component-level repair

The most ordinary type of repair - a true "walk-in job," as repair technicians like to say. Just replace a faulty memory card slot: minimal disassembly, a bit of soldering - and the camera is saved. However, even in such a simple repair, there are a few nuances that can easily turn fatal for the camera. Our patient: Nikon D750, which, even without a memory card inserted, shows the "err" message instead of the frame counter. The camera is unusable - the shutter is locked, even if you try to

How often have you thought about the "ultrasonic sensor cleaning” technology that’s present in almost every modern camera? Probably not very often — after all, its work is barely noticeable, if not downright invisible. The idea is simple: when the camera powers off, the outer glass of the sensor filter vibrates at high frequency, shaking off dust (in theory). In practice, this technology is far from a cure-all - micro-vibrations of the glass do little against heavily charged dust, sticky

By today's standards, the Nikon D780 is supposedly hopelessly outdated (of course not!), but I've never had a chance to look inside before. This model somehow got lost between the super-popular D750 and D850, and even spare parts for it were not eagerly sold. So when I was asked about the possibility of repairing one, I replied with great enthusiasm. The problem, as described by the owner, was also unusual: one not-so-fine day, the camera simply stopped taking pictures. Pressing the shutter

The title of this post can’t possibly capture the full extent of frustration that comes with repairing modern Canon cameras. We’ve got everything here: serious damage from minor water ingress, excessive reliance on proprietary ICs, and complete unavailability of component-level spare parts. Things are so bad that if you try to Google the part number of the faulty chip, you’ll find exactly this page, plus maybe one more - also from my own site. This Canon EOS R10 arrived with a
