Video warps on edges then cuts out to black, then fades back in
Hello experts! Well, my Samsung TXM3096WHF 30" TV has been exhibiting some odd behavior for the last 3 days or so. The video will kind of "warp" or wiggle on the edges of the pic, then it will cut out to either full black, or just darken then head to the center of the screen, sometimes looking like a double image. It will then recover anywhere from 2-10 seconds later & pop back into a normal pic. Note: it almost makes the same sound as when the TV goes off & comes on...kind of a "static" pop as the pic goes out and comes in. This behavior happens about every 30 seconds - 5 minutes or so. Audio is still fine & playback on Tivo or normal TV is fine.
Here's what I've done: I've checked the cable connection to the back - it's tight. I've checked the cable connection from the TV to the Tivo box - tight. I've checked the other end of the cable connection to the router - tight.
It should be noted that I've never had any "tuneup" done on this TV and it's about 5.5 years old.
While typing this note, the video has popped out about 5 times. :(

I would say you have a power supply or deflection system defect. This would need a technician to diagnose the problem as it will require some tests to determine where the problem is originating. For example, a main power supply defect could cause reduced supply voltage which would affect both vertical and horizontal deflection.
how long have you had this set. it sounds like you are having a power board problem most likely the board is dead you will have to take it to your local tv repair shop or if you are good at stuff like that you could open it up and see if their is any blown caps or burnt spots on the board
In this model the horizontal drive coil vibrates and makes a high pitch squeal. Most times it is intermitent. Touching on the coil with something (non electrical, like wood) will make it stop or change it's pitch.
The fix my shop uses:
It's not to technical, but, we put fingernail polish around the coil. It's a remedy I've used for decades and has always worked. Some shops use a hot glue gun.
With the back open you can hear the coil to locate it. When fixing the problem have the set unplugged.
When a technician is working on a television while it's plugged in. He uses only one hand and stays away from the high voltage.
