hi guy's ...
i have a question to those who have purchased panny recently..
my 50 incher suddenly cracked all by itself in spider web form from inside and Panasonic is saying will not be treated under warranty for someone has hit it very hard thus it cracked from inside , thus complete TV and 65K is wasted
researched a little bit and found it is due to the thermal expansion and shrinkage of the glass and lot of people suffer form the same problem and lost there complete investment and peace..
what should i do??? guys pls suggest way out..
though i have sent mail to the panasonic help line and south india service head.
here is the whole letter for your ref" which i sent to the panasonic india h/o and south india

Dear
Pleasure talking to you today and your patient hearing to the concern we are facing currently, Pls find below details of my plasma tv Model TH-P50V20D / Bill no -/ DOP 18 oct -2011 /
I would like to bring to your notice that as per attached pictures of my Tv there is a spider web type breakin on the internal glass of the screen which happened all by itself with a buzz while tv was in operation for around 2-3 hours.
I was being told by the technician visiting us today ( while I complained under ref no ) that it is a physical damage which led to such a situation, we refute the claim STRONGLY as we were watching and suddenly the tv stopped working after a buzz ( we have no reason to be UNTRUE with facts here for sure.. ) . As i am made aware,such incidences are not new with plasma technology or with Panasonic or any other brands and failures do arise which have been reported by other plasma consumers earlier extensively EVEN in the threads below all over the world and is a very common problem due to poor wms

below quote 2 explains the situation further
Sometimes and internal component can suddenly blow with enough force to crack the plasma panel from behind. That would have been the loud boom (probably more like a pop or snap). It has historically happened mostly on Samsung and LG plasmas, and there have been a few reports of it happening on Panasonics as well.
the outer glass is intact and the inner (plasma) glass is what's broken, then that's good evidence that a component failure cracked the glass.
Boards fry, panels break.
Along with other serious researches and quotes as below
Quote 3
Thermal fatigue is the most important failure mode in plasma screen casting. Thermal fatigue cracks may be classified by their appearance in heat checks and stress cracks. The characteristic feature of heat checking is a net-shaped crack pattern which occurs predominantly on level surfaces due to change in surface tensile stresses. Stress cracks mainly appear as individual and clearly pronounced cracks as a result of stress concentrations due to the configuration of the cavity. Generally, thermal fatigue cracks will already appear after a few thousand cycles or even much earlier, i.e. in the low cycle fatigue regime.
Quote 4
Since glass is brittle and thermally insulating, significant thermal stresses, especially in larger components often lead to catastrophic failure. The warm expanded glass inside pushes outwards on the outer layers of glass, forcing them to be stretched with very little tolerance for being stretched and cannot expand very far without breaking. Any existing microscopic crack on a stretched surface will grow all the way through the thickness of the glass, abruptly.

We have bought this unit on LOAN and HARD earned money and had done a extensive research before finalizing Panasonic due to your extensive experience in manufacturing plasma screens and being superior to any other brand in terms of service and technology, it is fairly understood that it is a ONE ODD early technical failure and manufacturing defect of the screen and components which should be investigated thoroughly and is completely shattering our this belief currently and we seek your help to review our case with compassion and help replace / repair the unit earliest being just 10 months old and still covered under primary warranty and extended warranty of 2 years as well.
We have complete belief in the brand and its people backing it up and are sure we all superior std's of BRAND until now would be upheld.
Look forward to earliest swift resolution and response.
Warm regards
and can you beat this I got 1+ 2 +2
