Question about RCA F27690BC 27" TV

1 Answer

Tuner I cannot get the TV to tune to any other channels. It is locked onto channel 49, which is not a clear picture and has a lot of interference. If I use a VCR as the tuner and go to an input I can get a picture. I think I got a power surge from my cable company and it fried my tuner. Can I replace the tuner myself? I am somewhat electronically inclined.

    Ok, see it now.  Thank you, but no, I think I will leave it to the Pro's. I was hoping it would only be a module. Thanks for your help.

RF codes are generally associated with older VCR's that used to output signals via the TV aerial system. It's when you used to tune the TV to the VCR channel. I think if you press a couple of numbers such as 4 and 9 on the remote it will then say RF-49. In which case if you have an old analogue tuner on your TV you could then tune it to channel 49 and see the VCR picture. Generally it's no longer used for the reason of digital TV, but also due to the fact you could not get a stereo sound with it and the picture wasn't as good as via a scart socket.

The remote doesn't effect the channels, I would say you have poor signal or interference from another device nearby.

Tv stays on one channel,no color or picture just ghost or outline, i have a Sharp lc46sb 54u

Check the settings to see if it is locked on channel 3 for external tuner source to have an input from a cable box ant in that needs 3 to function or from some other externally decoded signal like a vcr. Does the TV have a Digital tuner or the old analog tuner? If it's digital you can hook up a rabbit ear antenna with the UHF output on it & should be able to tune in some stations. If it's the old style then you will need a converter box to get it to receive any stations.
Fist check the settings to see if it has it set to lock on channel 3 for external tuner source.

Have new E370VL hooked up to Dish Network via coax. The picture jumps/blips? Connections are tight. Help.

This can happen when there is radio interference near the coaxial cables. Sometimes the interference is behind walls. The solution is to try a different combination of modulation and channel than what the DISH receiver is current set.

The DISH menu screen for this setting is Menu-6-1-5. With dual-tuner receivers, typically "TV 1 Out" is the TV that is connected in the same room as the receiver is located. "TV 2 Out" is the tuner that is fed to the remote TV via backfed coaxial signal.

All that needs to be done is to change the channel and mode going to the effected TV to something different. If your channel/mode is currently set to Air/60, try changing it to Cable/73. When you change the mode/channel in the DISH receiver, you need to set the remote TV to the same mode and channel.

Keep in mind that with some TV companies like VIZIO, they call their "Air" mode "Antenna". With VIZIO's the TV must be set on TV input and then go into the Menu to the Settings, Tuner Settings. Change mode type to match what you are trying on the DISH receiver, exit the VIZIO menu and manually enter the channel number.

Eventually with trial and error, you will find a mode/channel combination that isn't effected by your particular environmental interference.

Can you get to inputs on your tv ? I would use these inputs rather than channel 3 because you'll get a better picture using the inputs rather than the tuner. They are in the back Yellow for video and red and white for audio. But without the remote you can go into the menu to see if you can manuel program your channels but most of these sets you can't do that . might have your remote should you need one . Good luck

It's possible that V-chip is locked.. Go to the menu and see if the lock option is active... The backdoor password is 0-7-1-1 twice.. Entering it the first time, if it times out, will display "incorrect" just enter it again and it should ask you for a new password..
If that's not it let me know and we'll try a couple other things.

Tuning in to TV with wireless headphones

I need more info on this. What type of tuner and receiver? Is the tuner plugged into the headphone jack on the tv? If you have a tuner for tv that tunes in channels 2,3,5,12,25,60 etc that would be an older tuner that used the older NTSC standard. Tv stations now broadcast using ATSC, channel 4,1, 4.2 etc.
