Some Home dvd players may not have any adjustment abilities, but you would find such things not too far away from the lense, if they don't exist, get a new unit.


There are two tiny surface-mount potentiometers (could be capacitors also) sitting in the small circuit on laser assembly.

this is exactly response I would like to hear - an expert opinion!

What I did with help of 1mm-wide screwdriver:

1) There were two surface-mount potentiometers marked with C1 and D. I tried first D. Turned it clock- and counterclockwise by about 45 degrees.
2) After each turn I opened and closed tray to force the player read DVD disc.
3) It did not help, "NO DISC", then I tried the same with C1, and again, no luck.
4) Finally, I came back to D and turned it by about 180 degrees in one direction. IT WORKED!!!

Moreover, seem that now player reads content of the DVD discs faster then before. Probably manufacturer did not really adjust it properly and upon the time something has degraded, so it failed eventually.
