Lense Error

I have nikon coolpix s6.I have a problem with it.every time i am going to open it a white screen appears showing lense cover error.But lense civer is fully open.After sometime when the screen light goes off again on clicking
it is working perfect.I go to nearby Nikon Service center.They told me that disc driving mechanism is not working.So i have to repair it and it is costly.Please suggest me asap what i should do.Thank in advance
