Unit won't play claiming weak signal. Scan shows 5 green dots

A channel scan using the Roku app found 21 channels - all 21 had 5 green circles for signal strength. However when I would try to watch Live TV it would give me the weak signal message.

After trying everything I found on the forum I launched the Tablo app on my phone and performed the channel scan using it.The scan found 21 channels but not all of them had a checkmark next to them. I made sure all of them had checkmarks and after that Live TV was working again.

I had that issue tonight only one channel would work all the rest said weak signal and I went to rescan the channels and it said no channels found. I then unplugged the tablo unit, and waited 20 seconds and plugged it back in… Everything worked fine after that.

We’d like to take a look and see what we can do to help! I’ll send you a PM shortly with some next steps.

I’ve been having this issue since 2.2.27 beta was released…Tablo hasn’t been able to figure out what’s causing it. Both of my Tablos have been having this issue about once a week, reboot fixes everything.

I have the same problem and have tried all of the above. I tried rebooting, unplugging, restarting, everything. I still get the 5 green dots, out of twelve channels I have one with three orange dots and it comes in fine.

I have been using Tablo for years and everything has worked fine - even the dot system. This is the first time I get 5 green dots and get no station. Does anyone know how Tablo’s signal strength system works. Do these dots mean anything? They seemed to mean something in the past.

Suggestions?

Have you run and saved a fresh channel scan recently? The dots are reflective of the signal status at your last saved scan.

Not commenting on the “dots”, I have a similar struggle. Noticed other comments "been just fine for [period of time] suddenly great channel won’t work. I’m not absolutely confirming the issue is with tablo although I don’t see it on my TVs.

It’s odd it’s only later in the evening. Last week it was just a single channel. Now there’s two - weak signal, tablo1 doesn’t have an issue, so I’m going to have to confirm cabling. When I’m recording schedule will have minimal impact I’ll have to swap locations.

No, you’re not alone, but there are so may outside variables to take into account - most were never aware of. :frowning:

Are you using a pre-amp on the antenna? This boost signal and noise. So having 5 dots may mean strong noise and signal, but not necessarily great reception. I wish Tablo would allow you to bring up a live Signal Strength (or better yet SNR) dialog for an individual channel to allow you to adjust the antenna or try different amp combinations. I think they use the Maxliner MXL692 tuner IC, so not sure if that supports reporting of SNR over the I2C interface.

The problem may be atmospheric propagation, where signals from far away are being redirected by the hot air back down to your antenna.

I live NW of Austin, and there are 3 main channels that go out when it is over 95 during the day, and cools to below 75 at night. When I do a rescan, I can watch channels close to 200 miles away without issue. The 3 channels that say, “No signal” are actually getting co-channel interference, causing the channel to not be able to be received (analog days, you had two pictures received on the channel, digital days - it shows no signal). And with the repack, the co-channel interference has gotten worse…

Same here! I show 5 green dots and yet the Tablo says that the signal strength is too weak. Makes no sense. I’ve restarted (leaving in unhooked from everything for over 3 hours) reset it, uninstalled/reinstalled everything and nothing solves the problem. Hooking up a Tivo Roamio to the very same connection with the very same cables works flawlessly. Tablo is not ready for prime-time. Drops channels randomly, and randomly loses contact with my Roku box (All connected via Ethernet) Can’t get a hold of Tablo support so I will more than likely return it to the dealer.

This isn’t an MS Windows system… these methods will have little to no impact.

[note: uninstalling doesn’t necessarily remove configuration data… it’s often pointless]

Tablo technical support can look at the logs in the unit and determine what is causing the problems. If you contact them by email, and leave your phone information and when they can contact you, they will take care of you.

:face_with_raised_eyebrow: so they can dig deeper than the “customer’s error” no signal, or unable to tune or even weak signal and tell you what’s causing the problem… when nothing else in your house has issues getting a signal or tuning or a strong enough signal with the antenna and cabling setup? via these secret logs? :neutral_face:

I am not sure why users can’t access the logs (it would have definitely helped me when I had problems), but you setup your Tablo for remote access, and they can review them. Tablo techs have connected to my unit and figured out why I couldn’t get guide data for several channels (it was a problem with my zip code).

When I email “the tech” about new channels not yet in my guide ( waited 2 weeks), I noted I’ve been through this in the past… I"m replying to an old email – yes I’ve re-scanned time and time again – please don’t send me a boilerplate response. With plenty of screen shots of everything.

When they, of course did, I just replied back the same… “the tech” eventually responds

I went through your Tablo’s logs but strangely enough, I’m not seeing channels 13.4, 13.6, and 16.6 in the lineup.

Since I will need the metadata of these channels from the Tablo to send over to our guide data provider, please try running a new channel scan.

Soo, I try to help… (knowing no matter how many times I scan it won’t add guide data!!}

I have 2 devices, those channels are on device

I did a rescan this week since I had a (different) channel move Tuesday…

What logs? I didn’t put it in “remote access mode”. The channels on my tablo aren’t “hidden” in secret logs btw. start here: http://tabloIP:8885/guide/channels

Now let me back up, I’m not saying tablo techs are, well I’ve had less hassle getting assistance with getting guide data straightened out prior time.

I’ve called to add a tablo to my account, got through within 10 minutes and was over in a few minutes.

I’ve also had tablo tech support respond -

We have had a look at the log your Tablo sends to our database;

Of course then do data mining! saying -

it seems that the Tablo has been experiencing frequent reboots due to the hard drive disconnecting while it is being recorded to. As well, the Tablo log shows the hard drive as being 0% used. It seems as though the drive may be beginning to fail.

Which my drive failed no test. I copied everything to another drive - no read error. Connected it to tablo, same problem. Copied everything back - no write error. Reset tablo – drive and tablo worked flawlessly since.

:roll_eyes: 2 bad drives - 1 good tablo / 2 good drives - 1 funky tablo :roll_eyes:

Do you live in the Lakeline / Ceder Park area? I tried helping a friend some time ago and had problems. She didn’t have a window where it was needed, did not want to have coax running along her baseboard. Problem was mostly all the channel 7 (FOX, MOVIES, BUZZR, DECADES,METV). She decided to stick with cable. I have the original Tablo quad and use wireless.

I live in Leander - about 6-8 miles north of that area. I pickup Channel 7 really well with a ClearStream 4MAX, Juice PreAmp and it is split to two Tablo DVRs & a TV. I stream the TV channels from the Tablos to 7 TVs.

Please do! We just purchased the Quad and have to use WiFi and am having same issues. Hubby wants to return it! TV didn’t have any issues with just the antenna!!!

This is an old thread, you’re likely better off to start your own thread to get help. Or just open a support ticket directly with Tablo Support.
