Re: 3 second blackouts

said by andyross:

When you used the component output, did you DISCONNECT the HDMI cable? Leaving it connected can still leave it active and cause re-handshaking issues.

Yes, I sure did.

Okay, so I moved the DVR down to the other room where it is connected to about 8 feet of new wire coming directly off the new groundblock/splitter.

After giving it about ten minutes to settle down, you can see from the images above that the levels are much, much, better. I don't have time just now to sit there for the next hour and wait to see if it is going to black out again; that may have to wait until tomorrow.

Also, in response to an earlier question, the status screen indicates that my RNG200N has a 465GB hard drive.

No, it is the Cisco RNG200N.

And, it turns out that the signal levels are not stable no matter which location in my home I hook it up to. Sometimes it shows Status: Locked, Level: -5db, S/N: 36db. A few minutes later it is back to Status: Unlocked, Level: -20db, S/N: 0db.

I am guessing it is a bad box and ComcastSteve seems to agree. I went to the office an hour ago (it is just 1-1/2 miles away) with hopes of exchanging it, but there was a line of at least 10 people and I didn't feel like waiting.

Maybe tomorrow morning...

Hello Carmine,

I have experienced the same problems. I have already replaced (exchanged) my TV and also audio/video receiver. Also, I have changed all of the HDMI cables. While watching live or recorded programs from the Comcast DVR (anywhere) cable box, the screen goes totally black for 3-5 seconds. It happens randomly and can be twice or five times in one hour. The picture always comes back and we never lose the sound. This never happens on a DVD. I am ready to contact Comcast and request a new cable box. This problem has been occurring for about the last two months.

Your HDMI cables are fine. Replacing the box will not fix the problem. ALL Anyroom RNG200N using HDMI will be affected by this bug. The recent R27 software update does not fix this issue.

It's either a HDCP handshake issue or a bug with CEC implementation.

If the timeline for fixing previous problems is any indication, don't expect a fix until next summer. Don't you just love this new software guide? It's Comcastic!

we already went over the issue with the hdcp handshake blankout, and after i tried component cables the issue went away. the OP did the same thing but the issue continues to occur apparently. OP wants to change out the box to correct the issue of the box not being able to lock onto the signal.

True; switching from HDMI output to component video and audio cables (the five-wire variety) did not solve the problem. And, the other poster's comment is on target: it may happen once every 20 minutes or three times in a span of five minutes.

Always the same; the screen goes black and audio is lost. The event lasts for two to three seconds and then everything returns to normal as if nothing had happened.

I will swap out the box and see if there is an improvement.

yeah that sounds like a loss of signal which is shown by what we discovered yesterday in the diagnostic screens. good luck.

Picked up a brand new RNG200N this morning from the local service center, shrink-wrapped and still had the clear plastic protection strip along the front bezel.

Installed, powered up, provisioned/activated, and took the first two screenshots above.

Waited 30 minutes or so, checked again, and as you can see, I am having the same problem with signal strength, s/n ratio, and locked/unlocked status.

I haven't watched enough TV yet to know if the blackouts will still occur, but I expect that they will. Waiting for ComcastSteve in the Direct forum to suggest the next step.

Like I said it's probably bad cabling causing bad signalling. I'd suggest having a tech come out. I'm still not a fan of how your location is wired, as I said before I perfer the branch method which is a single wire going into the house, connecting to a three way splitter, one peg going to the cable modem, one peg going to the voice modem, and one peg going into another splitter where everything else connects to. I got the hardware if you want me to send it up to you or I could do it myself if you want and thus avoid a possible charge for a service call.

This is an known issue with the RNG200N box. More specifically, the new software guide. Hopefully Comcast will admit this to you privately before you waste any time replacing your wiring.

The only way to fix this is to replace the box with a RNG200 or one of the older SA8300 series. Otherwise, you will have to wait for a software fix.

but to replace the box with an older piece of equipment will be a death sentence for all of the new features rolling out such as anyroom dvr, guide 2.0, guide 3.0, and so on which wouldn't be compatible.

Well, no one is more surprised than I to have to report that we watched TV for several hours last night and did not notice a single blackout of the type this thread has been about. Of course, my wife is a college football fan and tomorrow is Thanksgiving Day and we'll have lots of TV viewing in the day's lineup, so we'll see what tonight and tomorrow brings.

If what Stanley said is correct, could it be that the replacement RNG200N I installed has an older version of Guide loaded into it? Does anyone know how I can tell? It certainly looks the same as the previous one...

Also, I don't know if Stanley is referring to the same problem. My blackouts were both video and audio, lasted two to three seconds, and occurred at any time while watching live or recorded TV - in the middle of a program, the middle of a commercial, etc.

Pretty sure that if you get anyroom dvr they need to give you all new boxes anyway. guide 2.0 is when?

no the RNG200N and everything that came out during that same time supports AnyRoom DVR. Comcast said the 8300HD doesn't have the memory and processing power for guide 2.0/3.0 which also includes AnyRoom DVR and I think the fact it doesn't have ethernet doesn't help either. Guide 2.0 is sometime in 2012.

I'm just nervous about this issue occuring at the worst time and letting you and your guests down. The guide version that was originally on the box being different wouldn't matter since it would simply download the latest software available in your area upon bootup. I once picked up a shrink wrapped HD non DVR box and hooked it up and before I could use it it downloaded the S25 guide. If you ever press the power button after the time shows up the first time, APdL appears on display and that indicates it is checking and downloading the latest information available on the headend like a checksum.

It definitely did the download after I installed and powered it up the first time. Took 5-10 minutes as I recall.

So, we'll see what it is like tonight and tomorrow. Meanwhile, still waiting for ComcastSteve to let me know what he thinks may be causing the funny signal levels and unlocked status.

The following link points to my guess for when guide 2.0 will be available:

»Re: On Screen Guide 2.0 for SA Areas - Looks Good!

I think in SA/Cisco markets AnyRoom DVR functionality will only be available using the Cisco RNG 200-N as the host DVR. When this box is used for AnyRoom DVR functionality it uses On-Screen Guide 2.0 and currently it is the only set-top box to use it. In the future, On-Screen Guide 2.0 will be downloaded to other RNG series set-top boxes and the more recent Motorola set-top boxes.

It would be a good idea to check out the other posts in this thread and see if any of those suggestions help with the issue you are having. If they do not we will be happy to assist you.

The 3 second picture/sound is caused by the RNG 200N. I went through 3 of them and they all do it. This is a known issue that has yet to be resolved. Go to your local office and see if they can swap it for a SA8300 HDC set top box. Your problems will be solved.

Strange. I haven't had this issue at all. Only thing similar I was having was between changing certain channels, which was 100% resolved for me when I switched over to component cables.

I'd never replace the RNG200N for an older box for several reasons, such as the RNG has a 500GB hard drive compared to the 8300HD with a 160GB hard drive, the RNG200N supports more future features Comcast is implementing such as MyDVR remote programming, iPad applications, guide 2.0, guide 3.0, Anywhere DVR, and so on and so forth. To exchange for an older box would be a stupid thing to do in my opinion as the older equipment do not support any of what I mentioned above. I understand that some people are having trouble with the RNG200N boxes but I would simply recommend being patient while the kinks and oddities are worked out

The SA 8300 HD & HDC DVRs are scheduled to support MyDVR remote programming and iPad applications with the merged release of Phase 2/Phase 3.

The following quote is a post from Comcast's Ted Hodgins "New Guide for Scientific Atlanta Cable Boxes" blog. Please note the date of the post and the fact that the schedule for Phase 3 has slipped from 2011 to mid 2012.

quote:
Glad to see that you are paying attention Russ!

We were able to actually pull the myDVR feature (remote DVR access) forward into the non-RNG DVR's as well, so that is a very positive change. It will be part of phase 3 and expected this year.

The SA 8300 HD cable box is a newer box and will be able to support these features.

ah ok. i guess he must have forgot what he said back then when he told me differently. my point is still there that it wont support other new features that Comcast is rolling out in the future because of the lack of resource memory.

FWIW, my problem with 3 second blackouts went away when I swapped my "new" Cisco RNG200N for another "new" Cisco RNG200N. I say "new" because I don't really know the status of either box; the replacement was shrink-wrapped in plastic and had the plastic protective strip over the front panel - I don't know if that means it was factory-fresh or just refurbed.

The original box was installed on November 15 and acted up right from the first evening. I made the swap last Tuesday, the 22nd, and haven't seen a blackout since.

Fingers crossed...
