Lightning strikes on screen and takes awhile to warm up then fine


sorry its not an easy fix at all. im sorry wat you have to hear, but do you have kids? if so, they probably bumped into or hit the screen. that would result in permantly damaging the screen

Hi,

Yes, the screen can be replaced. The screen is comprised of 3 screens. The Fresnal Screen (inner screen), Lenticular Screen (middle screen), and the Protective Screen (outer screen). Please see below for links to these items.

Need all 3 to complete screen assembly.The only screen that is still available is the innermost screen, which is probably not the 1 you need. You will only be able to find the middle (lenticular) and outer (protective) screens from a distributor that has them in stock as no one will be able to order them from the manufacturer.

  1. Fresnal Screen
  2. Lenticular Screen (no longer available)
  3. Protective Screen (no longer available)

Black Box


Hi Krautner, We have a Toshiba and experienced the same problem this morning. It is very similar to your symptoms: big black box in centre-lower part of screen. It sometimes disappears momentarily when you select a feature such a "mute" for the same amount of time the screen displays that function. Once the "mute" signal disappears, the black box comes on again. I fixed the problem by turning off the close captioning function. Somehow, it had actually got switched on. It runs fine now. I suppose you have already found a fix since you posted back in May....but hopefully this helps you or someone else putting in a similar search for this fix. Cheers Geo
