Interest in plasmas and was wondering if there could burn on issues with this technology. I thought it might be different from other displays since its gas, any help is appreciated. Thanks.

Yes. LCD and DLP basically do not.

Plasma can exhibit "burn in" just like a CRT, since it uses phosphors just like a CRT. The only difference from an operational standpoint is that plasma sets energize the phosphor by ionizing the gas (in a manner similar to a fluorescent light), whereas a CRT uses an electron beam to achieve a similar effect. But phosphor is phosphor, and it has a finite lifespan.

Semi-OT but related - ever noticed how new fluorescent tubes are brighter than old ones? It's the same thing as with a TV--the phosphor coating wears and gets dimmer with use.

Yes, plasma's are perhaps the most succeptable to burn in of any modern display technology.
