Liteon dvd recorder

Hello, dont know if anyone can help, but i have a liteon dvd recorder,model lvw5005b, the drawer is not working, keeps opening and closing, wont recognise discs at all, think its broke, is there anyway to replace the dvd burner/rewriter??? if so which is the best one to buy? does it have to be the same?
hope this makes sense to you ,

DID U try to uninstall Drivers in Device manager,then restart your computer. Windows will Re-Install upon Reboot, this might help
