Ongoing Signal Issues with Ceton InfiniTV 6 ETH

[Ixax]

I am opening a support ticket with Ceton and directing them here to see my info.

Ok, so you can see my background:
First I posted this thread:
http://www.thegreenbutton.tv/forums/vie ... =68&t=6866

Then I got lots of great info and help posting in this thread:
http://www.thegreenbutton.tv/forums/vie ... =68&t=6876

Now I am here. I'm thinking of this as the beginning of my Epic quest to overcome the ongoing issues with the Ceton Infinitv 6 Eth.

The AllCetonSignalsApp showed terrible signal info as expected:

From Windows Media Center I then reran TV Setup. TV Setup was unable to detect the TV signal so I could not proceed. I restarted WMC but that did not help setup complete. I reran the digital cable advisor and that did not allow setup to complete.

Went to Ceton support and redownloaded the Ceton infinitv setup app. Ran it and selected repair. Upon completion of repair allowed it to restart the computer.

Now all six tuners show as playing in the Ceton infinitv webpage for the device. The AllCetonSignalsApp won't run because all the tuners are busy. Once again unplugged the Ceton unit which set them back to stopped instead of playing.

Ran the AllCetonSignalsApp again...

Back to TV Signal setup. No worky. Tears may flow. Support ticket submitted with two logs from the Ceton diagnostic application.

[Ixax]

I manually installed firmware as directed by support. I did so from my networked laptop, not the htpc running WMC. (I mention this just in case this is a problem, though I obviously do not think so.) I restarted the laptop and then the htpc after the manual install just in case. I did not unplug the Ceton 6 Eth.

I then tried to run TV Signal Setup to see whether it would now complete... it would not.

The current AllCetonSignalsApp results...

Help.

[mldenison]

It looks to me like your signal level is way too low.

I'm running both a USB and an ETH tuner for 10 channels and I have no pixelation issues. I did have problems early on.

My cable setup is this: I have a 3 way splitter on the cable where it enters my house. One leg goes to my Comcast voip/router/modem. One leg goes to a 8 port amplifier which feeds all my outlets in the house. The last leg goes to a MOCA adapter. One leg from the amplifier runs to my HTPC where I use a splitter to feed both tuners. The output from the MOCA adapter goes to a MOCA splitter that feeds my two Echos.

My average signal on each of the tuners is around -2 to -3 dBmV. My average S/N is around 36 db.

I also replaced a couple of cable runs that were RG59 with RG6.

Either you're having problems with your cable run and/or signal splitting or there's something amiss with your ETH. Ceton support should be able to tell if the ETH has problems.

My ETH is only a couple of weeks old since I had to replace a 4 tuner PCIe card which pixelated badly on a couple of channels. Ceton was able to tell me my PCIe card was wonky.

[Paw Paw]

Those signal and S/N readings are way too low. Ceton spec is +12 to -12 dbmv on the signals. If the Eth6 is working properly then I would suspect a wiring issue or cable company problem.

Do you have other TVs in the house that are working? If so then I would suspect the wiring to the Eth6. Assuming that you have RG6 cable then the terminations and splitters are the probable cause.

Every 2 way splitter reduces the signal level be approx. 3.5 dbmv. a 4 way splitter reduces the signal by about 7 dbmv and an 8 way splitter will have about 14 dbmv of loss. Too many cable splits can cause the degraded signal. Also using an old splitter that is not designed to work with the higher frequencies that the cable systems use can cause problems. Your splitters should, as a minimum, be rated for up to 750Mhz and preferably up to 1,000Mhz.

Cable terminations should be the compression type. If you have any screw on ends or crimp on ends they should be replaces with quality compression fittings. Also do not use the cheap patch cables that come with come TVs and just push on to the threaded connector on the TV or Eth6.

I am on a Comcast system and do not use switched video. In looking at the Ceton ALl Signal output that you posted I suspect that you are on a switched system and have a tuning adapter next to the Ceton Eth6. I would carefully inspect the splitter that you used and the short cables from the splitter to the Eth6 and TA.

Hope some of this helps

[Ixax]

Thanks for the replies folks.

The signals were higher before the 6 Eth stopped working. (Meaning that at the moment, with no change of cables or connections, the system should be working better than it is.) You can see from the results of the latest scan that the tuner is not even "tuned". The system was almost working prior to whatever happened last night. Only some pixelated channels. While I was out last night something happened and the tuner could no longer pick up the channels. I could not even successfully complete TV Signal Setup in WMC. (Which I had done before. I was having intermittent success watching and recording some channels.) I submitted the diagnostic report to Ceton support and they told me to manually install a firmware update. So, I did, but if anything changed, I can't tell. My second post is the reply to them captured here so that I can provide the info in the code tags. Hopefully, Ceton support's follow up has better results than their first response.

[Ixax]

Ceton Support asked for activation of additional logging.
(results of three commands... The operation completed successfully. The WMC Receiver service was stopped successfully. The WMC Receiver service was started successfully.)

Then ran WMC and tried to see live TV. Could not detect signal on the couple of channels I tried.

At this point I ran the Ceton Diagnostic application. File is attached to support ticket.

Attempted TV Signal Setup within WMC. WMC could not complete it due to not being able to detect the signal.

The set top box has continued to function throughout.

[tzr916]

Do you have a modem or set top box connected and can possibly look at the signal information screens of those devices (give some model numbers maybe we can help). The signals shown on the Ceton tuners are WAY off. I am very surprised Ceton support doesn't immediately tell you to call your local provider out to set the signal right.

[Ixax]

If you go back and check the history described above (including linked posts in op) you'll see the Ceton was once working with the current set up. The Ceton support rep has (I hope) that information and so doesn't make that recommendation about the signal provider. I'm still hoping to make this work, so I'm hoping this is the rock bottom from which things will improve.

[tzr916]

If you choose to ignore those crazy bad signal readings you are getting on the tuners and don't opt to check the signals via other connected devices or by your service provider, then good luck to you!

Thanks for the good luck! Definitely takes it to get this working.

As others have said, eliminate that which you can eliminate from the list of possible causes. Signal issues creap up, I've had to rerun lines before months after setting up my system. Drove me nuts for about a week, but after I reran the line, everything was working as expected.

best thing to do is run a line from your splitter to your InfiniTV6 as a test (i.e. don't fish it through walls etc, just lay it on the ground if possible) and test the signal after running the new line. If the signal improves, you have identified your problem.

Another solution is if you have a known good terminal in another room, relocate the InfiniTV temporarily and check it against that terminal, if it works, again, you have identified your problem.

If both of those solutions don't help, you are now leaning towards it being a InfiniTV issue.

[blueiedgod]

How many splinters are there before the signal gets into the tuner?

Can you connect it directly to the feed coming from the cable line into the house?

[Ixax]

Came home from work and planned to check on things and it worked first thing. So, then went behind and tightened all the connections and then ran tests.

Not sure what the problem is, but the signal strength is there again. At least borderline. I already purchased the amp splitter I mentioned earlier, so I can add that in after hearing back from Ceton support and then see how the numbers look.

Ceton support was thinking it might be something with OOB Lock and I'm thinking that is probably better now too.

Lets see what they figure out.

EDIT... No signal at channel 680.

[smcmillan2]

Has your weather changed in the past day or two? I had problems with greatly fluctuating signal strength over a year ago. Narrowed it down to weather patterns (I'm in Metro Detroit area), especially when it got wetter, and had the cable co come out and run a new line from the pole to the house. While the new run alone did not eliminate the low signal it did improve it considerably, adding an amp (http://www.pctstore.com/RF_amplifier_CA ... tma28p.htm) has my signal level consistently between -2 and -4, SNR 35.5 - 36.8.

EDIT: Also, be sure to check your tuner temps (each of them when tuned to a channel). Didn't notice temps in the output you posted, others have had issues with their Ceton getting too warm to consistently maintain a signal. My USB 4 sits in the bottom of my rack in the basement, never had a heat issue.

[Ixax]

Just wanted to let folks know that we got it working. They never figured out what was causing the big signal drop, but it came back to being around -7 for each channel. When that happened, and we got it working sporadically again, then I moved the 6 Eth upstream and the readings jumped much closer to -3. Works much better with those signal readings now.

I think the 6 Eth post for the connection is probably to blame. Someone had pointed out that they can be tempermental. When I moved it I was very careful to tighten the cable and set it down with as little tension as possible on the post.

Thanks again for the help from you guys.

Hi Ixax,

Where did you download the AllCetonSignalsApp? The file was supposed to be here http://experts.windows.com/frms/windows ... spx#555788 but it is no longer available.

If you still have the app, could you upload it somewhere that I can download? TIA.
