Hi. I cudnt switch on my Sp 550UZ after couple of months staying in its box. I brought it to Olympus service shop in Vietnam and they said shud replace chip or mainboard and this cost USD100(!!!). Too much for me! Anybody has broken SP 550UZ in Singapore, which can sell me this chip or mainboard? Or can show me anywhere in SIngapore I can repair my camera w. lower cost? Thank you for your help!
