MY LG 42 INCH LCD WAS DAMAGED THE SCREEN AN OBJECT

it depends on the severity to know what all is damaged, is the "object" embedded in the screen still, did it crack the screen, do you see anything on the screen, And we will need to have the exact Make/Model of TV to suggest any parts or prices/repairs, I'm sorry that happened to you, I am ultra paranoid about that happening to mine (52"), I hope this helps, please give a fixya rating if it helps solve your problem

IF the damage is so bad that the picture is at fault than unfortunately there is only 1 option: to replace the complete panel. This however is too expensive since the kost of e new panel would mostly be higher than just buying a new TV...
