Nokia/E51
Phone screen blank within 2 months of purchase

I had bought a Nokia E 51 on 13th July. 15 days back the screen went blank on its own. I sent the phone to the service center and they gave it back to me 3 days back on 25th September. They said the LCD has been changed. Yesterday again the screen has gone blank. I wish to lodge a complaint in the consumer court also for the same. I will be finding out the procedure and going ahead.
