sounds like the avi board and graphic control is not working they are usually on the same power line on the main board. can you try the menu setting see if they come up on there avi ext1 etc.
It sounds like you are hooking the cable to the wrong input (digital instead of analog) or you do not have an analog input. If you do not have an analog input you could run the cable through a VCR to convert the signal to a separate audio/video signal and send it to the TV via an auxillary input. Without the model number I can't give you much more help.
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.
go to menu settings, find add/delete channel or programming or tuning. There should be an option that says "autoprogram" select this option and let the program run thuroughly. It will read and install all available channels. Do make sure tv is set to CATV and that it is NOT set on AIR.
It may be an internal filter on the tuner board or in the cable line. Otherwise it may be a firmware problem that is causing this. Make sure tv is set for CABLE and not AIR
YOU HAVE A BAD TUNER OR RF INPUT. IF YOU CONNECT THE CABLE TO THE VCR AND THEN USE THE VIDEO OUTPUT OF THE VCR TO THE VIDEO INPUT OF THE TV YOU CAN USE THE TUNER IN THE VCR TO CHANGE CHANNELS.
