Default Comcast - Green Screen

I just got a new HD/DVR cable box from Comcast last week after I got a new LCD for my bedroom wall. I'm having problems with a green screen that comes up. It seems to happen when I try to watch something on the DVR. In order to get it to go away, I have to unplug the power to the cable box and plug it back in.

TV - Vizio (I know it sucks, but it was cheap and I dont watch TV in my bedroom that much so I didnt want to spend to much on a TV)... hooked up via HDMI.

Anyone know what the problem is? Is it the cable box? I dont have this problem with the older Comcast HD/DVR cable box I have in my living room.

Thanks!

you try the box in your living room on the tv? See if it does the same. if it does, just go componant/optical audio and that should resolve it. Ive had issues with HDMI and the cable boxes. Is yours a motorolla cable box?

I experienced this very same problem just recently, however, it didn't happen under the same conditions as what you experienced. It happened when I was switching from one program at a commercial break to another program using the "last" button on the remote. The entire screen went green and then the box reset itself. Of course, that was one of the issues which I had tried to get resolved during a recent service appointment. They somehow made different solid colors come up on the screen.

You might want to see if the box resets itself when this happens. If it's happening on a regular basis, you might want to have Comcast come out and see if there is anything that can be done. You could of course always change out the box.

Yes, its a Motorolla... the new one.

It seems to happen when I am watching a HD channel then try to switch to a non HD recorded DVR show.

I'll try switching the box's and see what happens.

I didnt mean to knock it, I'm happy with it for the price. I just know that most the guys on here go with the better HD TV's.




I also dont like that when I change channels on this TV... from a HD channel to a regular channel... I get a crackling sound and the picture flickers for a second.

picture flicker be common, but the crackling sound can raise a hair. You sure it's not the cable box making the crackle?

It is the dumb boxes, I have had a tech out numerous times and switched boxes. They never seem to fix it, I have learned to deal with it. It happens every once in a while when switchng from an hd to sd channel or when you start hitting buttons quickly when using the dvr

I'm from the Bay Area also, with Comcast as my provider and the same Motorola DVR that you are talking about. I use a Vizio, (and I'm happy with it :P ) and I get that annoying crackling sound when I am on the HD channels.
This is no joke, I called Comcast about the noise, and the woman on the phone told me to simply turn the volume down. After I realized she was full of it, I did what she told me. I then told her I had no sound because my volume was all the way down and I needed help on fixing it....... she had no answer for it. Wonderful customer service.

Another friend of mine has the same problem with an LG Plasma. If we can find a way to stop it, we'll happily share the info.

I have had two Sony HDTV's (34 in. CRT and now a 50'' RP) and also have Comcast cable. I had the same problem, more often with my first set. I remember reading it could be "a handshake problem". So now I always turn my TV on first and wait for a minute or two and then turn my cable box on. When I shut them off I turn the cable box off first and the TV last. I have not heard the crackling noise since.

But doesnt HDMI give you the best HD picture? I apologize in advance for my ignorance.

I have tried both component and HDMI and could not tell one bit of difference in PQ. With SD or HD. I use HDMI now for the ease of connections, 1 small cable for audio and video. I even bought an upconverting DVD player just for the HDMI connection. I run my STB and DVD player to my A/V reciever via HDMI, then out to the TV with 1 HDMI. Behind my TV finally doesn't look like a mess with all the cables.

Just got my first green screen experience today. Apparently there's a few bugs that need to be worked out with these new boxes.

I hooked up the new motorolla box I was having the green screen/noise/screen flicker issues with to my TV downstairs (JVC). I didnt get the green screen, but I did still get the noise and screen flicker when I changed channels from HD to standard. So I hooked the problem box back up to the TV in my bedroom and now its not doing it anymore... weird!!! If the problem comes back, I'm taking the box back to Comcast to get a replacement.
