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

I have a 4 tuner Tablo. Lately, I go to watch something and nothing will play. I get a weak signal message. I’ll go into my.tablotv.com and rescan. All selected channels show up as 5 green dots. The only thing that has worked and this is only for a short time is to unplug the box, wait a few moments and then restore power.

My Tablo is in a cool basement. I have a large antenna with a preamp on it in the attic. From my.tablotv.com, it claims the channels are all solid. What is going wrong? I can’t use it unless I first reboot.

My device has worked for months. Nothing has changed in the setup. Did the unit go bad?

Same issue here too, need google classroom assistance on this. Help is appreciated.


Remove the power to the Tablo for 30 seconds. Then reapply power, and wait for the Tablo to reboot.

Let us know if this works or not.

I had a similar event last Sunday. The Tablo started reporting Player error weak signal so I changed the physical channel to 3 others and all reported the Player error weak signal. After I reset the Tablo, operation returned to normal. I tried to reproduce the problem today but failed in several attempts. After the reset 1 week ago my Tablo has been operating completely normal.

Are you recording a lot of material simultaneously? In my case last week it was football on a Tablo Dual. So it only took 2 games and a request to play a different physical channel.

Any ‘Player error tuner unavailable’ errors reported?

Are you using a FireTV Stick?
Are you using WiFi?

That only works for a short time. I can’t trust my Tablo to continue working through a program. It may work for 20 minutes after the reset or a couple of hours, but it will stop playing and any attempt to tune to a different channel or the one it had been playing fails with the “weak signal” error.

I can go to my computer when this happens, go to setup and rescan. ALL channels have 5 green dots and report are good, but the Tablo box will not stream one because of a “weak signal”.

I have a 4 tuner box and have never received a “Player error tuner unavailable”. There are cases where two channels were being recorded and we were watching a third.

I use Roku to view programs. One is there latest model, a 4K unit. I have two. Both receive a “weak signal” error on the Tablo channel. All my connections are hard wired. I am not using WiFi.


Thanks for the reply. It appears that the only thing that we have in common is the use of ethernet instead of WiFi.

Perhaps something has changed with the signal strength. Would you mind giving me your latitude and longitude? (And the approximate distance to the transmitters.)

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.
