green screen when exiting comcast dch 3416 dvr

Has anyone gotten a "green" screen when exiting the dvr? My Panny th50px75u screen goes completely green when I exit or stop a dvr recording. I've ckd the inputs on the panny, and talked to comcast several times, even had comcast come & swap out the box today, since they can't explain the reason. In order to reset the picture, I've had to unplug the cable box for 1 min, to reboot it, then plug it back in, to get the cable & picture working. The cable man said I need to update the "firmware" for the tv, since the newer tvs are not always compatible due to the hdmi ports, and that motorola can't update their new dvr's fast enough to keep up with the new tv's. I then talked to Panasonic, and they said they'd never heard of having to update firmware on this new tv, and the prob was most likely with the cable box, since it wd reset after being unplugged. I think the prob was with the other box too, so will wait to see if this next one (same model) works. In the meantime, I'll have to rerecord my programs, since they all went with the old box. Any one know of this problem?

What type of cable are you using from the box to the TV?

I'm using an HDMI cable

Is this the one Comcast gives out for free? That cable has become an issue with newer sets. There is apparently a handshake issue where it gets stuck in the middle switching between HD and SD. DTV has the same problem with theirs that comes in the box.

So far the only solution is to buy a better cable or use component.

I supplied my own HDMI, good quality, as COMCAST does NOT give them out. They only supply component cables. As for the green screen, the new (swapped box) has not been a problem yet. However, if it does happen, I guess I'll just unplug the cable box again to reset it. That worked on the previous box.

Well, I'm glad to see I'm not the ONLY one who has now seen the green screen on their tv.

I have a brand new Sony KDL-46XBR4. This is the 120hz HD 1080p set. It is hooked up to a brand new comcast box (it even had plastic across the facia so I know it's new). I am using the HDMI connection with the Monster cable 1000 or whatever that highest speed $ 120.00 cable is (which now, I realize is overkill since the cable box will never use it, so I will reuse it with my blu-ray player when it gets here).

Anyway, on two occassions, I've turned on my tv to find a solid nuclear green screen. I tried shutting off the TV, the cable box etc. and it's just a field of green. The only way to get it to stop is to unplug the cable box and then plug it in. I bought the TV 1/19/08. Today is 2/19/08. That's 2x in 30 days.

I sincerely doubt it's the TV. Gotta be the comcast cable box.

Anyone else seeing this issue too?

It is the box. I'd keep swapping them until it works. I have the older model 3416 (yellow clock) and I have never had problems. I have a Samsung LNT-4695 and use the $124.99 Monster HDMI cables. I get the typical 2-3 second switch-over from SD to HD, but never get a green screen.

Motorola DCH-3200.:banghead:

The first one had a bad card or something. Sound was clipping in and out. This one was brand-new. I am hooking up the component cables to reuse the $120 Monster HD cable for my Blu-Ray player arriving tomorrow so maybe the issue will vanish. If not, will switch the box.

Couldn't resist seeing how good this sony XBR4 will look with blu-ray, so I found the Sony blu-ray with 10 discs at WalmartdotCOM for $348.00Link to it through wwwdotDealcatcherdotCom :banana:

I have NOT had a problem with the total green screen since I got another new cable box a few weeks ago. Both were brand new, latest model & latest firmware dct 3416 (the one with the wide rectangle window) and 18.32 firmware.

I have the same problem with my sony kd-34xbr970 and moto 3416dvr. They replaced the box twice with brand new boxes and still no picture with hdmi. I have come to the conclusion that it is a firmware or software problem in the reciever that creates imcompatable issue. Only way around it is to use the component cables untill this issue is resolved with the firmware. In other words we are SOL !

First let me add that the $6 HDMI cable you can buy at www.monoprice.com is as good as any Monster cable. This has been proven time and time again so don't waste your money on those over-hyped cables that can do NOTHING more than a monoprice cable.

Now on to the problem. In many markets Comcast will not support HDMI connections because of many compatibility issues, HDCP issues and the like. In many cases it is the box but the whole HDMI handshake thing is problematic at best. The best and most reliable connection solution for any HD cable box or satellite box, for that matter is component. As there are no handshake nor HDCP issues and the connectors are tried and true, component is the best solution. Be aware that component does and will send the same HD signal as HDMI does the difference being that it is analog rather than digital but that is the only difference. The recommendation/solution is this - take back those expensive Monster cables, get a refund, then get a set of component cables and either optical digital, coaxial digital or analog audio cables (which can also be purchased at monoprice) connect them and your problems should be solved.

There is NO better HDMI cable, that is a misnomer. HDMI cables either work or they don't (for all intents or purposes) and changing or upgrading these cables are not the solution. Be vary aware of sales hype regarding HDMI cables and search these forums for testing results concerning HDMI cable quality. THERE IS NO DIFFERENCE between the highly overpriced cables and the ones that can be purchased from places like www.monoprice.com for about $6.

he's right. I bought a cheap hdmi cable from sam's club and it works fine. The prob is the box. I went thru all the same stuff you're experiencing with my pan th50px75u. By unplugging the cable box, for a min or so, you WILL reset the dvr, and it shd work again, i.e. no green screen. But it will prob keep reoccurring. I then swapped my box, a new one for a new one, the one with the rect face, latest firmware, and have not had any problems with the dvr since. I've found that if you don't push the buttons on the remote too quickly when using any of the dvr functions, the cable box seems to respond better. Get a a new cable box, don't listen to any of the rubbish comcast? or your cable company tells you, and see how that goes. My comcast guy told me my new tv's firmware was not compatible with cable hdtv. I called panasonic and they laughed at me. The prob is NOT your tv, IT'S the cable box! Good luck.

The latest firmware for your set did not have ANYTHING to do with the HDMI connection-- it is for sure your cable box/signal problem.

Nevertheless, it is a good thing to verify that you have the latest firmware for the TV installed.

I found that if you hit the My DVR button it gets rid of the green screen and resloves the issue without unplugging the box

Hitting the MY DVR button right after the screen appears has worked for me a few times also.

This is a handshake issue between the TV and STB.

This should be able to be resolved by manually typing in the number of a high definition channel and forcing your tv to renegotiate the connection.

Also try cycling through you're tv connections again to prompt the renegotiation of the connection.

TV I expereienced green screen with is Samsung 5076s DLP using HDMI connection.

Again, gentlemen, if you use component instead of HDMI, none of these things will be issues. Since component is a analog HD connection there is no HDCP and/or handshake issues, just pure HDTV watching bliss...

Yes and 2 additional conversions.

Unfortunately the stb has to downconvert to analog to transmit along the component cables, then the tv has to reconvert the analog to digital to display it.

For picture quality, unless you're adding a line doubler, less alterations to the original signals = better overall quality (however the difference may be imperceptable depending on your setup/source/eyesight/etc....)

I've gotten the green screen to come up a total of three times now. I don't remember how the first instance of it occured. The second time it happened was when switching from one channel to another (using the remote to go to another channel). The third time it happened was when exiting the VOD.

Whenever I get this green screen, no button on the remote works. The box then resets on its own. I see that in this thread someone mentioned pressing the My DVR button. Someone else mentioned typing in a channel to force the box to re establish a connection with the HDMI cable. I'm just wondering if there is something that I am not doing right since I can't do any of these things.
