TV shows "No Signal" when hooked to cable. Cable has been tested with another TV and that TV works fine.

This sounds similar to my Vizio's second HDMI port; they sometimes become finicky after a while. You may have to just adjust and wiggle the end of the cable inserted into the TV; if it works, then make sure you don't even slightly touch it or else it'll lose signal again. If you have any other ports, try them instead; otherwise the problem may eventually get to an unusable point. You will have to have the port repaired or the TV replaced.

hook up how you want it to be and when turned on hold power until the second beep is heard ok :)

U get a channel numder and menu screen do show up?Not the tv,it the incomming broadcasting signal cable plug in or the cable box itself have problems.Tries unplug,replug the tv and the cable box back in like about an hour later.The tv will reset itself to the factory setting and the cable box should upgraded it softwares.Should work now.If have the same problems,tell the cable company change the cable box or check the incomming broadcasting cable wire with another tv,see the incomming broadcasting signal cable wire,with a new cable box,see if it work.

The cable box needs to be set to send different signals when using hd tv and standard tv. Usually a good setting would be 720p in hd and 480p in standard. The tv is working fine it is the cable box sending the signal. If you have another hdmi source such as a dvd player you may hook that up to show the tv is working just fine.

Purchased a x810 & everything tests out fine except TV signal sounds from cable box. We have the Comcast cable box connected to the 50" Samsung Plasma TV hooked up to Samsung x810 Soundbar all using HDMI cables. But we are not getting cable shows sound through Soundbar. Please advise

This problem requires you to test both the monitor and the signal input form you cable tv setup. Set the monitor up on a computer and see if it works properly. If it does then you may have a problem with the signal conversion of the cable tv to the monitor. It also could be a weak signal that drops below the monitors sensitivity levels. Have your cable tv repairman check the signal levels on your lines. Another way to test this is to hook up is with a different monitor to test your setup and see if it works. If after testing you find, the monitor does not work properly, then you need to have it serviced. Hope This Helps.

Had the problem. Turned out to be a defective hdmi port circuit board.

hi there, it may need some fine tune for the sony kv-27fs12 to be connected directly to cable jack wall. do some test. ty
