Cant change channels

try to unplug it and a cable or sat box if used from power for a while to see if a reboot will help---also the fact you cannot change channel etc means the set experienced some kind of glitch.

Stayingh on blue screen with video 1. Do not have remote

have you try the display button on the remote/or input button till you back to the picture
hope that will help
have a nice days

Need s to be replaced the main board.

Try some new batteries in the remote, or, just roll the batteries in the holder.

Look for a button on the remote or front of the set that is labeled input (could be tv/video) this switches between video inputs and the tuner.

You need to change the source (original remote) or the input (univeral remote). It needs to be in TV mode - not video.

I CANT GET THE AUTO SELECT FOR CHANNEL TO SELECT

If you have the original remote, hit video, source, or input button, if it dont have them, then try to change the tv to channel 00 (zero or zerozero), if not then the channels might have to scroll to it, from channel 02 down to make it loop, if it goes to the next highest channel, then you need a remote. It may be set in the menu options to have the video source not saved to your list of saved channels. when you scan the channels, the tv might not look for the A/V source (audio / video), maybe just the RF source. The 3 DVD RCA wires are 1 video and 2 stereo, one stereo for left and one stereo for right. The TV has only 2 , 1 for video and 1 for mono 1 channel sound. This wouldnt have anything to do with why you cant use the DVD player. but try that with the original remote (or a universal remote that is set to your tv set that has either video, input, source or something similar. It is what tells the tv to change from the cable source (RF) and the AV source (the Red White and Yellow plugs, in your TV's case, 2 plugs, one yellow and the other either red or white or something). Dont really know how to explain it much more but hope it helps.

if you have a sky remote or know someone who does you could try programming it by using one of these codes, try them all one at a time
