multiswitch to see if that is the problem?

    RF isn't that "simple". The installer meters don't look at "a channel", but all of the transponders that are even or odd from a SAT.

    You have to think of it more like a series of tubes.:lol: Seriously though, if a data stream is clogged or bogged down by a bad connector or piece of equipment it can come and go. When the data is light it is fine but when more information need to be pushed faster, it overwhelms the defective location and does not pass it.

    How about trading the HR10-250 and HR20 for an hour at their locations? This could help to step back and see if it is a simple cable trouble or more in depth.
