It may very well be the tuner. If it has another means of connecting to the tv try composite or component cable. If that isn't possible try replacing the coax from the wall plate to tuner and from tuner to tv. This is if you have a cable box also called an STB in your home. If you do not have an STB try changing the coax from wall plate to tv. You may even want to replace the barrel on the wallplate as well. If the cable runs through the VCR disconnect it and run it straight to the tv and this will determine if the problem is in the VCR.
Hope this helps you out.

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.

Scheduled a timer recording of a program on a DVD+R and when I went to play it back all I got on the screen was noise and snow. I now realize that I used the wrong disc (should have used only DVD-R). ...


Hi,During timer recording adjustment you must have selected what ever you want to record..i.e: Tuner Channel , or ,Video1 input ,or Video 2 input etc..This problem is related with Source selection but not with - + type Disc..wrong disc will refuse to record at the beginning..

The noise and snow shows that your recorder was Recorded an unadjusted RF channel..thus no TV signal was available during recording ..
I assume that your DVD recorder has built in TV tuner in...To correct the problem,first you make an automatic Ch set up ,search the available channels either on the Cable (if you have ) or RF local channels thru Arial Antenna..
than you try to record again by carefully selecting ..you will record TV RF channels successfully. Or you can attach another video source to your Recorder thru the RCA cables on the back panel and by selecting the respective SOURCE in accordance withe cabling you have made than you will record the AV signals available on your Receiver..
If you need more help pls let me know for further advise.

Bill, your set has a bad tuner, only fix for that is to R & R the tuner, 2nd option would be to use your vcrs tuner input and then RCA out cables from vct to input on back of tv, If you have never done this re-post and I`ll walk you through it, let me know, BMW Rider
