Replacing polarized film on LCD TV

[Stoly]

Is it possible to replace the polarized film on a LCD TV?
Its an old LG 32" LCD TV that apparently was hit from direct sunlight while stored. The film cracked and peeled but otherwise its fine so I figured maybe I can replace it.

Can it be done?
Where can I get it?

32inch 0 degree 715MM*410MM LCD Polarizer Polarizing Film for LCD LED TV | eBay

Size : 714mm 410mm.

I don't endorse ebay in any way, but at least a starting point.

Given how commodity TV's have become, and because of the age and likely Pain in the *** factor that will be associated with this (getting the old one completely cleaned off, getting the new one lined up right, with no air bubbles or debris) - I'd just go get another TV. Another 32" can be found for under $100.

So, can it be done? I'm sure it can. I'm also sure it's totally not worth doing.

Now my question would be if a need a 0° or 90° polarized film. Somehow I'm assuming it would be 90° but I don't know for sure.

I mostly agree, but if this was cheap enough then it would fall under the "because I can" argument. I mean its not even 1080p, to begin with.

At $8, buy both. The one you don't use keep for stupid party tricks.

So I grabbed a small piece of film that fell from the screen. I put it horizontally on the part that was missing and it showed the image beneath, I then rotated it 90° and it won't show anything so I'm pretty sure its a 90° polarized film.

Well.. erm. I don't know if that's true. Any angle film you have - if you rotate it 90' will do exactly what you describe, because that's how polarization just works. It doesn't mean you have 90' film.

I have tried to fix broken flatscreens before TCON boards, ribbon cables etc. I am zero for 2 and the money I wasted could have gone towards a new one anyway. But if it's just 8 bucks and you're bored/adventurous/cheap then go nuts!

I think most polarized sunglasses are 90*. So you could probably buy a cheap pair of them. If you can see the image without tilting your head. 90* If you have to tilt your head a little, then it's probably 45* sunglasses. If you have to rotate the glasses a full 90* to see the image, then it's probably 0*.
