Samsung PND7000 - red LED light blinking when turning on but TV still works?

Can anyone tell me if they know what would cause the red LED light to start blinking when I turn on the TV set? This had never happened before but I noticed the TV started to do it earlier tonight and now appears to be doing it whenever my TV is turned on?

Like I said, the TV is still working but I'm trying to figure out if my TV is about to crap out on me. I just had the panel and main board replaced ~2-3 weeks ago.

EDIT: LED light blinks 5 times if it makes any difference - I'm 90% sure it didn't do this in the past but maybe I'm going crazy

Would someone with a Samsung D series plasma mind telling me if their TV does the same thing?

Great, thanks a ton for taking the time to respond. For some reason I never noticed it and I had read so many things that always seemed to indicate that blinking LED was a signal of something bad.

Thanks again!
