My mother gave me this tv and I am trying to connect it to my comcast cable connection. But it appears that this model tv may not accept channels higher than 99 channels. Even with auto chan scan/set-up and spaces for three channel digits, the tv will not accept chan 100 and above. My mother did not have the owners manual so maybe the tv (a 1999 manufacture) is not capable of more than 99 channels. Can you help?

I think your TV is made by RCA and it should go to cable channel 125. If Comcast has any channels above 100, you should be able to get them.
RCA TV's have a problem with the solder connections inside the tuner. This may be your problem. If this is the case the tuner would have to be taken apart and re soldered.

Connect the TV to the Comcast box using an HDMI cable, then set input on the TV to HDMI - that's all. You then select channels on the Comcast box , not the TV (although the TV remote can be programmed to change channels on the cable box)>
I assume this TV has no Audio In and Video In, from your Cable box there's an antenna out or cable out, connect that to your TV's antenna in, and make sure that your TV is tuned in to channel 3 or 4, try those two channels. You can only change channel thru your box, your TV channel is alway's on channel 3 or 4.
I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.
The RF Connector could be loose either because of bad solder connection or just that part of the tuner could be going bad in the TV. One fix or repair is too use a cable box to eliminate the tuner issue or borrow one for test, and or buy a inexpensive vcr and hook it to cable first then take the output out of vcr and run to tv tuner input. Or better yet, use Yellow ,Red, White cables (Composite video) and run it into respective inputs on TV if it has those inputs. Let me know if this solves your problem or at least gets you close. Thank you. And talk to you soon....Jay
