Hi..i have a sony BDP-S300

Question

Hi..i have a sony BDP-S300 BLU-Ray player.I have had it for 3 months now with no problems.But all of a sudden i will be watching a movie and it will just stop and go to a blank screen.The disc is still playing because i can see the dial still clocking.Sometimes it lets me go to the menu and go to scene sellection,the movie plays but with no sound.I have to power it of and start again but the same thing happens five minutes later.Please help.
