I had a similar problem some time ago. I left it in with the camera shop at the top of Grafton Street who charged €85.00 for sending it on to Olympus in Germany for investigation. Any repairs carried out were an additional charge.
A couple of weeks later, I damaged the camera again and decided to buy a second-hand replacement model on ebay, rather than pay another €85.00 to be told that, as I feared, it couldn't be repaired.
The replacement one cost me €120 from the US.
In summary, buying a replacement may be a better use of your money than getting it repaired.
