Screen got smashed

Vertical scan output section circuit should be checked. Contact any service technician.

No, not really but you need to know specific information to make sure the one you get is compatible. If you're good with electronics you should be ok doing it yourself but this seems like a good deal:

The display would have got damaged and might need attention by a qualified service technician.

Most of the times smashed screen means the end of plasma tv. Although if your tv model is older than 3 years, you could search for same model broken tv's with working screens since power supplies usually last for a few years in modern flat panels. Though you will need a qualified serviceman to do the assembly from two faulty units into a working one.

Nothing that a new screen won't fix. Problem is the price will be more than the replacement cost for a new TV.
Have a look on the manufacturers web site for an authorised repair workshop that will give you a price.

Yes it can be fixed most certainly. You have broken your Plasma screen and most certainly scratched your filter glass with the broken screen glass inside. Depending on where you bought the TV, and whether you have a cover plan, you may get the Tv screen & Filter replaced under accidental damage. If the TV is still under warranty and you dont have a cover plan, you may find the repair will be refused. If so, you could maybe buy the same tv off ebay as repairs or spares and fix yours.

it's likely the bottom LCD screen has been damaged in some way (or smashed) the bottom LCD will need replacing (touch screen may need replacing also)

The price of a new tv - the screen must be replaced (it's unfixable) and that will cost almost as a new tv.

Not likely, you'll most likely have to get a brand new TV.
