Hi,
I want to apologize first for the bad news I will give you!.
The crack on your panel is NOT repairable.The plasma display panel is trashed!
This panel is made with a low pressure vacuum inside(like a fluorescent tube-once broken it cannot be repaired,just replaced).
Once it cracks ,all the vacuum is gone..the tv will need the plasma display replaced.
The panel is available at mcmelectronics.com,but its price is over $1500.
See the link please:

At this price you can buy a new tv.
I know ,that your husband will not be very happy ,but this is the situation.
Please let me know if anything else I can do for you.
Thank you and have a good night!
