this is amazing ! it looks very very difficult to do ! and I have disassembled quite a lot of gear

Peple do it and succeed step by step :)

before applying pressure and twisting on the front plate, make sure to pull the back part so that it will actually move when you twist.

Al final me atreví y cambié el cable. !Ha funcionado! Gracias por tu ayuda. Pude desoldar y soldar los cables del motor sin desmontarlo, poniendo una pinza de la ropa que mantuviera los muelles abiertos y utilizando un soldador super fino. Gracias de nuevo.

great that it worked out and thanks for the tipp! I post your reply in english so that others do not need to translate it again "In the end I got brave and changed the cable. !It has worked! Thanks for your help. I was able to desolder and solder the motor cables without disassembling it, using a clothespin to keep the springs open and using a super fine soldering iron. Thanks again."

Seems insane but it actually works

Muy buen día, me puede decir si ha dia de hoy 5/12/2023 sabe de algún video que explique como cambiar el cable? Muchas gracias por su tiempo y dedicación.

So I dropped my camera and the protective lens housing plate fell off. I came here to see how it goes back on and referenced your video at about 09:00 and I was struggling to put it back without disassembling the whole camera or sending off for repair. I managed to get it back on and this is how I did it … I pulled the silver triggers that close the protective doors then taped them so they stay shut. While the camera is ON I put the face plate in place and it snapped neatly closed then bc the camera is turned on the protective covers should be in open position I had to turn the plate to the RIGHT instead of left and slowly took the tape off at the same time. This snapped right into place. I hope no one has to deal with this but Good luck to anyone who reads this 🙂 thank you so much for your video!

@mikphoto Год назад

Thanks TNESL. A simple and useful tip to put the front protective plate back on the lens back again without disassembling the camera!

@tomfenn7149 Год назад

Would it not just be easier to place some tape over the shutters themselves, rather than the tiny silver levers? Thus keeping both leaf doors shut, then taking the tape off slowly once fixed back on?

@theneverendingshoppinglist Год назад

@tom fenn yes I put the tape over the lens shutters not the silver levers. I’m sorry if I wasn’t clear.

You should look my videos how to place front cover properly without these long attempts to not break it. BTW, no need to unscrew those 3 screws of front lens element to remove external plastic ring which contained lost spring. It is enough to gently rotate counterclockwise plastic ring which sits on front lens element ;)

@mikphoto 5 месяцев назад

Thanks for your Tip!

@tomfenn7149 Год назад

Thanks so much for making this video, Michael. I found that using a couple of sticky 'protect pads' (sticky dots) used to prevent cupboard doors from slamming loudly when closed, stuck to the front cover of the lens helped get a grip on the front cover to turn then remove while twisting as you say, clockwise. It took a little force but not that much before it popped off. I hope this sticky dot tip helps others who are about to attempt to fix their GR2.

@tomfenn7149 Год назад

Just want to add, I'm finding the GRII an absolute nightmare to fix. I read somewhere else that you really need to be a watchmaker to fix the inner lens capsule. Whoever said that is 100% right. The worst thing though is all the time I've invested in trying to fix my camera, could've been spent taking photos, which I'm missing. I know I shouldn't say this (because it'll likely upset the GR fanboys), but honestly, get an Olympus or Panasonic, which imho are far better built, more reliable cameras. If Ricoh had any sense they'd re-engineer the GR for the upcoming IV to include interchangeable pancake lenses. This would do away with all the dust issues and other lens/sensor nonsense associated with this frankly overpriced toy. Such a feat is quite possible, and in fact Pentax have already done it. A sign of even better things to come?

@mikphoto 11 месяцев назад

Sorry for your troubles fixing the cam. After learning about the tight conctruction I became be also reluctant to service it myself. Lucily there are photo service people who do like the task :) A shop in poland www.fotonaprawa.pl seems to do a fine job fixing GRs.

@buzhichun Год назад

After struggling with getting off the front plate, I found out it helps if you pull the internal lens element back out of the barrel a little. After I did that the front plate easily clicked loose after rotating clockwise.

@mikphoto 11 месяцев назад

Thanks fot the tip!

@pytolek 2 года назад

thank you! maybe now i can put mine together xD i felt your pain at the end

@stefanosemprini8793 Год назад

Thanks for this video!I had issues in putting back the front plate, it was not willing to trigger the door mechanism closed. I then found much easier to close the door manually beforehand and keeping it closed during the front plate reassembly with a pice of adhesive tape. By doing this way the silver mechanism is not going to catch the plastic knobs inside.

Thanks for the tape tip Stefano!

@martinaronsen3586 3 месяца назад

Would you be able to elaborate on the removing of the face plate at 1:35 min? I just cant understand this step - on my lens its impossible to turn the face plate.

@mikphoto 3 месяца назад

Sure, what is not clear? Do you have a GR II or III? The model I used in the demo was the GR II. The comment from @buzhichun mentioned it helped him to pull the internal lens elements back a little and then turn it as described.

@mo_boh Год назад

i managed to take apart everything, but sadly i also broke of one of the front plate parts, so it doesnt hold in place properly now. sadly, it turns out the pcb wasnt the problem, so it was all for nothing and i still dont know why it wont turn on :(

@tomfenn7149 Год назад

@mobo4133, get yourself a multimeter with a continuity tester built in. Sometimes PCB's can look undamaged to the naked eye, but their may still be a fracture on the pcb you cannot see. And disruption to the bleeping of the continuity tester will confirm a break in the copper.

@tomfenn7149 Год назад

Update: I now have more empathy for your pain! 😂

@aloysiuspuspandono1833 2 года назад

hello very nice explanation! very helpfull.. are you making the video how to change the that flex ribbon cable?

@mikphoto 2 года назад

Yes I plan but did not decided when to do it. One problem is that my GR is in bits (some more cables defect). Even when I change it there would be no way of confirming that it was the fix.

@tomfenn7149 Год назад

@@mikphoto I can understand fully why you haven't. These cameras are a nightmare to fix, and I completely understand now why many professional repairers won't even entertain the idea of fixing them. I may have to go back to using my old (and slow) GRD4, and concentrate mostly on using my Olympus OMD seeing the latter is far more reliable and faster than the Ricoh's. But that said it would still be nice if someone somewhere would explain how to go about replacing the bad cable, just so I could entertain the idea that I may not necessarily have a £500 useless door stop sitting around on my desk!

@@tomfenn7149 you´re in luck! Follow the steps and links: michaelkowalczyk.eu/library/howtos/howto-repair-ricoh-gr-closed-shutter-broken-flex-cable/

@tomfenn7149 Год назад

@@mikphoto YES!!! Earlier today I was ready to throw in the towel and give up on the thing. It’s so delicate in there and I was so afraid of causing permanent damage. I’ve also got a GRD IV, and that works like charm still. So not all lost. However the card write speeds on the IV are painfully slow.

@tomfenn7149 Год назад

Ahh. Should’ve read before posting. I’ve already seen this, and studied it very carefully. I just can’t figure out how to reliably detach the motor servo for the shutter from the lens capsule. I’m sure there is a way, but sadly I haven’t quite discovered that yet.
