I have a 4-tuner Tablo that, on occasion, exhibits an unusual behavior. Unit is running 2.2.10 firmware. Rokus (1,2 and 3) are my primary “go-to” units. Two are wireless with APs inches away, the third unit is wired. Rokus all updated to new Tablo app.
With the new app, we can see an “Error: Weak Signal” message. (My 50+ channels all show full signal strength, and I get only a couple of random pixelization events a day – we live about 20 miles from the transmitters.
My job has me up before 4am and I turn on one of the wireless Roku equiped TVs while I fix breakfast. Last two mornings, I was getting the “Error: Weak Signal” message on all channels when trying to watch live tv. Recorded stuff seemed OK, but I didn’t stay with it long.)
This morning, (Saturday) I was up at 4am but don’t go into the office. Had the error message from within the Roku app, after channel selection. Multiple times and multiple Rokus. Since I had time, I also tried it on a PC. It came back with “Player Error” message and pointed to “weak signal” as a likely cause.
At this point, I did a power down reboot of the Tablo unit. Upon rebooting, all channels were behaving normally. No more problems. My recordings are done in 720p, 3mbs, so I don’t believe that I need a tuner to transcode recording output to the Rokus, which could possibly explain why recorded content played. Don’t suspect overheating is an issue as the unit sits on top of a cooling pad.
Any ideas as to why the signal magically reappeared on all channels after a reboot? Does this sound like it might be a problem with the internal preamp circuit in the Tablo?
