My Samsung TX-P3071WH recently started doing something very strange. I turn the TV on, and after about 10-15 seconds it turns itself off. Then, 10-15 seconds later it turns itself back on. Then, 10-15 seconds later it turns itself off again and continues this cycle until I physically unplug the TV. I'm hoping that someone may have an idea of what I can do to repair this thing. I use to repair WYSE terminal monitors so I have a basic understanding of how TVs work. Any information or help would be great! Thanks in advance.

Sounds like peanut butter/jelly jammed sticky buttons.

No, it doesn't seem to be sticky buttons. I've pulled the batteries from the remote, and the power button on the TV isn't sticky at all.

These Dynaflat tvs are supper hard on caps. You have a power supply problem of some kind.

open it up and discharge the tube before you do anything. look for blown or poping cap or burnt out transistors on the mainboard. sometimes the extreme heat can cause dry joints on circuit boards also...just reflow the joints.

hope this helps
