Hi everyone, I just bought a used 32" older Sanyo tv. Anyway, we got it home and hooked it to Direct Tv receiver, put it on ch.3 but the picture is snowy and the sound has static, like its not tuned into the right channel. So I tried hooking it into the VCR alone, same picture. So at this point I thought maybe we bought a lemon, however when I put it on video mode (blue screen) its clear. Besides, I would think if it were the tv either the sound OR picture would be going out, but not BOTH at once. I keep thinking I don't have it on the right channel but I've gone thru all the channels. It goes from 01-99 & 117 channels. Any advice?
Well after playing around with the tv some more, I decided the problem was probably the cable jack, and tried running the video in/out cables thru the VCR to get around this, which I read generally works but in this case nothing. I had tried the tv on various settings, anytime I put the tv in "video" mode I'd get a blue screen and nothing else. Anyway I found a switch in the back of the Direct Tv box for ch. 3 & 4 settings. So I flipped it but still got a snowy picture, only this time it was on ch 4 instead of ch 3. By sheer accident I put the tv back in video mode while I had the satilites setting to ch 4, and the picture came up crystal clear. Since I didn't mess with it further, I'm not sure if it was the channel selector or the fact that hooked the tv up via the video cables, but whatever it was it did the trick.
I just KNEW this could not be a broken tv despite the fact that everhwere I read online suggested it was. I knew pictures can go out, or sound can go out....but to have BOTH go out didn't make sense to me. Anyway, glad its working! :)

I'm not sure about the model number of your TV, as here it is marked as both "27MS343S and 32MF338B/F7". Anyway I gies this solution as for the first denoted.
Insert antena to the antena socket at the back side of your TV marked as 75Ohms antena input.
 Press "Menu" button on the remote control handset to display menu on screen.
 Press "Vol+ or Vol--" button repetedly to hilight "TUN" [Tuner].
 Press "Ch+ or Ch--" button to hilight 'AUTOPROGRAM"
 Press "Vol+" to programming tv channels.
Tv will tune and store channels transmitted channels at that time, through entire bands, and will display the first channel receved after tuning process completed. It may take some minutes. You have to wait it to complete. After displaying the first channel, you can select your favourite channel Using CH+ or CH--" buttons. Ok.
This may be due to the possiblity that the you are on the wrong input source, If you watch HD Channels then the input source would either be componet or HDMI input. Try changing the input source of the television with the TV's remote until you see the Channels again. IF you are not watching HDTV then the television is on the wrong reception channel for the Direct TV's box. Try channel 4 or 3 or even 73.
The only work around you have without a remote is sloppy. If you are patient, give it a go: connect the box to the TV (cable/ant input), turn on the direct TV box, using the TV button panel (here comes the sloppy) fumble your way to the auto-program menu, start auto program. When the auto-program is done, you will have just CH 3 memorized, so the CH -/+ button will only go to that channel. Worst part will be figuring out the buttons on the TV... it can be frustrating. It may take a few tries, that's why I call it sloppy. I hope this was useful, best wishes.
Hit the Menu button on the TV. 2. 'INPUT SECRET No.' should appear. 3. Press and hold both VOL (+) and CH DOWN (9) on the TV set simultaneously until the message 'INPUT SECRET No.' disappears. 4. The vchip settings should be disabled now and the Parental controls menu should be presented, 'disable' Status if need be.
bring the tv out to the main tv and hook it up to that connection to determine if it's the TV or the connection. Or try hooking up a VCR to the tv while the TV is set to CH 3. Do you get a blank picture or a snowy Picture?
