2006 Samsung SP-S4243 plasma tv smoke

[pac.attack76]

So I picked this tv up at the curb and brought home. It had been rained on at least once but was 48 hours before I picked up. Decided on plugging it in which I usually don't do for a few days in case their damp but this time, I got impatient and wanted to see what it would do. I plugged in and it played a tune and the blue led around the power button came on. 3-4 seconds after, I noticed smoke coming from the top right in back. I immediately unplugged figuring something might be damp and waited till next day. Figuring I may have blown something and caused it not to do anything at all, I tried again and it still played the sound and blue led but within 2 seconds, I seen smoke again and unplugged. Any idea what is going on. Wondering if I did this or maybe it was already doing.
