    I've got a 52 inch Toshiba rear projection TV. I also have a 3 year old
    son. Yadda, Yadda, Yadda. So where can I get a replacement screen for my
    TV. Are they all the same? Just the outside screen (the fresnel portion)
    is cracked.

  2. If the TV is older than the son, you might consider just replacing it.
  3. The outer lens is the lenticular, the inner is the fresnel. Call your local
    shops or Toshiba distributors with the model number. Expect to pay at least
    a couple hundred $ for it. If you measure the exact dimensions of the
    screen from behind you might get lucky and a local shop will have one the
    right size or one that they can cut to fit for cheap.

  4. FWIW, replacing the lenticular is not as easy as you might think. The
    lenticular screen is attached to the fresnel screen in a specific way so
    that the fresnel screen is allowed to hang freely, which prevents it
    from bowing. It's very easy to get small bits of debris in between these
    two screens when assembling them, which can make visible shadows on the
  6. What is so difficult about it and what is this "special way" of which you
    speak? The biggest problem is static electricity attracting lint, packing
    foam, and dust. Many of the screens are taped together at the edges and
    this can be a PITA. Never saw a service bulletin from a manufacturer, nor
    special instructions about how to hang a screen. Sounds like a scare tactic
    to ward off the DIYers.

    I would check prices for new tv's if the tv is more than a few years old.
