Liteon LVW-5005A Problem

Hi everyone!!

I purchased a LVW-5005A last October. Everything was working great until last week.
The problem NOW is the recorder won’t play or record CD,VCD, or SVCD’s. Even the copies I made on this machine won’t work. DVD’s are fine. No problem in playing or recording.

Is this a mechanical or a software problem??

Note- last week the rubber belt in the tray mechanism came off. I reattached the belt. May an alignment problem??

Please help
