And a bulb for my 42" Panasonic plasma is: $119.
Who told you that a lamp is needed for a plasma?

Plasmas don't use lamps of any kind.

I always notice smudging of the picture on Plasmas.
Plasmas can't smudge, any more than CRTs ever could.

Maybe those store experts don't know what they're talking about, any more than they know how to connect and set up a TV.

As always, misinformation is rampant.

But just to reinforce - there are no replaceable "lamps" on a plasma display.

In a 1920x1080 pixel display, there are 6,220,800 "cells" that create the red, green, and blue elements of the picture. Because they are active display elements they produce true black when turned off.

LCD/LED TVs are passthrough displays and always have at least a bit of light leakage through the display - hence the worse black levels. LED sets with "local dimming" can produce better black level than LCDs because the LED backlights in a dark portion of the display can be dimmed, reducing light leakage.

In most stores plasma TVs look darker than the super-bright LCD and LED TVs sitting next to them. So the plasmas often appear dull.

Take 'em home though, and in a natural setting, they are sooooo easy on the eyes. And LED sets, unless carefully adjusted to turn down the picture-on-steroids, are tiring.

A very good review of a recent Panasonic:

Test Report: Panasonic TC-P55VT50 3D Plasma HDTV | Sound and Vision Magazine

There is no LCD/LED that seriously competes with this TV.

Why... Jean71, of course!!
Sounded nuts to me so I did a search. I realize now that price was for a Panasonic HD Rear Projection TV.

Doh. My bad.

Nice try.



Kudos for (eventually ) educating yourself.

I'll probably buy a new TV sometime next year...maybe...so I've been doing some research.

In any case I found that Plasmas had received a bad wrap over the years. The only downsides with some models are 1. Glare, 2. Power Consumption. 3. They are a bit heavier.

Contrast ratio is usually much greater with a Plasma.

Color Reproduction is better with a most Plasmas.

Gaming/input lag is better with a Plasma.

General overall video quality is better.

Burn-in is a concern for any TV, with Plasmas, fortunately it is virtually a non-issue now.

LCD/LEDs are brighter, have lower power consumption, usually no glare and decent video quality. LED tend to have better contrast ratios (blacker blacks) than LCDs but generally lose out vs Plasma.

All in all Plasma seems to be the better deal, value-wise, for image quality.

For size, a cheap, "dumb", LCD might be best. For example you can get a 55 or 60 inch LCD for the price of a 47-50 inch Plasma.

I can't wait for the OLED TVs though!

Thanks for educating me on Plasmas.

Ive seen so many threads in forums about their "lamps" burning out.

I think your post is accurate. I will add that glare is less of a problem with plasmas than they used to be. Power consumption of plasma may be 2X that of LED, but it is still only $50/year even when used many hours a day.

You missed one thing that is very noticeable with LCD/LED TVs - the narrow viewing angle. Picture quality drops off dramatically for most such TVs for angles as small as 30 degrees.

I am anxious for affordable OLED.

The ones coming out next year are supposed to be under $10k. So we'll have options.
