now is it still doing this? or did this just happen one time?
does it do this on other inputs?like DVD?
what input are you using to watch tv? and what is hooked to that input? like direct t v or cable box?
unplug the tv and the uverse box from the AC plug and wait 5 mins then plug in the uverse box first then the tv and try again. let me know if this works?
i am glad this worked for you. if it does it again have the uverse box replaced.
