42 plasma samsung fault?

been reading the thread about the free samsung repairs. i have a PS42C45081W plasma. i can't see this model mentioned anywhere but it is doing exactly the same as all the others with the clicking, not turning on and no picture but sound. i have had it into a repair shop and it cost me £95, not repaired and took it back again, still faulty. do you think it is worth trying samsung for a repair?
