Cable box lights all on, no picture.

Hello, we currently have dvr boxes hooked up in three locations. The one in our bedroom was working fine until yeaterday morning. When I turned the tv on there was a red x. Iwent to reset the cable box and now it does nothing. The power light, link light, hd light, and record light all stay on. Pushing and holding the power button does nothing. I swapped out boxes and got the same problem for each of them, but only in the bedroom. What could my problem be? Any help is appreciated. Thank you!

TargetHero - What kind of connection is the bedroom- Coax or cat5?

Is the other end of that connection connected or is it loose?

If it is coax, you could have a bad splitter or diplexer/ If you cannot sort out your connections, it may be best to have att do it.

Hello, we have a coax connection that runs into a wall outlet. I triple checked the connections to make sure everything was tight. If the cable connection was the problem, would this be the cause of my problems? I'm not sure where the connection runs after the wall, so it might be best to call support on this.

Just to add on, I traced the line down to my basement and switched some cable cords around. Same problem. I pulled the cable wire out from the wall and plugged it into the box directly,  same problem. I reset our modems, same problem. I'm pretty sure this will be one for an att tech.

TargetHero - Good for you for not giving up & trying the power supply. THere have been a couple of those lately. I will have to add to the list of what to try.

Thanks for posting so that others can benefit.

When you say you switched out the power supply, what do you mean? The power cord or the surge protector? I seem to have a similar problem. I have 3 receivers and only the one in the bedroom is having this problem. DId you have to contact AT&T for a new power cord?

Same exact issue.  My surge protector was partially out of wall socket.  Plugged it back in and started working right away!  Thanks for posting!!

I have a wifi receiver, all light are on. Was watching tv pushed the guide button on remote and it flickered and looked like the guide was stuck but could change the channel and then it just went black. I have tried everything. Unplugged the receiver tried to reset it with the power button but nothing works. Reset everything. Any ideas?

My unit was apparently gearing up for a firmware update. It took about 5 mins before all but the green light went out. Then a picture with 2 gears and a progress bar appeared on screen. The update took a long time. I hadn't had that receiver connected to my regional gateway for a long time which might explain the long update cycle. Once receiver finished updating it power cycled off then on by itself and U-Verse Screen came on. Good luck!!!
