To start with, this is an internal failure as you might have observed. There could be many reasons for the same.It could be a faulty Z or Y board ( the cost of these board would be around $100 ) or it could be a a faulty logic board ( the cost of which would be around $75 ).Another reason could be a faulty inverter.You could rule out inverter by following the below technique ( this is not 100% foolproof, however would give you the best possible result without instruments ) :-
The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
Ideally,the inverter must be tested by reading voltages with a multimeter.
I am sure that the above information must have given you an idea of the repair cost. You need to add the labor cost and the shipping charges ( if any ) or trip charges if you call a tech to get it repaired.If you wanted to fix it yourself, revert and i could tell you the place to order service manual and then provide some pointers on how to fix this. However, you need to have electronics repair experience, should be able to read schematics and needs to keep all precuations to resolve this problem.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
