    From day one I have been having pixelation problems on my new 722. Dish has come out and rewired the house & moved the dish. Today I discovered a History channel recording from last night was totally unwatchable. I switched back to live TV and had very pixelation on the History channel. I went in to the menu to check signal strength and noticed the receiver was set for input to tuner 2, I switched that to tuner 1 and the pixelation is completely gone. I cannot find anything in the manual about the different tuners. Should I have the receiver set to one or two? If two is having pixelation problems should the receiver be replaced?

    Well - both tuners need to be hooked up, but if you're getting that much pixelation and it is hooked up right - I'd say you need a service call.

    Pixelation can be caused by either your reciver or a failing LNB (or possibly bad aiming).

    I didn't unhook anything. I changed tuners on the "point dish screen". BUT now I find that a show I recorded this afternoon is completely pixelated also. This was with the new setting.

    Hi Steve, I am sorry that this pixelation issue is still occurring. There is not a way to change the tuners from the point dish screen. Did you happen to run a check switch test when you were in that screen? If not can you please do so and tell me if you get an error message.

    Then lets go to TV1 and place the receiver in Single Mode and then using the "Swap" button on the bottom of the remote, place both tuners on the History Channel and then please tell me if you are only having the distorted picture on one of the inputs.

    Were you home when the tech was there on 11-28? Did he check the full system for the pixelation issue?

    Also on a side note, has Blockbuster gotten your e-mail address changed yet?

    Pixellization on one tuner, but not the other is usually a sign of a low-frequency obstruction (barrel, wall plate, RG59 line, etc.) somewhere in the signal path. The low-freq obstruction causes problems with the signal for the 2nd tuner as it is band-stacked in the higher frequency range and is interrupted by said blockage. Tuner 1 operates fine because it is band-stacked lower and isn't blocked.

    Mary,
    I did your test as you asked above. No error nor error code.
    When I did the swap test on the History channel tuner 2 showed A LOT pf pixelation (see pic below) while tuner 1 was clear.
    I have been here each time the techs have come out, they have moved the dish and run new coax from the dish to the receiver. Their latest claim is my microwave internet signal is interfering with the Sat. 129 signal. The tech claims the dish signal and the microwave signal are crossing paths and causing the problem...............I think tuner 2 is bad. The tech wants to come out next week and move my DISH dish to the other end of the house so that the signals won't "cross". I think he needs to replace the receiver.

    Blockbuster has NOT taken care of the email problem. Ray C @ DISH has logged into my account and seen the problem first hand.

    Here is a pic of the pixelation on tuner 2

    Thank you for doing the troubleshooting steps for me,Steve. According to your account notes, you have had the receiver replaced 3 times and is still having this issue. That pretty much says that the problem is not with the receiver. Passing the Check Switch Test tells us it it not signal related. The technicians do normally carry replacement receivers on the trucks so he decides it is warranted he will replace the receiver.

    I contacted Blockbuster again and the work ticket is still pending for the e-mail change on your account. We will continue to work to get this issue resolved and I will check again when I return on Tuesday.

    The first "replacement" was when my 622 stopped working (totally dead), it was replaced with a 722 which lasted 3 hours then had a hard drive failure.
    The pixelation got real bad with this newest 722. You can't blame the previous two receiver replacements on pixelation problems.

    All the way to the receiver? As in you see them pulling a new cable through the wall right behind the receiver? When I move a dish as a tech I typically only rewire from the Dish to the ground block, not from the ground block to the receiver (unless it needs it). I still say you have a low-frequency item in the signal path somewhere. Could possibly be a defective separator/triplexer too.

    This can happen, but it would affect both tuners, not just one or the other. Seems unlikely to me.

    I don't see where anyone has had you switch the inputs to the receiver. There should be one cable that has a Y on in, with two inputs to the Receiver. That is for the two tuners. Switch those two inputs.

    If the problem remains exactly the same, it is the receiver almost for sure. If the the problem is now on the other tuner, it is something before the receiver.
    When go to do this, are the two inputs connected tightly? If one is not that could just be the problem too....

    They ran new from the dish, under the house, into the house to the back of the wall plate. From the plate to the receiver is older (less than 2 feet of coax but a lot of hardware).

    Spoke to my local DISH tech today. He had me call and have a new receiver and a new separator sent out. I should have those here and installed in a couple of days.

    Did you ever take my advice and try switching inputs? It is just about certain to tell you where to start looking for the problem....

    It doesn't matter how short it is if it's RG59. Also what do you mean by "a lot of hardware"? Do you have to cable going through a surge protector or something? Are all barrels (splices) in line blue in color (including the wall plate)? Pics can help a lot here.

    There are 4 separators/splitters, all installed by DISH. None of the coax is going through a surge protector. Any/all barrels are blue and installed by DISH. The DISH tech tells me none of the coax is RG 59.

    With the new separator and receiver the pixelation is now on both tuners BUT it is not like the long term pixelation I had before. Now it is just a very short burst that last about 1 second.

    Steve - you need to be very specific about what is hooked up to what. A "splitter" that would work fine for OTA / RF distribution will not work on the LNB cable.
