What I see, mostly on Wednesday's so far (I think) is that if I try to record on Fox HD (Hell's Kitchen) and CBS HD (Survivor), they are next to each other in the guide.

What happens is it seems like if I'm on CBS already, it will record Survivor and not Hell's Kitchen. If I'm already on FOX it will not record Survivor - they will show up grayed out. If I tune to the channel that is not recording, there is no picture, just black screen or maybe another channel like ABC.

It's odd... I have the box set-up using HDMI and have not had any issues with the box to date. This has happened three weeks in a row. First two weeks were no Hell's Kitchen and so this week I thought I'd try to be on the Fox channel and it dropped the CBS channel. The other things was that once Hell's Kitchen stopped recording at 10:00pm (it was 2-hours), the Defenders on CBS recorded fine in HD at 10:00pm but while Hell's Kitchen was still recording at 9:00pm Criminal Minds did not record.

I went to my son's room and he has a 42XX HD box and all the channels were there so it's not my incoming feed is it?

The other thing is that i can drop the non-HD channels and record the show that did not record without issue.

I have the main cable feed, no splitters only home run connections going to the 8640HDC, HDMI going from the 8640 HDC to my Onkyo TXSR705, HDMI from Onkyo TXSR705 to my Panasonic TH50PX75U.

Thanks for any advice - the box has been rebooted dozens of times and the trademark reinitialization signal was sent out but then we had a town wide cable outage so maybe it got messed up again?

It sounds like your 8640 isn't running well on your version of ODN (Mystro OCAP Digital Navigator) 3.2...which has been true in many regions. I'm hoping to trade up from an 8300HDC to the 8640 soon, but our area hasn't been getting any new 8640s because of all the major issues they ran into - we also have ODN 3.2.

Once ODN 4.0 is out, and better yet, 4.0.24, your 8640 should settle down and tune and record as it is supposed to. This is, if the other "stack" software that runs each type of box in your region is also working correctly. Currently, ODN 4.0 is being tested by TW employees in our region, and two techs I spoke with this morning said it is still very buggy. So, it looks like we aren't out of the woods yet.

The black screens you reported are familiar - after a power outage and system outage in our area last week, our 8300HDC did very similar things...most channels wouldn't display, only the guide and menu, while our other MDN 8300 ran fine. After rebooting it and 3 calls to tech support, I think what was going on is that somehow the 8300HDC wasn't getting authorization to display content. I learned that it won't even playback recorded events if it doesn't have a valid signal from the headend. So much for thinking I'd just watch recorded shows during system outages. One fairly saavy tech support rep told me that if a box is rebooted during a system outage, it can end up like ours. Might be something in the rebooting process that isn't getting all the authorizations clear, and you lose some channels, or all, as a result.

Sorry you're going thru all this - you're using a box that is still a work in progress with the current TW software in your region. It should get better soon, or you could swap for a box that works now, and swap again once 8640s work smoothly in your region. I doubt the issue is in your wiring. Too widespread, from what I understand. Too bad TW doesn't enable us to archive to and restore from external HDs, which would make box swapping far less painful. I understand one competitor offers this as long as the box is replaced with the same account number.

Regards,

Christopher

Our division has ODN v4.0.2_4 and I've noticed some quirks of it. Mainly in regards to channel changes.

I have ODN 4.0.2_4 - not sure when the update was but maybe that was the start of the issue. Any other thoughts? If I tune to Fox and go one channel up CBS will be black (neither channel is set to record). Then if i go to another channel and step back or type in the channel it will appear.

I am at a loss.

Orion, I noticed your sig says that you have a WD drive "in limbo". Why not just transplant it with the OEM drive? I did and am enjoying 900+ GB of recording space. Plus you don't need to bother with an enclosure and additional wires. The only caveat is you have to be willing to perform surgery on the set top.
post #215 of 418
Never considered it actually... Does the "stock" software that drive the DVR reside on the existing HD? If you swap out the drive does it boot up normally or do you have to load something?

What about my other issues... any thoughts?
post #216 of 418
Can't comment on you other issue because we don't have that version until next week.

You need a bare drive. All I did was swap a bare (formatted) drive into the unit and let it boot up. It downloaded and installed the current version our division has. Just be aware that in doing so, you may have to break or remove a tamper seal.

You are not alone... hdtvfan2005 is reporting black screen on channel change as a 4.0.2_4 issue in San Diego as well.

Seems to me that I used to have that problem every now and then with SARA!!!!!!!!!! I haven't seen it on MDN (on 8300HD box).
post #219 of 418
For those of you who got the ODN 4.0.24 Navigator Update and are experiancing the Black Screen when channel changing, you should fill out a Navigator feedback form here:

http://www.timewarnercable.com/north.../feedback.html

Don't forget to include your box make and model number, how often it happens, and what you need to do to make it go away.

I get it on all my ODN boxes, and I really can't say what is causing it, but it's not a signal issue. My SnR levels are fine.
post #221 of 418
How do you check you SnR levels? What range is considered good? I'll post mine once I figure out how to find them. Are they in the diag screen?

SnR levels are in the Main Service Menu, but I don't think that is the problem. It sounded like a classic symptom of poor SnR, but too many people are reporting it as a glitch.

If you want to check your SnR Hold down the Power button on the set top until the Power indicator flashes, then release and press it again. Acceptable levels are within the tolerance of -7db to +7db with 0db being the détente or optimal level.

Those numbers are absolute signal levels (in dBmV), not S/N. S/N should be >35dB (spec may be 33 or 34dB, but 35dB or greater is definitely safe).

For QAM signal levels, the boxes are spec'd down to -10dBmV, but the TWC standard is -8dBmV. As you noted, between -7 to + 7 dBmV would be a good safe range to be in.

For good reception, both level and S/N specs must be met.


On the 8600s, you can find level and S/N for the two currently tuned QAM channels in at least two places:
  • Page 7/37 in the OCAP Host diagnostics that you indicated above - Hold [Power] until it flashes, then press [Power] again. This works via the remote or the front panel.
  • Summary Page 1/2 of the main hardware diagnostics menu. This can be accessed by simultaneously pressing [Vol+] & [Info] on the front panel.
In the menus, you may also see Levels and S/N for FDC (Forward Data Channel), and Levels (no S/N) for RDC (Reverse Data Channel). These are for the "Out of Band" channels that allow the box to communicate command and control data with the headend. They are important but have no direct connection to video reception. FYI, the QAM video channels are sometimes referred to as "In-Band" in the menus.

Thank for correcting me there, I must have had a brain fart this morning thinking of FDC and SnR. He is right 35db is normal SnR. My range for I classify as good signal level was referencing the QAM Level which is Page 5 & 7 under the FDC menu on the 8640 - Sorry for the mix up.

I just swapped out my 8300HDC ( which I got yesterday ) for a 8640HDC. It sure feels alot lighter. After reading all these posts, especially BenJF3, I ordered a 1T Black Caviar HDD. I have my buddy Jeff Meier coming out to fine tune my 2 plasmas ( 42", 60" ) and the rest of my Home Theater components. I can't wait to have the xtra recording space cause I record a bunch.

I was going to suggest a Caviar Blue Edition as that is what the stock drive is. However, I can say I'm very pleased with the perforance of the Black Edition in this unit. I have not noticed any break up or studder and that could be due to the larger cache and faster speed of the Black versus the Blue. Bottom line, it's not much difference in price to go witht the top end drive.

Note: just remember to keep your stock drive somewhere safe so should the need arise to swap the box, you can.

A feature request I'm sending to Time Warner has to do with swapping boxes. The new 8600 Series have USB ports and I had suggested if the Navigator programmers could add a "backup settings" option. Then you could store all your box settings and recording schedules to a flash drive. This way if a box swap was needed, you could quickly and easily restore them.

THAT is an excellent suggestion. Let's hope TWC is smart enough to take it.

Doesn't appear to be any signal issue... at least at that instant on that channel (both tuners are tuned to RF channel 79, but may be on two different subchannels).

They still look great. As long as the level is higher than -8dBmV and the S/N is higher than 35, you are good. Your black channels are not signal level related.

555 MHz is the center frequency of channel 79. One of your tuners is still there. The other is now tuned to channel 81 (C.F. = 567 MHz). These are where the physical channels are located... not the display on the box.

Your cable wiring won't fix this black screen bug. It's more serious than that.

The Black Caviar was 88 BEANS, so I snapped it up. I'll keep the OEM drive in a safe place. Thanks for the reply Ben.

Yea, orion - your signal levels look about as good as they can get.

hdtvfan2005 is correct. This is a Navigator bug/glitch as it's being reported widely now. I suggested checking levels to people simply because a black screen is a very common signal level issue where the box cannot lock on and tune an SDV channel.

Absolutley - it's nice to narrow it down step by step. I posted in the TWC Direct forum on broadbandreports and they are saying:

Review of your equipment shows one of the cable boxes is experiencing significant signal impairment. In addition, the modem also shows a high number of attempts to address signal issues.

The division has been contacted regarding the delay in this matter being escalated to maintenance. As more information is received, I will advise.


We've been told that the issue was from the tap back regarding our speed issue. Our RR speeds are 1-4mbps during peak to 6-8 during off peak with Turbo. I don't know - I wonder if it's a combination of line issues and navigator bug. The TV tuning issue however just started about three weeks ago. My sons's box is an 4240HDC - do you look @ the S/N the same way by holding the power button?

Thanks again for all the replies.

We have this box in our bedroom and the light for the time/channel is very bright in the middle of the night. I only seem to be able to have the time show all the time or the channel . What I would like is for the screen in the box to be blank when the box is off and have the time/channel when it is on. I can't find a way to do that -- any help out there? Thanks

I can make it blank all the time but really do not want to do that.

Well - according to the tech that came to the house said it is a known issues and they are working on it in Binghamton. We will see - from what I could get detail wise is it's software related.

We'll see.....

Should you force a reboot of this new box if one hasn't been done in a while? You know, garbage cleanup, etc.

I guess the answer is YES, because, for some reason, it stopped obeying the schedule request to record Countdown With Keith Olbermann at 5:00 PM Pacific time for the last two days. No conflicts and recording log has no entry in it for record failure and stopped showing up in the list of scheduled recordings for the next week or so.

(I wonder of Billo the Putz or Glenn Beckerhead or Rush Limburgercheese got into my box.)

It was there, but was being ignored (I managed to capture the 8:00 PM Pacific broadcast, but that's not the point! )

Even a reboot failed to capture the series schedule glitch. Maybe because it was too low in the priority list (15 of 22)? Anyway, I deleted the series entry and re-entered it and moved it up higher in the priority list (now 2 of 22), and now I have it back in my list of scheduled recordings.

I have no idea what got hosed or why it got hosed.

I just got another 8640 this week. So far, so good as it does not revert back to 480i and there doesn't seem to be any HDMI issues so far. One thing I have noticed is that when I fast forward or rewind recorded programs, it doesn't show where you are in the program... it shows the info for the program that is on live tv at that time. Really wierd! Anyone else experienced this?
