TV-21T Box Won't Wake, Have To Reboot Every Day

[Drdul]

I've had a TV-21T box since late August 2024. I worked fine up until a few days ago. At the beginning of March 2025 I encountered a problem where the box wouldn't wake from "network standby" (blue LED), and it has now become a daily problem that is only resolved by rebooting the box. Here's what happens:

• Box is in “network standby” mode (blue LED)
• Pressing the Home button on the Telus remote doesn’t wake up box as it used to
• I have to power the box off and power on again (I use my LG TV remote to do this as it doesn’t work with the Telus remote)
• Box starts up, screen with animation, LED flashes white
• Message “Active Internet connection established” (the box is connected to the router via Ethernet)
• Box works as it should
• Next day, rinse and repeat

I have tried the usual troubleshooting steps with no luck. Nothing about my system has changed, and the TV-21T box worked fine for 6 months, so I'm assuming there was a software update on the box that changed something. Has anyone else encountered this problem, and if so, were you able to resolve the issue?

I also experienced these issues. I am on my third tuner. But I thought to plug in the tuner not working into the new power cord that arrived with third tuner, and it woke up right away.

For the past 2 months I have been saying, get a new power cord. I have proven that is the problem. You can ask for a new cord or go to amazon and buy one, I did, leaving the supplied cord for backup.

Thanks, I'll investigate the power cord if I can't resolve the problem, but at this point it appears to be related to waking the box from "network standby" mode.

To add some more detail, the problem begins with the box in “network standby” mode (blue LED). Pressing the Home button on the Telus remote turns the LED light white on the box, but it doesn't display the "home" screen on the TV. The screen may be blank or the Telus logo may be briefly displayed on the TV then the screen goes blank (and throughout the LED remains white). I usually have to power the box off and power on again, sometimes not, but it all ends with the box booting up (screen with coloured circles animation, LED flashes white) followed by messages “Active Internet connection is established” and “Telus remote connected.” Then the box works as it should.

A final post to close off this thread. I bought a new power cord/supply to replace the stock power cord, and have been testing it for several days. The TV-21T box has worked flawlessly with the new power cord, so as @Rocky3 suggested, it is the solution. I didn't want to get a replacement power cord from Telus as I figured it might fail after six months like the original one did, so I bought this one from Amazon for $13: https://www.amazon.ca/dp/B09W8S3FBV. It is more robust than the stock power cord – the power supply is larger and the cord is thicker – so I am optimistic that it will not fail like the stock one did.

Thanks for the Amazon link on the power adapter, and to Rocky3 for the earlier tip on this issue.

Our box after 6 months now won't boot up about 50% of the time. After an hour on the phone doing the diagnostic dance we have another T21 android package on the way in the next 3 to 5 days.

I was curious if just replacing the power adapter would work, and it just turned up (Amazon same day delivery, feels so bad it's good etc) and yep - all works fine again.

We'll keep the new box when it turns up, return all the old things and just use the more reliable oem power adapter now I guess.

Telus should probably do something about this really..

My new purchased cord has not failed once for about 3 months, I admit the test should be 6 or more months.
