Question about RCA F27450 27" TV

TV won't change channel

After a friend touched it (don't know what he did), TV stays on 1 channel (Global). It is connected to cable but, whatever channel the tv is tuned to, it is always the same channel appearing on screen. Remote control doesn't work anymore (except for sound) and controls on TV itself seem to work, but without effect. Could someone help ? Thanks, Michel P.S. Is there a way to find the user manual ?

My tv sanyo cm21kf81A, chassis number FC3-G221 has snow noise on all tv channels, but AV1 and AV2 play good sound

First check cable wire or whatever is connected to set for channels--the leads are connected and wiggle them with set on to see if it clears up--could be a connection where cable wire is connected at end--loose connection there etc.

If tuner is bad causing this and you use a box for signal--most have rear audio/video outputs you can connect to a unused video/audio input on rear of set---bypass the tuner in the set and operate set that way changing channels on box instead of set.

let me know if you have questions or have more information.

Hi, I bought this tv at thrift shop last week. No instruction manual available. I got cable from Time Warner. Got the cable signal and got tv working. 3 days later no cable. I don't know how to...

If using a cable box then you want to set the TV to channel 3 or 4 as the cable box will output to one of those. If no cable box then its possible the TV's tuner is bad or your cable company only transmits in digital form requiring a cable box since this TV only has an analog tuner

TV Stuck on 1 channel

We would be happy to help get that fixed right away. The first thing we want to ensure is that all connected equipment is on. We want to then check what type of cable was used to connect the TV to the receiver. If you are using a Coax Cable to connect the receiver to TV1, check the receiver's back panel for the output name. If your receiver has a "TV CH 3/4 out": Tune TV to channel 3 or channel 4, back if it is labeled "Home Distribution": Tune TV to channel 62 or 75. If using non-Coax (RCA, Component, or HDMI) to connect receiver to TV1, cycle through the inputs until picture appears; Most TVs have a "TV/Video", "Input", or "Source" button. If we are still not getting a picture then unplug receiver for 10 seconds then plug it back in, this will reset the receiver, then try cycling the inputs again.

We hope these steps resolve the issue. We want to thank you for being a valued DISH Network customer!

My toshiba tv only goes up to channel 12, when it reaches channel 12 it starts back at channel 1.

You will need to re-scan the channels, i don 't know where it is on the menu of this set. If you are on cable, you need to make sure your tv is set to cable tuning, or you cannot get channels past channel 13. Same is true for antenna if you are on antenna make sure you are set for this.

Phillips dvdplayervideorecorder connect w/zinwell converter box

First off get the TV on the right channel. It will either be ch3 or ch4. If you are using a cable box the dvd/vcr combo will have to be on ch3 or ch4 as well. OK, Make sure the input connector on the combo is hooked to the output connector of the cable box and the output connector of the combo is hooked to the input connector of the tv. Deal with one part at a time. First hook the combo to the tv and get the tv on the right channel (ch3 or ch4) so that you can see a pre-recorded dvd or video play. Then you will know what channel the tv is supposed to be on. When you find it don't bother the tv channel any more. Stop the dvd or video and hook up the cable box and turn on the cable box and set the box to a known good channel. Now put the combo on ch3 or ch4 with the combo's channel selector buttons until you see the cable box playing on the tv (remember you already set up the tv channel). Change channels on the box but don't bother the channels on the tv or combo anymore. You can put the box on whatever channel you want. The box will be your channel selector. I certainly hope that this helps. I know it can be confusing but don't give up. Just remember that the tv and combo have to always be on ch3 or ch4 (which ever one you found before). Good luck and thanks.

Dvd player

Hi, where you plug the dvd cables into the tv determines where the picture will be seen; Example, if you plug the dvd players yellow, red & white cable into the tv`s "input 1" then you go to the tv`s "input" or "tv/video" button and push those buttons to get "input 1" to come up on the screen and you`ll see the picture and hear the audio, it`s kinda like a file folder in your computer, you`ve got to find the file then open it to see the contents. If your tv is on channel 3 or 5 or whatever you won`t see the picture because the picture is in video not a tv channel

Intermittent blue circle on display

Yes this is certaintly a strange one, as you say not all channels have it?? Ok lets try to narrow it down a bit. Do you have cable or satallite ? Is the cable or sat. connectected through the video inputs or does your TV have to be on a certain channel? ok and you say its not there when your watching a dvd? The only answer here is that you have a problem with your cable or the sat system, as the channel stays the same on whatever channel your watching while on the cable, so if you have a problem with some and not others , Your TV dosent know the differance from one channel or another, as its always on the same channel on the tv . So what does this tell you?? Theres a problem with the sat or cable reciver! Cant be the TV as I said the TV doent know the differance from one channel to another as it always stays on the same channel. Sounds like you need toi have cable come in to check the impedence and signal streinth.. now if your sying thast the tvs on locals and some do it and others dont ?? then theres outside interference causeing this problem? Good luck
