I received this set from a friend, to replace a set with a broken coax connection. My antenna brought in my local channels on the old television but will not work on this set. I changed the input on the menu to UHF/VHF and when I have the antenna screwed in I can change the channels and the picture doesn't seem to be any different from one page to the next. Help!!

Re: Antenna on RCA F27615
If this set has Guide Plus in the menus then set it up. Choose ant or cable, in menus, and No for cable box and no for DVD and no for vcr and finish. If you choose yes for a cable box then it locks the channel to 3 to match your cable box.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You must have a UHF / VHF antenna connected to the antenna input of the TV to scan for digital channels. Most new TV's have a threaded, round 75 ohm coax cable connection for this - but yours might even have connection consisting of 2 small screws to connect a 300 ohm twin lead antenna cable instead. Use which ever yours has.
If you are using this input for the input of a cable TV "set top box" (STB), satellite STB, or similar, you will likely only find a single analog channel (Ch3 or Ch4) after a scan as the scan will only find the output of the STB - which is usually on Ch3 or Ch4 - and not be able to scan the STB channels.
Additionally, the antenna input of the TV will only provide a standard definition picture if connected via coax cable from the STB. It will only provide a high definition picture if connected to a UHF / VHF antenna anda broadcaster is close enough for its signal to be received by the antenna. The way to obtain the best possible picture (high definition) when using an STB for tuning channels is to use an HDMI cable between the STB and TV. An HDMI cable will provide the very best picture and audio signals from the STB to the TV; all over a single cable and is the recommended practice.
There may be an issue with the coax, antenna, connections, settings or a combination of them all.
Set the radio to AM, a channel of your choice, volume to just under 1/2 way, squelch to off or fully CCW. Make there is no plug in the ext speaker jack. If there is still no sound, try connecting an external speaker and try again.
Carefully check all connections for tightness and inspect the coax cable for evidence of being crushed, pinched, cut and jacket damage that could allow water to enter. Replace the coax cable if any of the mentioned problems are found.
Inspect the point that the antenna is connected to the mount / coax cable. It is not unusual for this area to become oxidized due to exposure to weather. Thoroughly clean or replace parts that can not be cleaned up.
Check the antenna for damage. If "higher than rated power" has been introduced to the antenna, it has likely failed, and will require replacement. Since CB is limited to 4W AM and 12W SSB, most antennas are rated for 25W or less.
You should obtain and connect an SWR meter with a short length of coax cable between the radio and the antenna. The meter should be rated for the frequency range of the transmitter - in this case, HF or 27Mhz (11 meters). Tune the antenna for lowest SWR over the range of frequencies by physically lengthening or shortening the whip in the base in 1/8" increments.
If you are trying to connect a VCR to your television and still have Directv, this is the way to do it. Disconnect your Directv receiver from your television, Then connect the VCR to the television either through coax or RCA cables. If using the coax cable connect the out to tv on the VCR to the television. If using RCA cables connect the RCA OUT to the television AV1 connection. Once that is done, connect tha Directv receiver to the VCR using either coax or RCA cables. the Directv receiver only has RCA outputs so, if using RCA cables connect to VCR in. Remember that in order to see the Directv the VCR needs to remain on and it must be on the channel line in. If using coax cable connect to the VCR where it says in from antenna. Remember that if using this method your VRC does not have th remain on to view Direct. If you're trying to record Directv, then your VCR need to be on the same channel as the Directv output channel either channel 3 or 4. If trying to record Directv using RCA connections the VCR needs to be on the AV settings. If you have any futher questions please feel free to call me at (361)510-0339
if you have the coax cable connections correctly connected , coax out to tv from box and antenna hooked to antenna in on the box then you may have to connect the RCA jacks, yellow = video , red = right audio , white = left or mono audio
because on these boxes you can choose in the menu to have the coax ( channel 3 or 4 ) as the output or the rca jacks ( line out )as the output . so the menu may be set for the rca jack connections untill you change it in the menu
I recall problems grounding the antenna on those kw's. May want to try a no ground antenna. Also the stock coax that comes with the truck sometimes gets broken or pinched. Go to a good shop, replace the cheap coax and grount the antennas.
Are you using a cable box or is your input through the coax cable or antenna? If you are using a cable box with RCA connections make sure the Red and Black cables are securely plugged in both the cable box and the TV. Check to see if your TV has sound by going to the antenna input and select any channel and crank up the volume. If you don't hear anything you'll probably need a new TV.
