If so...see the thread here titled " ON/OFF ISSUES" and also see posts over at Consumer Affairs:
Thousands of us are having the same problems with no response from Samsung.
We have a Samsung 42" plasma that is 2.4 yrs old - according to the repair places we have taken it the video board is toast. Approx cost to fix is quoted at $900!
I called Samsung only to get the "well its out of warranty so we can't help you"
What happened to Samsung's Vision "In everything we do, we strive to help people live better lives."
They are telling me that a plasma tv 2.4yrs old with a garbage video board is my problem and they aren't willing to help me find a solution that doesnt cost me $900.
Nice to see they stand behind their products and customers.
