tele_player Posted August 14, 2021 Share #1 Posted August 14, 2021 Advertisement (gone after registration) I recently received my M9 from Kolari Vision, with sensor rendered completely dead by Kolari Vision's attempt to replace the cover glass.

Casey Jefferson Posted August 14, 2021 Share #3 Posted August 14, 2021 The Chinese are very confident with their works. I recalled they already started doing the replacement since 2016. They repair all sorts of camera including the M10P SD error, ISO dial malfunctioning etc, and plenty of complex zoom lenses that are submerged in sea water. They shown M9's with contact pins corrosions but never show they actually repair those, though. Link to post Share on other sites More sharing options...

What did they say ? did they acknowledge that the cover glass replacement has failed ?

tele_player Posted September 5, 2021 Author Share #5 Posted September 5, 2021 Yes, Kolari Vision told me that the sensor failed testing, then they returned the camera, and refunded the $1000. The camera now just produces a black image. 1 Link to post Share on other sites More sharing options...

How much does the Chinese shop charge for M9 sensor glass replacement? is there a contact or website? the video is very impressive.

Marac Posted February 25, 2022 Share #8 Posted February 25, 2022 Hopefully I will have good news next week as my M9 will be returned, repaired, right here in the UK. The fee is around £1000 (this still needs confirmation) So I guess anyone in UK or Europe should be looking at ACS as an option. Advanced Camera Services Norfolk UK Welcome, dear visitor!

Marac Posted March 15, 2022 Share #9 Posted March 15, 2022 Camera back from ACS, they matched the RF to the only lens I sent, Voigtlander Nokton f1.2. They are all jpg (didn't realise until after I got home) The RF is not set up properly yet as their main concern was about how the filter looked & rendered, please let me know what you think. I will get out and take some more in RAW when I get the chance. Welcome, dear visitor!

Thanks for this Marac, I'm interested in your experience as I'm presently sitting with an M9 brick due to the 2nd replacement sensor having corroded. It's difficult to come to any conclusions based on Jpegs e.g. looking at your images I detect a bluish tinge, that's probably a Jpeg processing function which I'm sure can be corrected in PP. Overall how does the image quality & sharpness look to you? Look forward to seeing some of you DNG conversions.

jankap Posted March 16, 2022 Share #11 Posted March 16, 2022 There are no two half pictures visible, the main trouble. The repair seems to be ok. Link to post Share on other sites More sharing options...
boojum Posted March 17, 2022 Share #12 Posted March 17, 2022 If you did not have an IR/UV filter on the lens and did not focus the camera I would suggest that you have some problems on your hands. The M9's are a lovely camera with the CCD sensor. CMOS is approaching the CCD quality and can be made to look almost as good but despite the efforts at jumping through hoops in one shop I still think the CCD has richer colors. That's my opinion, YMMV. With enough work I suppose almost any sensor can be made to look almost as good as the M9 CCD. That is not the point. The image as it comes out of the camera is. We have a fellow here in the Pacific Northwest, Jadon, whose has been doing repairs of the corroded M9 sensors. He has worked on my M9 for other work and was a competent and thorough technician. I cannot speak for his sensor repairs. I would take my M9 to him for sensor work. What results have others had with his sensor repairs? Link to post Share on other sites More sharing options...

Jrek Posted April 9, 2022 Share #14 Posted April 9, 2022 (edited) Reporting succesfull sensor glass replacement. I followed the well known chinese videos which show how they get it done, managed to source the same glass they use and tried to do it myself. You need sharp scalpel blade, very steady hands and lots of patience to remove the epoxy/glue or whatever they used to fix the glass, but it can be done. I've used Araldite solvent free epoxy to affix the glass to the sensor. Sensor works fine and camera focuses correctly. Colours seem to be ok to. I will do some more precise focusing tests later today or tomorrow and will come back with results but for now it looks like I've fixed my slowy corroding sensor and saved some money on the repair.

Raymondl Posted April 11, 2022 Share #17 Posted April 11, 2022 @Jrek that’s incredibly impressive ! Good on you for doing it yourself. What’s your technical experience ? I am assuming this is not your first time opening / fixing an electrical device. Also how long did it approximately take ? Just curious, more than anything !

I have some experience with small electronic devices but as a hobby, not professional, and I opened non working Leica M9 before to have a look inside. It took me about 3-4 hours from start to finish, only because I was very, very slow and carefull when removing the glass.

Could you point me in the right direction for where you sourced the glass and what youtube videos you followed, or any other tips Cheers! Link to post Share on other sites More sharing options...
