I have a portable DVD Player of Model DVP320/69 with top opening. My problem is that when I insert any CD/ DVD, it is showing loading but after sometime it is showing NO Disc. Is there any problems in parts or any thing else. I have already show it in a service center but they could not fix it. I came to know from them that the lesser is OK. Will you help ME? My mail ID is "rm_dds@rediffmail.com". Thanks..
