Most common problem with portable optical devices is the laser height gets out of adjustment. All lasers are adjustable but it varies on how to adjust. Usually you just disassemble it enough to view the (usually) plastic cogs that adjust - as you turn them you can see the laser change height until it reaches the top and then it drops back down. I just bought this DVD device and was checking around for reviews. But haven't seen the problem on this so can't speak to specifics.

Re: message "check disk"
Given that you have checked the owners manual for possible solutions & have tried more than one DVD, then the problem sounds like corrupted software in the player. You should return the unit for a replacement.

There was a bad batch of spindle motors (why they didn't use brushless is any body's guess). I replaced mine and it is quite easy. I even soldered in the single-DVD player's (same basic model number, just not multi-disk) motor because I couldn't find the right part for the multi-disk model (or the single was cheaper, I forget). That was years ago and it still works great today (I didn't like the lack of features on a cheap replacement player).
usually this happens when lens cannot read the the disc. Due to few reason
1 Your disk is scratched
2 Your DVD lens is covered with dust
3 You need to replace DVD lens Try another few CD/DVD to rectify whether there is any problem with dvd you are trying to play
if this error occurs on all the dvd you played then the most likely proble is with your DVD lens
either its coverd with dust use Disk cleaner if not you got to replace a new DVD lense as per model
The problem is you need to replace the laser assembly if the disc is spinning and not being read, or if the disc isnt spinning, you need to replace the mpeg printed circuit board attached to the laser assembly. Good Luck.

if the disc doesn't spin, it sounds like a bad motor. can you hear the laser adjust? if you do, then it's probably a dead motor, if you can't hear that laser adjust at all, and the motor doesn't spin at all, the connection might have come undone(they both share a connection)
There is a solution but it takes a little care because the wrong thing touched will give you a shock. Just stay away from the unit near where the power lead enters the unit.
OK. remove the top of the unit, place a disk in the unit press play and gently give the DVD a gentle push in a clockwise direction.
This disk should then get up to speed and start playing. It also unlocks the error. No guarantees with this one some work, some don't. I hope yours does.
