Red Horizontal Lines with LCD TV	Can't Post

Hi,
I have a 42" Philips TV that has 7 red horizontal lines going across the screen. I called Philips and they were no help. Has anyone experienced something similar? Is my TV bad? Please let me know.
Thanks,
swb1

Hard to do any research without appropriate information. Unimpressed

Well the other option was:
It's time to play another round of the wildly popular game show "Let's All Try To Guess The Model Number." Wink

By this point in time how many "different model" 42" LCD sets has Philips made?

So all you needed was the model #, which you have now?

Research so far:
It's approximately a 2006 vintage set that was most likely purchased at Costco.
Without doing further research, all I CAN say is that one or more boards/modules are defective.
Remember most flat panel sets will last past the end of their warranty (average: 90 days to 2 years), but not by a Whole lot (3 to 7 years on average before first failure).

Let me do some more research and if I find anything I'll post again.

Wasn't aware they used DMD boards in Plasma sets?
