It quit coming on. I unplugged it a minute plugged it back in then it turned on and came on for 5-15 seconds then went off again. I repeated this several times several ways with the same result. We have been hooked up with U-verse 6-7 months, and dish before that . We had a similar problem happen 6 months after we first bought the TV, (6-06) receipt says defect code C202-3042 and replaced PC board. Does that sound like the same problem? What does that mean, and how much does it cost to replace?
