I have a TH50PX60U and the screen is damaged. Not the external, the layer beneath, it appears to be a mesh-like material (hard to tell). I have a back-ground in electronics and if I could identify this, I would order it and attempt the replacement. Any ideas? I am also looking for the service manual, from what I understand, Panasonic wants $30, I am looking for the freebie though.
It would be so awesome to get this up and running, any help would be greatly appreciated.

When it comes to repairing a flat screen TV, there is a wide range of issues that can cause problems. The most common problems people seem to have are screen and picture-related. As long as whatever damage to the screen has not penetrated the layer of plasma or LCD pixels behind the screen, repairing the flat screen TV is possible. If the damage is too deep, it may be necessary to replace the TV altogether.

This looks like impact damage :( If it was changing with the image I could tell you sure, it's a digital issue and probably is a result of bla bla bla...but because it remains perfectly static no matter how the image beneath it is changing, I regret to inform you I believe this damage is physical.
Likely caused by an impact to teh screen - you're only option is to purchase a new one or get it serviced, hopefully you have a warranty! :(
that is usually caused by cleaning the screen with windex the windex runs down the screen bewteen the screen and plastic frame and actually seeps inside between the screen layers. Eventually it may go away by itself if the circles are not too bad but in most cases the damage is permanent.It can also be an issue called screen delamination which there is no fix for.
I hate to bring bad news but it's better cruel truth than sweet lie. You got so-called "physical damage" of your LCD panel. Surface that you can touch and one that looks intact is just a protective layer. Behind it is fragile class of LCD panel. Sometimes kids tap toy into the screen and parents later guessing what's wrong with TV. No manufacturer (that covers first 12 months) or extended warranty will cover this repair. Technician will show up for free of charge, take a pictures of the screen and leave you with this problem. Whole LCD panel have to be replaced and part alone could cost up to 80% of cost of new TV. Unless you can prove that this is shipping damage (I doubt it because it is not that you calling retailer very next day after purchase) - there is nothing that you can do to get out of this situation cheaply. Still you need to call manufacturer customer service and have technician from authorized service center to show up and inspect it. Maybe we both wrong and you have a case of defective panel. Really hard to determine without seeing pictures of how your LCD looks like. Sorry again and good luck! Russ.
This is usually caused by dirt trapped between the lcd filter layers and appears when the screen is pressed, pressing the layers togehter producing an internal dust smear..This can only be removed by stripping the lcd down and cleaning the filter layers
Unfortunately the LCD panel would need to be replaced. Even if there is not any signs of damage to the outside portion of the panel, one of the inner screens may have been fractured. I am not sure if the panel would be available because if i'm not mistaken Sharp just started making replacement panels.
