1st, I think the term 'Expert' is used too loosely here, at least for me. LOL. I just had the pleasure of fixing an IDM-1731 with a 'No Disc' error. It just so happens that calibrating the drive helped me out.
For any of you that feel like taking a risk & opening up your player, I urge caution when handling the optical lens. There are 2 pots located above the ribbon on the end that connects to the lens to the left. The 1 on left I touched to the right & that helped me out. I'm thinking that the vibration caused the player to get out of whack as time goes on.
After getting the player to work, I took measurements with my multimeter. The left pot measures 3.06 k ohms & the right measures .965 k ohms. I hope this helps others out as it did for me.

I'm sorry that the DVD player is not playing discs are expected. Based on the information you have provided, it appears that the Lens head of the DVD player is dirty. I suggest that you use a lens cleaning disc to clean the lens head and it should resolve the issue.
Thanks for understanding. Please let me know if the issue persists.
It would more likely be the types of discs used. They are either of a region code not compatible with the player, contain foreign/unknown data, or they are unsupported formats. For example, if the player supports DVD-R playback, and you put a DVD-RW in, the player will generate 'wrong disc' message if the player cannot recognise the disc or the contents on it.
The disc formats/types that can be played should be outlined either on the unit itself or in the instruction manual (if you still have it). If the player shows that message even with genuine shop-bought DVDs then there is a defect within the unit, workshop attention may be required to fix it, but it could be costly.
'WRONG DISC' usually means the disc inserted is of a different region code to the player, or the wrong format (DVD-RW instead of DVD-R as exampled above). Try using different discs before going any further.
Now u put in a DVD movie disc into the DVD player slot.The DVD disc still register on the tv LCD screen,but just don't read the DVD disc?Yes.Tries websites like Amazon.com,Ebay.com to buy a DVD cleaning disc kit to used to clean the DVD laser eye of the DVD player slot,after this it should work.If tv still have the same result,than this tv problems DVD player slot can't be fix or worth fixing because the DVD player slot laser eye is bad or dead alredy.
Most AVI files from the torrent network use codecs to compress the size of the file you are downloading, and most DVD players only support the basic DIVX codec. A way to get around this issue is to use Nero software on your PC to burn a Video DVD. Selecting this option will make the program decipher the data and write it to the dvd as a compatible format with your standard DVD player.
If you know for a fact that the discs you are putting in, then there is obviously something wrong with the DVD player. When you put a DVD in your player, can you hear it spinning the disc at all? If your DVD is not even spinning the disk, I'm afraid your DVD player might be toast. If it does spin your discs, try a lens cleaning disc (available at pretty much any home electronics store or large chain store that sells home electronics). If that does not help, let us know and also let us know if you would be comfortable opening your DVD player.
are they bootleg dvd's? if not try getting a lense cleaner because wrong disc means it's reading your dvd's as .mov files which only play on quicktime in a computer. if it reads your cleaner as wrong disk too then get yourself a refund cuz it has a motherboard malfunction.
is the dvd a store bought disc or a burnt dvd? If the disc is a store bought disc I unfortunately can't help you. But if the dvd you are trying to play is burned from dvd burner you are most likely using the wrong type of burnable dvd.
There are two types of dvd's you can burn, DVD-R and DVD+R. You need to make sure which one you dvd player can play, some play one or the other, some play both. I have also heard of some older ones that can't play any type of burned disc.
Hope that helps
