I cannot watch anything on my TV. A red light blinks continuously on the control box. A blue light stays on.

Remote control model number?

DVR/Receiver model number?

Thank you for responding to my request for help.

LG TV 65EF9500, I don't see a number on the LG remote.

Roku Express 4K+. I don't see a number on the Roku remote.

Denon AR Receiver AVR-X6400H.

Denon Remote RC-1219.

ATT TV (now Direct TV) control box kit C71, Item number 60075 P27U3D.

Thanks again.

OK. You don't have DirecTV Satellite. You have DirecTV Stream. I will move your post to the correct forum. 

What "control box" has the blinking lights?

Is this an LG issue, or a DirecTV Stream issue?

The ATT TV / Direct TV control box has the red blinking light and the blue constant light.

The LG TV seems to be OK. I can use the LG remote to get to the internet and sign on to Netflix or Amazon Prime and watch a movie.

Thanks again for getting back to me.

Are you using wifi on the Dtv stream box?

If you go here it runs a diagnostic (make sure u are logged in)

Hello Ludwick, Thanks for responding.

I used the link that you suggested and it returned the message:

"we don’t see your DIRECTV STREAM Device online."

Maybe that is related to the flashing red light that is on the control box along with the continuous blue light.

I am on HDMI 1 just as I am on my second TV in another room. The ATT TV Direct TV is working normally on the second TV. I don't have Roku on the second TV.

I think their site is glitching right now b/c i got that don't see my device error as well. Is your Directv stream box hooked up via ethernet to your cable modem/router or are you using wifi? If u are using wifi try running an ethernet cable to it. I think the red light on the dtv stream box means an internet error. 

If that doesn't work use the red button on the side of the box and do a reset. Hold it down for like 20 seconds. 

Yes, I verified an internet error. I had to sign on again after the internet was restored. Now I have a little blue circle that is spinning in the middle of the TV screen. It has been spinning for several minutes. I turned off the TV and Direct TV, and then turned them on. The little blue circle is still spinning again.

No issues here. App and channels loading fine. May be a localized/regional issue.

I know I've asked you this before but are you using wifi or ethernet? If wifi try and ethernet cable----if that doesn't fix the issue do a red button reset.  Or maybe you are still having internet issues. Contact your ISP and find out.

I am using wifi. I started to run an ethernet cable, but the wifi and the internet are working.

Then I did a re-install of ATT TV Direct Stream. That took forever because of all the Google setup that they asked me to do.

Then I did a re-install of Roku. Roku took forever because I did not understand the online instructions.

During final testing of Direct and Roku I thought that they had failed again but it turned that I just wore out the batteries. With fresh batteries in both remotes, I tried for a half hour to find any glitches, but everything works now.

Thank you again for your feedback.

I’m having the exact same issue in Nashville

@Warnerblaster , did you the original poster's solution?

Red light continues to blink.  I have pushed the red button on side of unit.  Light goes off and then comes back on.
