U-verse TV Equipment

New refurbished box is giving me this error message. Help

Just got a new tv receiver box and keep getting account unavailable message. Reset several times and same result

I have a Samsung tv and AT&T remote every button works on the remote except I can’t change the volume or mute the TV please help. I’ve tried re-pairing the remote and modifying audio settings but nothing works 

I've called the number for Customer Service and done the "Chat/automated response" thing and they are to no avail. One of my received power blocks has gone bad.   The system tests show good because the other receivers are all up and running.  SO automated chat is a no go.  

How do I add another uverse receiover to my accouny and where do I get one ISB7500 or equivalent

I need the remote code for my Insignia Fire TV F20 series. I've looked everywhere and tried all codes I could find. I couldn't find a specific one for a fire TV.

My wireless uverse receiver has bricked out on me . I need to get a replacement unit sent out to me, but I've had no luck with the phone numbers I have for customer service . Is there a number I can call and speak to someone directly instead of going through all the computer assisted crap . I'm old,

He added the box to my account and it still show unprovisioned. I ebonite’s my WIRELESS ACCESS POINT and rebooted the set top box and reconnected it to the network. The problem is still the same.

One of my wireless receivers doesn't work. I have restarted it many times but it still doesn't work. All I keep getting is a big red X on my TV screen. I need to replace it . How can I do this. Is there a customer service number I can call to get this done?

I’ve had ATT for 15 years because it’s the only service for my area and every night at 11pm the signal is lost. I called many times for help and they just walk me through the steps I already tried. I’ve called so may times and get told that my TV must be on a timer, or the walls of my house are mess
