Question about DVD & Blu-Ray Players
Put in a DVD and display reads No Disc.
I had that problem, the problem is that where you put the disc (the black Circle) tends to get a bit loose so it moves downwards.
so the distance between the lens and the under surface of the DVD / CD is reduce, so the beam is NOT return to the lens.
The way I fix it is by pulling the black circle EXTREMELY carefully and SLOWLY while you are turning it.
Once is out, with a toothpick or a needle put a small amount of crazy glue in the inner walls of the hole that is in the center ( where the pole of the rotor goes in) this way the hole is reduce.
Wait till it dries, then gently put it back in, it will be a tight fit, IT MOST NOT GO ALL THE WAY IN!!!
By this i mean that you will see the pole of the rotor go into the hole, but it most not reach all the way, it should be below the surface. The distance between the end of the pole and the surface of the black circle should be THE THICKNESS OF THE BLACK CIRCLE.
The way to know that the distance is right, put in a CD and play some songs, then try it with a DVD.
If it reads no disc it means you inserted the disc to much, pull it out a bit, then try again.
Once it reads both CD and DVD, fill in the hole with a drop of crazy glue, this way the black disc will not move anymore.
One more thing, I do not recommend to use alcohol in the lens, 'cause some lenses are now made of polymers non resistant to abrasive, instead use a cue-tip (cottonete, little pole with cotton to clean your ear) moistened with bottle water or distiled water.
Note MOISTENED not soaked or wet.
Hope it works for you.
