cafecacao Posted July 30, 2018 Share #1 Posted July 30, 2018 (edited) Advertisement (gone after registration) Hello Everyone, After 6 months of use, I found out in my image there are 2 vertical lines as picture below (cropped, -2EV) when taking photo -3EV at over ISO 3200 I have double checked many other photos, 2 vertical lines only appear in the dark area of the photo or when I push +2EV at the dark area of the photo to +2-3 EV with lightroom and these 2 vertical lines only appear at 1 position on the frame of photo, other areas in photo IMO they are normal I understand that at high ISO 10k or 12k5 the image will appear some horizontal or vertical lines but not clear. I sent some DNG files to Leica for evaluation and I received the following response: "Please send the camera to Germany or replace the boards by yourself. There are too many pixel faultes. Please send the camera to Germany or replace the boards by yourself. There are too many pixel faultes. Kindly arrange to send your camera to us we will forward it to Germany for board replacement." And I sent a request to Leica to remap 2 lines by firmware only. Should I send my M10 to Germany to replacement? and how long will it be taken? I am confussing so much, IMO the issue is 2 vertical lines but they evaluated that having many pixel faultes Really need your advice. Tks all Welcome, dear visitor!

Ecar Posted July 30, 2018 Share #2 Posted July 30, 2018 "Replace the boards by yourself"? That's a strange reply from Leica... Anyway, it's unlikely that those dead pixels are going away and your camera should probably make the trip to Wetzlar under warranty. 1 Link to post Share on other sites More sharing options...
helged Posted July 30, 2018 Share #3 Posted July 30, 2018 For sure, send to Wetzlar. It will take some time, possibly 6-8 weeks, but the fix/repair will be covered by Leica. 1 Link to post Share on other sites More sharing options...

Sorry, this message from Leica Germany sent to Leica Singapore who forwarded to me again. Edited July 30, 2018 by cafecacao 1 Link to post Share on other sites More sharing options...
wlaidlaw Posted July 30, 2018 Share #5 Posted July 30, 2018 I suspect something may have got confused in translation. What I think Leica was suggesting was to try a different SD card to eliminate that as being the problem, even though it looks like a classic pixel failure.

Wilson No, Leica didn't suggest to try a different SD card, They just evaluated based on my photos. OK tks, I will try with different SD card and get back result Link to post Share on other sites More sharing options...
wlaidlaw Posted July 30, 2018 Share #7 Posted July 30, 2018 Advertisement (gone after registration) The German word for Card, as in SD Card is Karte. This word is also sometimes used for circuit boards. That is where the very odd instruction to replace the "boards" yourself might have arisen, as a mistranslation from the German. I am certain Leica would never suggest you delve into the innards of the camera, especially one under warranty. Wilson Link to post Share on other sites More sharing options...
frame-it Posted July 30, 2018 Share #8 Posted July 30, 2018 seems quite clear that it should be sent for repair..as they say "too many pixel faults"..if its under warranty just send it and ask the local store for a temporary camera Link to post Share on other sites More sharing options...
knobtob Posted July 30, 2018 Share #9 Posted July 30, 2018 I think the "by yourself" refers to the shipment of the camera not to the replacement of the sensor. Link to post Share on other sites More sharing options...
mdemeyer Posted July 30, 2018 Share #10 Posted July 30, 2018 Guys... read the thread. He clearly stated this was a response from Leica Germany to the Singapore distributor who forwarded it to the camera owner. So Leica Germany is suggesting that the Singapore distributor either return the camera to Germany for repair or do the replacement themselves in Singapore. There was never a suggestion the user would do the repair. 1 Link to post Share on other sites More sharing options...
cafecacao Posted July 30, 2018 Author Share #11 Posted July 30, 2018 Very sorry, made to confuse in quote from Leica. I can not edit my content so I re-quote below. Message from Leica Singapore: “Kindly arrange to send your camera to us we will forward it to Germany for board replacement. It’s best to get it repair before the warranty run out. Please see below email from Germany. Dear Ser, Thank you for your mail. Please send the camera to Germany or replace the boards by yourself. There are too many pixel faultes.” Link to post Share on other sites More sharing options...

cafecacao Posted July 31, 2018 Author Share #13 Posted July 31, 2018 I tried with different card but it is the same, no result, I hope Leica can fix by firmware. Link to post Share on other sites More sharing options...
brill64 Posted July 31, 2018 Share #14 Posted July 31, 2018 Upgrade to the latest M10 firmware & test again. Then email DNG file to Leica & ask for a firmware patch to fix the pixel fault. I had two dead pixels & they were fixed in this way recently within a few days 1 Link to post Share on other sites More sharing options...

I also thought like you, only need a firmware to fix. I don't know the way Leica evaluated. i don't understand here "board replacement" it means "sensor replacement". Confuse!!

mdemeyer Posted July 31, 2018 Share #16 Posted July 31, 2018 I’m curious if anyone knows why a single pixel fault would cause an entire row/column to fault. I can understand a firmware fix to interpolate a bad pixel or two (or ten) but interpolating out an entire row or column seems like bad medicine to me. Anyone who actually knows vs. wants to speculate, since I’m fully capable of speculating on my own? Link to post Share on other sites More sharing options...
jaapv Posted July 31, 2018 Share #17 Posted July 31, 2018 The sensor is a line scan sensor, which reads out the sensor in pixel lines. Depending on the damage to a faulty pixel, it can block the readout of the entire line. If the number of damaged or nonfunctional pixels is below the tolerance limit, the offending pixels ot pixel line will be replaced by interpolated values of the neighbouring pixels. Normally this will not be visible, however we had a thread with examples in the S forum a while ago which illustrated a kind of moiré effect from a repaired pixel line. 1 Link to post Share on other sites More sharing options...

I expect they mean the motherboard and they'll probably replace the sensor, send it to Germany, not the local service dept in Singapore. 1 Link to post Share on other sites More sharing options...

Every sensor as used for imaging comes with a certain number of bad pixels. Depending on the camera level AKA price, there is a certain number of faulty pixels that is tolerated.* Those faulty pixels are mapped out on production of the camera. If the sensor develops more faulty pixels, those can only be mapped out ("remapped") if they are within the tolerance level of the quality class of the sensor, otherwise the sensor/motherboard assembly must be replaced. *there are sensors that are 99-100% fault-free. those are used for scientific applications. As they cost tens of thousands of dollars, they are not suitable for use in digital cameras. 2 Link to post Share on other sites More sharing options...
