We have a Samsung TXT3093WHX/XAA.
We moved recently and since that time, it is hit or miss-mostly miss, whether most of the inputs are going to work. I'd say it was a result of how the movers may have handled the TV, except that I moved it myself and there was no jarring or bumps that occured.HDMI
works great through our TimeWarner cable box - No problems.
Any other input: Composite(AV1 or AV2), S-Video, Ant produces all produce a streaked snowy bar across the middle of the screen and the TV must be powered off, the video input removed and the TV turned back on inorder to bring the normal picture back.
We have an analog 3-way switch that allows us to switch between DVD/Video player, XBOX or Wii. This had always been connected to the AV1 composite input and had worked fine.
I've tried changing the Composite cable(s) with a new one. No difference.
I've tried connecting the devices directly to the TV via various inputs/cables. No difference.
I've tried direct S-Video. No difference.
I've tried direct coax into Ant. No difference.
The audio is clear in the background, however as soon as the video is connected the screen goes to the stretched, streaked, snowy picture. Sometimes it may take a few moments after the input is made, but generally it is immediate.
Thanks for any feedback or ideas.
