May be they have concluded that there is not much to research further and continue to use the present technology and plant for few years and then discontinue slowly. The same engineers can be used for other future technology research purpose.

To a large extent I would say it is because all the research into the neo-plasma panels still did not bring down the power consumption to acceptable levels.
The plasma panels consume nearly three times as much power as an equivalent LED backlit LCD panel!

I doubt it is 3 times. I'm told it is more like one and a half time.

OK, let's see Panasonic's own specs for their top models in 42 inches size:

LCD/LED: 107 Watts: http://www.panasonic.co.in/wps/porta...dtv/thl42dt50d

Plasma: 300 Watts: http://www.panasonic.co.in/wps/porta...atv/thp42gt50d

That looks far closer to three times than 1 times.

And samsung has a 43 inch plasma that consumes just 115 W.

I think it has more to do with their profit margins, plasma TV's below 46" are definitely cheaper than their LCD and LED cousins, remember how projection TV's were phased out with very high dropping of prices. I still argue Plasma TV's can only crisp pictures even for a SD content.

Which model?
Is it full HD?
The more the 'pixels' the more the number of 'cells' and hence higher the power consumption.

Power consumption in LED LCDs is almost constant where as in Plasmas is variable and it depends on content (darker scenes consume less power than lets say a full white screen with full brightness). So its not that 300W will be consumed all the time.

I was under the impression that modern plasmas consume less power than they once did and they heat up less. In any caes, since I'm inching towards Samsung plasma ( Pana dealer in Vizag is clueless about their model line-up ), I will drop in at store and do power consumption comparison of 51" LED versus 51" plasma.

Yes you're right. It's not a full HD one but is 720p. Can't remember the model number though.

But i guess we think a lot when it come to power consumption. We all have 2, 3 or 5 star acs in our home. If one wants to really save on electricity. One should invest in an inverter ac. You'll get substantial savings. I for one am paying 4k per month instead of 8k ever since i replaced 3 of my non inverter acs with inverter acs. But make sure one gets the appropriate tonnage.

Viera plasma tv of 50 inch panel size consumes 146watts of power on an average. On the other side, smart viera 50inch LED consumes 58watts of power. So that still makes the plasma nearly consume nearly three times more power. However, 146 watts is not such a power hungry device IMO compared to the 300 watt plasma mentioned.

On a side note, my sony bravia consumes 90 watts of power on an average for a 40inch panel compared to 58w for a 50 inch panel. Wonder why!

The 300W quoted in specifications is maximum consumption with an absolutely white screen at 100% brightness level. Under normal viewing this figure is closer to 40~60% of maximum consumption so both the figures i.e. 300 W for max and 146 odd W for normal viewing are valid.

It is a Sony. Commands a premium in price as well as in power consumption

Now guys after long last I have managed to find a dealer with a 'peti' packed unused 42GT50 panel, he has offered the same to me @89K MRP is 1,19K What I need to know is the price of this panel that was prevalent around Diwali last year. In case any one here has bought this panel around that time or maybe around the turn of the year please advise the price you paid for the same. This might be my last chance to get this panel as this size is discontinued in the 60 series, need to close this in a day or so.

I remember you had mentioned 82K for this in Diwali time frame. I had tried getting this for 84K, but then moved over to buying a 50 incher instead.

I would say, 82-84K would be good for this TV.

Somehow I have heard of more people with GT50 having issues compared to ST50. I don't want to deter you from going ahead, but Modern Electronics (some seller on Infibeam) is based out of Delhi and might have 42ST50 with them perhaps. Getting their contact details will be difficult.

Edit: In UK, they will get ST60 and GT60 in 42 inches, so there is some hope for India too.

...
And how is the power rating measured for LCD/LED TVs?
Full white screen or full black?

Anyway, this site will help clear many questions: http://www.rtings.com/info/lcd-vs-le...ectricity-cost

Yes I recall 82~84 as I was offered the same but the panel never made an actual appearance at the shop. I was left with a feeling that they were able to sell elsewhere at better price levels and that's the reason I wanted to know what price people actually bought this panel for.

I want to get te thx setting option and the same is not there in the ST. 42" in the 60 series is good news but then unless these are available in the gulf not of much use to us, eh! BTW any idea on what sort of issues are being faced with the GT?

Thank you for the link sirjee, does confirm that plasma's max consumption is with all gas particles fully excited leading to the white/bright screen. Always believed that lcd/led max power consumption measurement would be with all of the lights simply switched on white screen or otherwise, bulbs/diodes after all. Nice curve ball though!
