Hdmi with other tvs

is there a fix yet for the hdmi problem. when i play the tv hub on the downstairs tv everything works, but when i use it on the tv upstairs nothing comes on thru the tv  i ve tried to set the audio/video output to auto but it doesnt help . i have the latest firmware

Are you sure the failing TV is set to see input from the HDMI port?  Since the hub works on one of  your TVs the problem isn’t in the hub. 

i ve had it on the htmi channel a few times but it takes alot of pulling the power cord out and reconnecting everything which cant be good for the box . it works first time on the tv downstairs so its not a problem with the htmi port and the ps3 works upstairs without a problem using the same htmi lead i ve been using for the hub
