I am new to the forums and have a question. My folks have a Zenith Inteq IQC50H94W that they said has stopped working, no sound or picture. I looked at it today and when I turned it on it had picture and sound. There was no signal going to it so it was static and white noise, but it came on. I then powered it off and hooked a DVD player to it and turned it back on. This time nothing came up, no picture or sound. I turned it on and off a few times and there was still nothing. The light on the front was red but nothing happened. So I wanted to know if anybody knew what I could try or what is wrong with it. Thanks.
