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.

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

Tuner will not pick up cable box on channel 3, front and rear AV

In order for the TV to work with the cable box by using a piece of coax and tuning the TV to channel 3, you must make sure the TV is in "Cable" mode on the tuner and not "AIR or Antenna" the frequency maps are different between these types of service and channel 3 cable will not be the same as channel 3 on Air or UHF/VHF.

Often there is an auto program feature on TV's that will "scan" for all available channels, and this should select the proper input type.

Hope this helps!

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.

Television stays on one channel

You likely have bad solder connections in the tuner.
