You are advised to take the camera in to an Olympus Dealer near you, and have them evaluate the problem, and if they agree it's in need of servicing, they will send it to Olympus for repair.
If - at a guess - you are somewhere near Crieff or that region, the closest would be
Unit 4 Glasgow North Retail Park
G33 1AD Rob Royston
JRS Photo Hardware
PH1 5EH Perth
If you aren't in that region at all, please respond and let me know where you are or what town or post code, and I will get you the proper location information.
