Question about DVD & Blu-Ray Players
"No valid disc" comes up on the screen when I put a disc in. Has not always been a problem. Toshiba SD-P1900
SOURCE: No Valid Disc - Toshiba SD-P1900
one thing I tried that works so far, (now I jinxed it) is if when I put the disk in and close the dvd cover and I don't hear it starting to spin, I turn the machine off and then back on again...so far so good.... Technology rules!!!

If the units under warranty you may want to contact Toshiba as it sounds your unit is in need of a replacement laser assembly.
If the unit isnt under warranty, Toshiba should be able to supply the parts you need and as long as you mark every thing that you remove, as to know where it goes when re-assembling the unit. The lasers arent difficult to replace. Good luck.

how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it cannot read data/files on DVD discs.
To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or a mechanism problem.
Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.
If non of the above solves the problem, then know that you need to replace the laser to a brand new one.
To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.
Once this us done, your player will play all DVD discs again.
