Barlow, forget about this plasma, it's too risky buying it. The problem is not the glass but what the glass had damaged when it broke. Which could very well be pixels from the front of the panels.
Now, it is possible that the only thing broken is the glass, in that case you have to replace it with the original part and nothing else, it's a special formulated glass.

Here is Philips toll free # if you ever need it: 1-800-451-2851 and ask to connect you with national parts which is located in Knoxville tennessee.
