I know I'm a cheap a$$, but I bought a Classic DVD50S DVD player about a year ago. I dont have a warrenty on it. Recently it wont let me play dvd's on it. i load a dvd in, and then it says error message "no Disc". while it says it's loading it makes these weird ticking sound. i tried cleaning the lens and such. the odd part is that it will play music cd's but not dvds. thanks.
