    posted this elsewhere, no responses so..

    A search didn't pop up anything obvious in the forums..

    I just installed a 942, and everything was working great, but three times since I installed it last night the system seems to be working, but changing channels I suddenly get no video:

    I can see the on-screen display when I change channels, and I get audio, but no video. Changing channels I again can see the channel info on the OSD, but no video. A check switch test passes fine. I see one green light on the front display (tv1 I believe).

    Anyone have any ideas what might cause this, or potential solutions?

    thanks in advance, and apologies if this was answered before, but I uncovered nothing recent.

    I've not seen or read of this happening either. It could very well be that your 942 is bad. Before you call Tech Support, please try the following:

    If you haven't already, try a "warm boot" by pressing and holding in the front panel power button for 10 seconds. It will take a while to reboot. If it doesn't come on by itself, power it on with the remote.

    If the warm boot doesn't help, do a "cold boot". Power off the 942 and unplug it for at least 30 seconds. Longer would be good. Then plug it back in and turn it on.

    I doubt that these will help, but it won't hurt to try. Your next step will be to call Dish. Please let us know what happens.

    I had a new problem show it's ugly head. I turned on (out of standby) the receiver, the software appears to be fine, menu works, guide, DVR list, show info, etc ... but no video/audo. Tried different channels, SD, HD, OTA, Recorded, nothing shows up. All the info looks good, but just a black screen for the actual video/audio. Definetly not an ouput problem since the guide, menu, etc ... shows up, but rather a tuner problem of some sort. I hit PIP and the windowed tuner works, I hit swap and it moved to main screen and now PIP is black. I hit the power button to put it back in standby and then hit power again, now no video/audio and PIP doesn't do anything. At this point I did a soft reset and everything came back. Very strange. Oh, about 15 minutes or so before this everything was fine.

    Rob,
    This is the second report I have seen of this problem. A reboot fixed that user's problem as well. I have not seen any reports of it happening a second time. Please keep me informed, and I will pass this along after the holiday.

    It has happened to me three times now. Each time I was watching OTA HD. I havent had it happen while watching other satellite Chanel's. I have to reboot the machine. I dont loose audio, just video. It seems to be happening more and more.

    count me in! After 283 update, it happened to me Nth times but mine is little different. watching OTA HD during inclement weather and the video drops out, try other channel/s, menu, info and the audio is very good but no video at all. A reboot/check switch will solve the problem at the times but for me, its not accepted as a fixed :nono:

    thats kinda weird-mine just started doin that yesterday also.I have audio and the channel banner but no video,even ota channels are doing that. The weird thing is that it is recording something at the same time its doing this and when I play it back through the dvr it shows the picture.

    for what it's worth, I have not had the audio / no video problem since it was installed. I'm hoping it was a fluke.

    It's interesting others are seeing a similar kind of problem though..

    Just an FYI, the problem I enountered may or may not be the same one this thread is referencing (which is why I started a new one). My problem involved loss of BOTH audio and video, not just video.


    Yes

    Thanks

    After 283, I've had the no video problem twice. Unplugging and replugging resolved the problem in both cases.

    Yes, I just had the same no video problem for the first time. I was watching sat, no DVR running, and through HDMI. TV 2 was not effected. Soft reboot put it straight.

    I have had the same problem since 283. I've seen both "video, no audio" and "not video, no audio". Soft reboot fixes it. Seems to happen when switching channels
