I have a Panasonic SC-BT303 bluray home theater that suddently stopped reading dvds. It was after a blackout. It reads BluRays, MP3 discs, but not dvds. It says disc not read.

    I thought it was the same laser for reading both media. Could you give more details on this?

Most likely this a problem with the laser itself. How long have you owned the unit? Being that its like a 400$ system most likely it won't be worth it to have the unit repaired. If you have available inputs I would just use a separate dvd player for DVD's. If you have any other questions please let me know.
Thank you,
Lee

    Hi, actually the actual laser that reads the disc is different. It all gets very complicated but here is a short explanation.
    While a standard DVD
    uses a 650 nanometer red laser, Blu-ray
    uses a shorter wavelength, a 405 nm blue-violet laser, and
    allows for almost ten times more data storage than a DVD.
    From what you described the blackout damaged something and given price of the unit repair most likely isn't worth it, unless you want to spend the money then I would contact panasonic and inquire about repair. Myself I would just use and use a different dvd player as a work around.
    Thank you,
    Lee

My harman kardon player will read blurays, however it wont read dvds. Any idea why?


More than likely the lens that read dvd discs has failed. On blu-ray players, there are two (2) optical lens. One reads blu-rays and the other dvd/cds. They are independent of one another.

My sharp blu ray player no longer plays blu rays


If it plays CDs and DVDs but not BluRays at all, then the blue laser is burned out. CDs and DVDs use a different laser. A needed firmware update would not prevent it from reading a BluRay.
