Guys , just sharing my experience here on LCD TV
if you can affort go for LCD. Plasma may have seprior performance in certain aspects but reliability can be an issue. The burn-in problem is a real issue.
TV is something you use everyday, atleast 4 hours / day. It has to be reliable . This is my presonal preference I always buy Jap, brand for TV, Washing Machine and Fridge.
LCDs used to suffer dark area noise problem and slow response time. But this has been dramatically improved in the recent years.
SHARP is atleats 3 years ahead in LCD TV technology and has really good panels. Well designed and well tested TVs.
Samsung is value for money. I've no idea on it;s reliability. Good performance and good
looking.
I stay away from Philips ( due to some past experience - some of thier electrical goods has very poor reliability ).
Sony makes excellent CRT TV , real good video processing. Even today I'm impressed with our 29" bought 10 years ago. However they are new kid in the LCD town. We tested a model 3 years ago and performance not upto competition. I'm not sure where are they today.
Dont simply believe the marketing hypes and specs alone. If you planned to use one for watching HD contents, then get the shop to test it with a 1080i source. Make sure the TV has HDMI input. A TV that accepts HD input and a TV that has HD panels are differnt.
Ask what is the panel resolution. A true HD panel should have 1920x1080 pixels.
But it's not necessary to have a true HD panel to view HD content. A WXGA (1280×720 ) panel will perform very well for sizes upto 37" ( my experience ).
