Dust "under" LCD Glass

I am considering purchasing a used M240 with a flaw. There is dust under the cover glass of the LCD. While I am not bothered by it, it does make me slightly concerned about the sealing/longevity, particularly if some rain will short the LCD and break the camera, or such. I just don't want to buy a ticking time bomb. Does anyone know if the presence of dust under the LCD indicates some failure of the seals? Is it still usable for extended periods, years perhaps? And, any idea of a replacement cost, or the ease of DIY? The attached photo is a depiction for how it looks. Thanks.

Difficult to tell from the photo, but it is possibly a smudge of some sort under the lcd « protector » . In this case, it is just an annoyance. The protector sheet is really of no real use, the lcd glass is quite strong and does not scratch easily, at least, mine hasn’t for some years of almost daily use. 
This camera is not “waterproof “ but I have used it in pretty bad weather without issues.
You should ask the seller about this.

Thanks for the reply -- the seller clarified that there is no screen protector (as in, nothing aftermarket) and the "dust" is behind the glass itself and invisible when the LCD is on -- in that case, I presume it should be no problem?

Hi,

Whatever the the stuff might be it surely is not dust. There is no way for dust to enter under the glass, so it must be caused by something else. 

Purchase the camera if you want, but caveat emptor. Sounds like you are buying from someone online or privately, so double caveat emptor. There is no lack of M240 or M-P(240) available from Leiva dealers who will warranty the camera, you may want to check some of those out.

Thank you very much, it is great to know that the LCD protector is the problem and can be cleaned/replaced. That sounds much more affordable than a potential LCD replacement I was expecting.

To anewbie:

You wrote that the seller told you that the camera had no screen protector. So it is not a matter of replacing something that isn’t there. Why would you want to spend money to repair something before being happy with using the camera. Use a bit of patience and find a warantied unit.

Fair enough. Oddly, it is from a well-known eBay seller with a 90d warranty. I am confused why they did not fix it.

As you say it is not a user add-on protection screen, I think the issue is that the Gorilla glass screen (sometimes referred as cover glass or screen protector) is bonded to the LCD as a single unit,   There have been cases of dust getting between this outer glass screen and the LCD (as seems to be the case with this camera).  I believe that to fix this problem Leica has to replace the complete LCD/cover glass unit, they will not clean or replace just the cover glass. I recollect the cost of this repair is around $1000.  Perhaps you can get the seller to reduce the price of the camera to allow for this.

Should say LCD not sensor

Looks like an add on screen protector to me. Easily removed.
