brill64 Posted October 11, 2009 Share #1 Posted October 11, 2009 Advertisement (gone after registration) i know this issue has been mentioned before in the m8 forum however i am unable to find it for reference. my m8.2 led display has at some point developed a dark rectangular patch between (i guess) the sapphire glass and the led mon. it's hard to describe what it is exactly which is why i'm asking here because it will be sent it in for service and other issues in ten days or so. it looks like moisture/sweat ingress maybe or perhaps mould although the camera has not been dunked. it is easily visible with lighter background shots viewed with the camera at an oblique angle on the led mon. could anyone kindly help with similar experience and/or a description of what it is for the service record? i'm not sure how to describe it to the service centre guys Link to post Share on other sites More sharing options...

mboerma Posted October 11, 2009 Share #2 Posted October 11, 2009 Maybe you should look for LCD display and not LED display to find the post(s). I haven't read anything about this before. Link to post Share on other sites More sharing options...

Nicoleica Posted October 11, 2009 Share #4 Posted October 11, 2009 Hi, I believe that this is known in the forum as the 'Coffee ring' problem, and is caused by de-lamination of the lcd from the glass. Link to post Share on other sites More sharing options...
Tinribs Posted October 11, 2009 Share #5 Posted October 11, 2009 Hi Brill First time posting on these forums, so bear with me. If its any comfort, I too have the "coffee ring" problem, in my case on an M8.2 about 6 months old. If it is caused by de-lamination, as Nicole suggests, in my case the camera has spent several days on my desk, screen to a South-facing window. It looks as though excess warmth on the screen might be a causative factor. (We do get sunny days, even up here in Cumbria ).Guess it will be back to Solms under warranty once I persuade myself that I can justify an M9 to act as replacement!

brill64 Posted October 11, 2009 Author Share #6 Posted October 11, 2009 thanks people for your common sense..."the coffee ring", that's it! delamination, thank you!. lcd not led, that's why i couldn't find it.. my warranty period finishes in a couple of weeks, this and all kinds of weird lines have been appearing on my pics recently so i will finally bite the bullet and be without it for 6-8wks. i use one camera body so i've left all these issues until the very last minute. i love my m8.2 and very much hope this love affair can continue long after the warranty is up Welcome, dear visitor!

Guest WPalank Posted December 12, 2009 Share #7 Posted December 12, 2009 Advertisement (gone after registration) Brill, Sorry to say, but that is not the classic "coffee-ring pattern" that typically shows up on the LCD (look at sfokevins image above). It looks more like broken sensor glass as in this thread: http://www.l-camera-forum.com/leica-forum/leica-m9-forum/108712-ir-absorbing-cover-glass-broken.html Have you physically looked at your sensor yet?

Brill's two example pics show completely different image flaws... I don't think that would be caused by a crack on the sensor glass - A cracked sensor glass would manifest a flaw that would be more consistent and run the same direction?... And I might also add that the image flaws in Brill's second post do not match what he originally stated was his problem Link to post Share on other sites More sharing options...

And I might also add that the image flaws in Brill's second post do not match what he originally stated was his problem i stand corrected, sfokevin. i guess i saw this post as a chance to vent some other issues i was also experiencing and hoping to get comment on and fix. sorry about that! after looking at above images, the leica technician decided immediately to change the sensor for a new one. the abberration shown by the last image may be a fault of my 75lux but i've yet to repeat it. the "coffee stain", however somehow disappeared and i found myself unable to explain the issue clearly enough to him to warrant further investigation. alas..it seems only to appear from time to time or as the weather changes..

If your problem was condensation in between the LCD and the plastic/sapphire cover and has now disappeared (Basically the condensation has evaporated) - I would bet it will reappear!... The problem is the plastic/sapphire cover seal has been compromised and condensation can come in... and it will come in again - overtime it will bring in micro dust particles in that will not disappear...

jaapv Posted December 14, 2009 Share #11 Posted December 14, 2009 The images show flare, reflections and OOF obstructions in front of the lens. Link to post Share on other sites More sharing options...
brill64 Posted December 14, 2009 Author Share #12 Posted December 14, 2009 yes i agree..i want to get this fixed but i need to be able to put something physical in front of the technician first or he's going to think i'm nuts. it was very noticeable a couple of months ago but i was too busy to put the camera in for any length of time. now the weather is less humid it's disappeared. my loss. thanks for your input anyways, guys! much appreciated..

jaapv Posted December 14, 2009 Share #13 Posted December 14, 2009 You might be disappointed about the repair. Somehow - I cannot understand why- this seems to be quite expensive. Link to post Share on other sites More sharing options...
sfokevin Posted December 15, 2009 Share #14 Posted December 15, 2009 You might be disappointed about the repair. Somehow - I cannot understand why- this seems to be quite expensive. Upgrading to the sapphire crystal cover could be an option... it is equally expensive but you get an extra years warranty too... I would just compare that to the repair cost out of warranty. And as a guide to the repair guy - just show him this pic - he recognize it: Link to post Share on other sites More sharing options...
