Projection TV screen repair
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. Thanks, Mark |

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.

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 screen. |

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. Leonard "Travis Jordan" wrote in message ...

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