    Hi,

    I have the following "blue-line" like problem with Component video output in 3 out of 4 stretch modes including the zoom mode that I use most. I can't remember off the top of my head which stretch mode doesn't have it.

    It occurs in about 10% of the content and doesn't occur with S-video output. It appears as a series of blue and/or red dots on both recorded and live material. It's always one vertical line exactly in the center (horizontally speaking) of the screen and appears as a series of closely spaced dots.

    Is this the blue-line bug?

    Check out the attached pictures

    Regards,

    Steven

    Steven, your pictures look different from the other ones that have displayed the problem, but if it's happening only with the component video, it's definitely possible. I'd recommend sending your pictures to the email address posted at the top of the forum and asking them the question.

    I sent this information into dish and they offered to repair it.

    I'm going to make sure to have content on the system with the blue line bug and instruct them how to locate and replicate the issue so they can verify that it's there and that it's gone when they make the fix. I'll report back after I get the unit back.

    Steven-
    Looking at your pictures I now realize my old 921 also had this problem, along with the blue-lines...at the time I thought it was a source problem. Dish did fix my blue line issue, but found other problems and sent me a new 921. I received it yesterday and so far all is well.

    My first 921 and first 921 returned for the fix had both blue line problems mentioned in this thread. My recently received second 921 that was purportedly screened for the blue line problem appears to be ok but I have done only limited viewing so far. Dish was very anxious for me to send the first "fixed" 921 back so that they could do further testing to determine why the fix did not work. Hopefully they are figuring out this problem with the component outputs.

    It's very close! I had the blue line problem and got it repaired, and now I have the green/red line problem that you seem to have. I will take pics and add to my post this evening.
    (Update: Pics are uploaded. Red line is harder to see in my picture, but it is definately there. The green line is pretty easy to spot)

    Steven, I have seen something similar but it only happens as a fluke and happens when my box is set to SD and it is trying to pipe out data through the Y/Pr/Pb, even though SD is the only light on. Once I change it to HD only - it corrects this problem. Does this seem like the problem you are having?

    No--I always run mine in HD mode with component cables (good ones)attached.

    Steven Miller,

    I have the exact same line issue, on my 921, that you are having with your 921. I am using the component out to view SD.

    I haven't been able to repeat the problem, even with the original program material that I saved that originally showed it. I tried for over an hour with various recorded SD (and some HD) through the HD outpouts, various stretch modes, etc...

    I wonder if it was a particular mode or setting combination similar to what you mentioned above that I haven't successfully replicated. Or maybe a combination of events put the hardware in a state I can't repeat.

    I'm not going to send my unit in right now because it seems to be working fine after about 10 hours of viewing SD content over a component connection. This "fluke" has only happened on that one day and never since. I don't want to send something in for a fix if I can't even verify the fix (the risk of shipment, etc.. may be higher than the benefit of getting a fix if the unit doesn't need it... plus I don't want to live without my HD DVR!).

    - Steven

    I just noticed this problem on my 921 and the pictues you posted are exactly what I am seeing. I've had my 921 for about a month now, but am just noticing the single blue streak tonight for the first time. Did you notice it from when you first received your 921 or did this happen after a period of time? Was your unit retuned fixed?

    I also have the blue line down the middle. Sent in the first box for a replacement. My replacement is also now showing this problem as well(supposed to have been screened for blue line problem). The first box didn't seem to have the problem for the first month I had the receiver, then it became pretty apparent. I tried to record some material with the problem line. Was able to capture it, playback showed it last night. This morning checked the playback and the line was gone again. Either my switching between SD/HD cured it for now, or it has something to do with the receiver having been on(Video output) for some time period. Suspecting this may be a thermal problem with one of the chips in the system. Problem only occurs in certain scenes with darker backgrounds and bright faces in the middle of the screen. Going to monitor to see if this box continues to do this before sending back again.

    My 921 was sent in for it's "blue lines repair" and I've had it back for well over a week now. I can honestly say that I have not seen the multiple blue lines visible against a dark blue background as before.

    Unfortunately, I can create the single blue line in the middle of the screen. To do this, simply switch between SD & HD modes and you should be able to see this clearly. While I'm not sure that this affects DVI output, it does appear with component video and is not present with SVideo.

    For now I am using HD (1080i) for everything, despite the fact the my Sony 65 XBR2 scaler is better than the 921 scaler. It's not worth slightly better PQ with SD to have a blue line down the middle in HD mode later IMHO.

    This sounds alot like a software problem.

    I leave mine in HD mode all the time (or used to, before a corrupted download killed it), so I haven't seen this problem.

    I see the same thing if I hit the HD/SD button and the line down the middle appears to be a software problem, not hardware. Usually I run 1080i through component out and if I want to see 480p then I dive into the menus to set it to 480p, not hit the hd/sd button. It would be nice if hitting the hd/sd button worked correctly.

    Um, 480p isn't SD though. SD by definition is 480i, which is what the HD/SD button changes to.

    Everything except 1080i and 720p is considered to be SD.

    Bob, my understanding is that 480p is considered "Extended Definition", not standard definition.

    Dish is still looking at my "green line" and "red line" problem. The dealt with my blue line problem so fast, I assumed this would be dealt with in a like manner, but I am in "wait and see" mode now.

    Mark,

    I think the ED term has been applied to the capabilities of some non-HD televisions to supposedly show that they are better than standard SD televisions but I don't believe I've ever heard the term applied to programming. For example a DVD played through a progressive DVD player provides 480p resolution but I believe this is still referred to as SD material.
