during a storm the power went off now my jvc dr-mv 150 will not recognize any disc - pre-recorded or blank. at first it stated wrong region now it just spins the disc and finally states unknown disc. i have unpluged the machine, cleaned the disc player and reset the machine to "factory set" nothing works. how do i get the player/recorder to recognize a dvd disc

I have a Sony DVD Recorder which has a mind of its own recorded discs it will not recognize some pre-recorded discs it plays ok does the lasers need cleaning or re-aligning
