my daughtr just broke our 40" lcd tv, any one knows wher to fix or find a new pannel and howmuch it costs. tha

If the TV is more than 2-3 yrs old, it will probably cost more to repair than it is worth. I gather that you mean the glass is broken--if so, that is the most expensive part to replace. Call a factory-authorized service shop (look in the phone book or call the manufacturer) call them and describe what happened. They should be able to give you a rough estimate over the phone.

from my personal experience, LCD screen will cost you around 70% from the price that you paid for the TV set.

If you bought it for 100$, the screen price is $70. It is not quite worth it. but you can try.

Good luck!
