I'm having problems with booting up my PS2. When I insert a disc it now doesn't automatically boot. Instead it goes to the browser screen and I have to load the disc that way. Once it's loaded it's fine but I think there must be a problem with my disc reading lens or something? Is it possible to clean the lens or have I got some other problem? I don't know if these things are connected but I also have a problem with discs occasionally not recognising that I have a controller in port one. I often get the message "please insert a controller in port 1" even when a controller is inserted. If I switch to an alternative controller it then works. Any ideas? Thanks in advance to anyone who can help me with these problems.
