For the no disc issue, there are always some common fixes that you can apply to make it functions normally. Here is how you can try.

Step 1:Press the "Eject" or "Open" button on the DVD player to disc tray to determine if it opens easily and does not appear jammed or hindered. If the disc tray appears to open slower than usual or fails to open, the disc may not sit flush in the tray or otherwise be seated properly. Use your hand to pull out the disc tray slowly if it does not open on its own and then reseat the disc. Close the disc tray and press "Play" on the DVD player again to see if reseating the disc in the tray corrects the "NO DISC" error.

Step 2:Remove the disc from the DVD player. Use a lint-free cloth and some denatured alcohol or water to clean the disc and remove any dust or smudges that may prevent the player from reading it properly. Reinsert the disc into the player and press "Play" to see if cleaning the disc fixes the "NO DISC" error.

If this still cannot work, you could try some other DVD player program such as Leawo Blu-ray Player and 5K Player.
