sebas_ Posted April 3 Share #41 Posted April 3 Advertisement (gone after registration) After careful analysis, I strongly suspect that the issue is related to static electricity, as a previous poster suggested. While I can't prove it with 100% certainty, multiple observations support this theory rather than a connection with ambient temperature. The pattern I've observed is that the problem occurs when I carry the camera around my neck on a strap as usual, with the display resting against my clothing and experiencing slight friction when walking. This completely normal usage situation appears to lead to static electricity buildup with certain materials like synthetic fibers (e.g., anoraks) or wool (e.g., winter coats), which then affects the display. Since these materials are predominantly worn in winter, this may explain why some of us initially associated the problem with low temperatures. I've observed this identical behavior on two different M11-P cameras. This theory also explains an earlier incident when the camera turned itself on inside my Leica Billingham bag in the car and displayed the same issue - the movement during driving likely caused friction with the top flap of the bag, similarly creating static electricity. Shortly afterward, with the camera on my neck, the display became extremely dark as shown in the attached image. Brightness was set to auto, but I also tested 100% brightness with no difference. I then switched the camera off, put it in the bag for around 30 minutes. Afterwards the behavior was normal again. This occurred despite the ambient temperature being approximately 10°C (50°F).

Andre1960 Posted April 3 Share #42 Posted April 3 (edited) Static build up during carrying the camera around my neck is my thinking as well. as long as the protective foil from the factory was installed I did not notice this issue. Only after removing the foil I started to see it. Cold weather is not the problem but I believe it is the combination of colder weather (+10 degrees celcius) somewhat windy and synthetic clothing. I purchased a protective screen from Leica and will install this and test again. Welcome, dear visitor!

petereprice Posted April 3 Share #43 Posted April 3 This sounds like an interesting theory but I’ve tested other M11 variants and not experienced this issue with the same conditions. In my case the M11 Mono does not exhibit this issue but my M11-P does. Any explanation for that? Link to post Share on other sites More sharing options...
Stranger on streets Posted April 6 Share #44 Posted April 6 I sent an email to Leica Germany and they confirmed as an LCD defect. They will exchange the camera as an initial defect. 1 Link to post Share on other sites More sharing options...

The edges turn light from the liquid crystal being cold. No, the center of the display starts dark as a small spot and becomes larger as time passes. Ofcourse it may look like that there is a reversed lens vignetting where the edges may look light but it is really the center that goes darker. it is visible in both menus and pictures which are played back on the lcd. see sample.

kiwidad Posted April 7 Share #50 Posted April 7 On 3/28/2025 at 3:23 PM, jaapv said: Sorry to get technical. And of course an individual camera can be faulty. But: Ambient temperature is only relatively important Moisture and air movement play an important role as well To arrive at a relevant conclusion about this problem you need to use wet bulb temperature. Which can be considerably lower. https://www.engineeringtoolbox.com/dry-wet-bulb-dew-point-air-d_682.html As for other cameras there is a difference in thermal dynamics between a compact all-metal body and a rubberized partly or fully composite one containing a lot of air. Leica M bodies are well known for difficult temperature management, both cold and hot. And another thing. On nearly all cameras the heat-generating motherboard is right up against the LCD but on the M10 and M11 it is offset to the side. This all adds up to not being surprised if CS returns a camera as being “ within specifications “. Or “konstruktionsbedingt” Wind chill doesn’t lower the actual temperature. If you blow 10 degree air across any material it doesn’t get colder than 10 degrees. Wind chill is relevant to the rate of cooling to the actual temperature. It’s relevant to humans in weather as it affects the rate at which a body can be cooled. An lcd is not affected by the “chill” Link to post Share on other sites More sharing options...
jaapv Posted April 7 Share #51 Posted April 7 And it is relevant in moisture/condensation conditions. It is called Wet Bulb temperature, which most certainly applies to an LCD in, for instance, misty, rainy or snowy conditions.. Link to post Share on other sites More sharing options...
algrove Posted April 7 Share #52 Posted April 7 Must check mine. How cold must one go down to in order to see this effect? Did someone mention Leica is replacing certain LCD's due to a defect? 1 Link to post Share on other sites More sharing options...

But it depends on the technology used, cooling down of the camera, moisture/wind chill etc. . Jaap is incorrect, Leica will replace LCD's.

Leica Repair generally sends you a document with what was accomplished. Thus it should say LCD replacement. Edited June 25 by algrove Link to post Share on other sites More sharing options...

On my repair receipt from Leica the only mention of what was done is “Replace or repair electronic / mech. assemblies.” It also mentions new: Leather Covering and Rear Cover, preassembled. They never used “LCD” on the receipt. It did come back with a new pice of plastic cover over the LCD so from that I’m assuming the LCD was replaced but not certain. 😂 1 Link to post Share on other sites More sharing options...
sebas_ Posted July 3 Share #60 Posted July 3 My camera has been at Leica for testing for a prolonged time . Thankfully I got a loaner in the meantime. Today I got the answer back, apparently it is a feature /s Translation: "We apologize for the delay caused by the extended testing by our quality management and development department. In rare cases, the LCD monitor of the Leica M11-P digital camera may become statically charged. This is due to the very low conductivity of the sapphire glass in combination with friction on certain textiles. The result is darkening and/or discoloration of the monitor. However, this is not a technical defect. The phenomenon is temporary and can be remedied or avoided by wiping with a commercially available anti-static cloth or by using a protective film. We ask for your understanding that no return as DOA or goodwill repair is possible in this context." Orignal: »wir bitten die Verzögerung zu entschuldigen, die aufgrund der erweiterten Prüfung durch unser Qualtitätsmanagement und Entwicklung entstanden sind. Bei der Digitalkamera Leica M11-P kann es in seltenen Fällen zu einer statischen Aufladung des LCDMonitors kommen. Dies ist auf die sehr geringe Leitfähigkeit des Saphirglases in Kombination mit Reibung an bestimmten Textilien zurückzuführen. Als Folge entsteht Verdunkelung und/oder Verfärbung des Monitors. Hierbei handelt es sich jedoch nicht um einen technischen Defekt. Die Erscheinung ist temporär und lässt sich durch Abwischen mit einem handelsüblichen Anti-Statik-Tuch, oder durch die Verwendung einer Schutzfolie beheben bzw. vermeiden. Wir bitten um Verständnis, dass in diesem Zusammenhang keine Rücknahme als DOA oder Kulanzreperatur möglich ist.« I am not really happy about that answer.... Sometime ago I had a sapphire glass Apple watch, which always came in contact with all sorts of textiles, that was no issue at all. 2 Link to post Share on other sites More sharing options...
