I getting sound but no video, i can see the menu ect...

in the menu you need to set the audio sauce,, analog . digital ect

You would have to disable or disconnect front keyboard to know if keyboard is problem or something else

What type of antenna are you using? Or what is your source for accessing channels? (i.e. - are you connecting to a cable tv service box or are you using a receiver ect.) Make sure that your source is connected to the input method that you are currently using on the tv.

There are many input methods to choose from in the settings of the tv. They are generally called antenna 1, antenna 2, cable, aux, hdmi - and a few other names. There should be a button on your remote to change them. The function is usually called "source" or "input". Press that button to change the input method until you get a picture on the tv or pick up some sort of reception. when you have the tv set on the same method of input that your antenna source is connected to, you will get channel reception or some sort of picture. Thats when you use the menu functions to auto find channels for you and let it go through its checking scan to report how many it has picked up.

If its running the scan for channels and not locating any stations, and the picture is either scrambled with the white noise sound tv's make when off channel or if its just single color screen without any sound - then you know the antenna input method you have chosen on the back of the tv is not the current method set in the settings under the menu key.

Most of the time the inputs are labeled on the back. If you look under the cable antenna connection, it should say "cable" somewhere in small print - or "antenna 1 input", antenna 2 ect. Look on the back of the tv. If you are using RCA jacks that are labeled right and left for sound and a third connector for video ect, look for the name of the input method of those three connections on the back of the tv. It should be marked as input - aux 1 ect. Then just change the source chosen in the tv to match it and have it auto program your channels.

Try resetting the TV to the default settings (Menu > Setup (Options) > Memory Recall (Restore Default), select Yes and then Enter. Exit the menu to save.) Then rescan all channels. The Setup or Options menu icon looks like a wrench and hammer forming an X.

My Viewsonic TV uses the commands in the parantheses but the current manual for the model gives new command names. The above commands worked to solve the problem for me. (In my case, one digital subchannel had video but no audio but the sister subchannel had audio but no video.)

I hope this helps.

You can get the installation guide for a Zenith H27H38DT free at the following location. Look on page 36 to go into the VIDEO MENU and set PICTURE PREF to PRESET. That should restore the factory settings, so try that first. If you go into the actual Installer Menu on page 41, proceed with caution.

We put the tv on channel 3 then ran coax cable from the direct tv box to the tv and the display disappeared. The s-video cable was run from video 1 on the cable box to the video 1 on the tv. So he left the s-video there but by putting the tv on channel 3 and running the coax it fixed the problem.
