Q. College friends are saying to change my LCD and instead of that, I should buy LED. What can be the solution dear?
A. Get plasma, it destroys LED/LCD in picture quality easily and are cheaper. You can get a GT25 or ST30 3d HD panasonic plasma at 42 inches for 1000 bucks and make your friends jealous as hell.
Look at Cnet's reviews Google best 3DTV or HDTV of 2011 and the top 5 are plasma's. Maybe 1 LED is in 6th place but its 3 grand.

If I only have antenna TV, what TV is best to buy?
Q. I current have a tube type TV. In Canada we get digital TV signals from the States. It seems that the signals from Canada are still analog.
Are the digital signals transmitted at 1080 or 720, 120hz or 60hz?
What TV would be best without over spending?
Thanks.

All broadcasts are in 60 hz. The whole business of 120 & 240 hz has to do with the internal functioning of the TV. Basically early LCD TVs were really bad at smearing of high speed action like sports. The 120 & 240 hz are electronic tricks to make fast action look as good on LCD TVs as it is on plasma TVs.
The digital broadcasts are a mixture of 1080i, 720p, and 480i resolution. The HDTVs take care of converting these signals to match the TV's display.
As far as picking the minimum resolution (720p vs 1080p) and refresh rate ( 60 vs 120 vs 240 hz),
consider what you are going to use the HDTV for.
Screen size & distance from the screen that you sit? Start by figuring out what size screen you want.
Big screen size, sports with fast action, or HD video games point to the need for higher resolution and hz ratings.
Many people pay extra for ratings when they can't actually see the difference on the screen. If you are watching ordinary programing on a 32" screen, there is no point in paying extra for 1080p & 120 hz.
On the other hand, if you are a sports fanatic watching a 50" screen, you will want the higher resolution and hz rating.
There are already digital broadcasts in Canada; the Aug 2011 date is when most of the old analog broadcasts will be shut off. The US and Canada use the same TV broadcast standards, so if you can scrounge a US DTV converter box to try out, it should work.
Three important things about digital antenna reception:
1. Many people find that they need a better antenna for digital reception. What constitutes a "better antenna" depends on your location. Buzz words like "HD" or "digital" on an antenna box are meaningless as far as picking a TV antenna. (In North America, all TV antennas, even 30 year old ones, are "digital".)
2. How good an ATSC tuner the TV has is important. But it is very hard to find information about which models have better tuners. The first link below is to a discussion about this. Since most people in the US have satellite or cable, manufacturers sometime cut corners on OTA tuners.
3. If you will have to adjust your antenna to pick up stations in different directions, make sure the TV's tuner has the capability to add channels without deleting old ones. There is at least one brand that doesn't have this option. Unlike analog TV tuners, digital OTA tuners have to find stations by either "scanning" or manually adding adding stations. It's a problem if your TV wipes the old channel information when you point the antenna to another city to pick up more stations!
