Sony BDP-S350 EXT MEMORY PROBLEM

[Sars]

Hi, Im hoping someone might be able to help me.

My player wont play any discs.

When you press select to play, a pop up msg appears. It syas to check the EXT memory at the rear of the unit and to turn off and on the player. I do not have anything inserted into the memory slot at the back and have turned it off and on but it still does not work.

Can anyone help me or should i bring it back to the shop. Im absolutely gutted. I already had to bring it back a couple of weeks ago because the LED display on the front stopped working.
