I have a portable dvd player that can't seem to load dvds. It knows when there is no disk present, and it can see and play a cd. I blew all the dust out, and I cleaned the lens with alcohol. No change. I pulled the ribbon and its contacts look ok. The laser lights up, and the assembly goes forward,up and down a few times, the back a little, and tries again. I can hear it making little tones, but it will keep trying forever and never play. Ideas?
I was having something like you describe happening to my "Nintaus DVD"in my case the disc would spin up and play almost to its conclusion and then it would freeze I tried cleaning the lens etc nothing along those lines worked until i removed the whole tray that the lens mechanisim is retained by in my case i was then able to see the underside of the mechanisim on this model there are 2 potentiometers for alignment purposes i found out about this in a repair book anyway the 2 pots are....1 for cd and one for dvd the machine reads in binary that is zero's and ones well if the alignment gets out of whack you get freeze ups and flickering etc anyway try turning these pots with something insulated only a very small amount and test, Some dvd's have "dvd" or "cd" marked on the circuit board in my case they were not marked so it was adjust one then test,If you decide to try this make sure you earth yourself using the metal case or ideally use an anti static wrist strap the main other thing is when you adjust do it in very small increments my dvd is only a cheap one that i thought id have to throw out so far it is working fine again, Its sort of flying by the seat of your pants re the adjustment as there are no instruments at hand unless you have access to someone who does. If you try it i wish you luck, the suggestions other people have made are all valid things too re a weak diode its great if you can fix it yourself. I just re read your post if as you say the unit will play a CD ok then you only need to adjust the DVD pot

The DVD portable player and the DVD disc came from the same countries?Ur DVD portable player and DVD disc u are using might have the wrong region DVD disc format frequencies.Like PAL frequencies only play Euroupean,Asia,Middle East,Austriala and Africa products.NTSC frequencise play only USA,Canada and Mexico DVD Disc products.
The message indicates that the system failed to read the index portion of the disc. Try cleaning the lens using a cotton swab and alcohol. Try playing a music CD as well. If hte CD plays but the DVD continues to fail, you have a failing optics assembly that needs to be replaced. This is the most common symptom of failing optics. DVDs will fail while CDs will play.
Keep us posted.
Try playing Different DVDs, Second Make sure which Region Disk your playing is it Region 1 or Region 2, If your DVD player is Manufactured in USA it plays only Region 1, If its manufactured in UK it plays only Region 2, If still you face same problem Use Lens Cleaner, If still you face same problem do Reset.
To Reset Dvd player, Remove DVD from Dvd Player, Unplug Power chord from Walloulet for 15minutes so player goes to Defult Factor Settings, Then plug back again Power chord. Turn on Dvd player insert DVD, It should Play or else Claim Warranty.
Chances are, your DVD player uses one laser to read CDs, and a different laser to read DVDs (since Cds and DVDs are read at different wavelenghts of light). If the DVDs you're trying to watch work properly in other DVD players, it probably means that the DVD laser is dirty, damaged, or burned out. Though you can try cleaning the laser (use Google for suggestions on how to do this, or check the Audiovox website), you will most likely have to get the DVD player repaired, or buy a replacement.
Many of the newer CD/DVD players sold today use a single combination laser, which reads both CDs and DVDs, which means that when the laser fails, it will not work at all. Wish I had better news for you, but I guess that the only consolation you have is that your Audivox player still works with CDs...
