I recently bought Pana 42X20D.... caz I was on a budget *period*. Having said that there are following advantages of Plasma:
- motion blur on LCD is more pronounced, plasma's due to their fast response time dont suffer from the same (very important in Indian context given our SD signals)
- Darker blacks
Negatives
- Image Retention
- Burn-In (permanent damage) possible no matter what the manfacturers say
- Shorter life
- Heavier
- More power consumption
- Cant work at high altitude
As you read above, the negatives outweight the positives and therefore the market has moved from Plasma's to LCD->LED's over the years. The numbers say it all, in 2010 Plasma's sold 2 milion IIRC as opposed to 20 million LCDs.
Now having said all that Pana does offer great picture quality for all its cons and is covered by 3 years warranty. If you have 10-15k more to spare go for LCD else I would recommend Plasma.
If I had a choice between an expensive Plasma or LED TV, budget no bar, than I would have gone for LED/LCD. Thats the honest answer, no matter what anyone says on this forum.
have you yourself faced any of the problems that you have mentioned and have they been repaired?
