plasma? LED? LCD? i have an almost 3 year old samsung plasma that overall, i've loved it. i've been happy overall with samsung products for laundry, cooking and fridge. and oh yea, tv. however. recently a thin purple line has formed on my tv only seen under the right conditions. usually a bright blue screen behind it. from what i can find, this is the kiss of death. the plasma (insert correct words here) are dying and the tv is going to follow it to an early grave. i had no idea when i got it, or even where. but i do "pack rat" things in my garage and the box it was shipped in was still there. with packing receipt. i got it in 2010 w/a 3 year "square trade" warranty. being 2013 and in the later half made it interesting but as luck would have it, late november is when the warranty ends. i paid almost $2k for it almost 3 years ago and from what i can tell, i get the almost $2k back to replace it. so the question is, i do tend to leave my tv on a lot which i've found plasma doesn't care for. i don't give a hippies flip flop about 3d. i do care about built in wi-fi and getting rid of the ghosting on the pics of many HD TV's. now i'm looking for suggestions on why one technology over the other. again, i tend to leave the tv on, don't care about 3d, do want internet connectivity, (smart tv) and all for around $1500 give or take. brands i tend to prefer are sony, LG and samsung. any suggestions?
