- Cap replacement on Minolta X700 didn't work? If Minolta parts didn't get the camera to release here is a repair tip I have been doing since the 80's. Every once and a while after replacing the caps and cleaning up the circuit boards the camera still doesn't release consistently, follow the video.
Wow. I had this exact issue. Camera was turning on, and the light meter worked fine, but the shutter just wouldn’t fire. This was my first EVER soldering job! I replaced the bottom capacitor-which definitely needed to be changed anyway-to no avail. Gave this yellow wire trick a shot and it miraculously worked! Camera fires like new now. Thanks!
Hey Jim! Thanks for the awesome videos! I'm working on one of these right now. I've replaced both capacitors, but the light meter doesn't read correctly, bottomed out even pointing at the sun. In program mode, light meter displays between 2 and 4. Any ideas what could be wrong with it?
Nice repair! Quick and easy!
Hi, I replaced the bottom cap, and did the yellow wire mod you showed here, but the the shutter still won't fire, and won't rewind. Any ideas? There's some videos that talk about another cap on the top side. The X-700 is a great camera, and I'd hate to relegate to the landfill. Thanks!
I had the same issue. Well, removing the corrosion does actually help, I was quite surprised that corrosion that was barely even visible caused the problem.
Thanks, I found your explanation in the comments and that really helped. I absolutely did not expect that corrosion could cause such a voltage drop.
Hey I'm facing an issue where the shutter won't fire and the film advance lever is stuck. Do you mind giving any tips that'll fix this problem? Thankss
@@prollyharry781 If the meter is still working it is probably the two capacitors (the non tantalum ones) or maybe corosion on the bottom cicuit board. In my case it was both. btw the older X 700 usualy do not have that issue, because they build entirely with tantalum capacitors which are way more reliable. There should be information in the web how to change them, which might be to much for just a youtube comment.
Thanks for the tips! What soldering iron are you using for this job?
I use Hakko soldering irons.
Hi, do you have any trick for the minolta x300s? I have the same problem. Thank you and nice video ✌️
hi! after connecting the yellow wires, do the excerpts all work?
Hello, I have a small issue with my Minolta x700. The speed displayed in the viewfinder is always very low in "Aperture priority" or "manual" mode. However, if I switch to "program mode" without placing the zoom in the "program mode" notch, the displayed speed is higher and seems more consistent. I admit to being a bit confused. Thanks for your help.
Ps: I love your videos!
My first camera!
Nice, but what's the explanation? Current goes where it doesn't belong or a minimum amount of resistance through the board?
I think the corrosion make a resistive pathway on the board and pull the voltage down on the yellow wire. I think but cannot prove it. All i know is that it works.
@@ictcamera560 I'm curious how did discover it
@@d5husky I had it on my desk for two hours troubleshooting the electronics. I knew it yellow wire needed 2.3v or more to release and when at rest it was testing 2.7v but when I went to release the voltage would dip to below 2v (1.9v if I remember correctly) and the camera did nothing. At that point I lifted the wires to run down the short and by lifting the wires it worked. Many times if you lift the diode on the board you will see corrosion underneath. So I think the damage from the capacitors causes a short to happen but it is only a theory.
and last question, everyone says there are two capacitors, but on top there are two of those, right? I saw another guy replace both on top plus the bottom one. I’ll try to replace it once I buy a better soldering station
@@d5husky On the X700 there is one on top and one on the bottom, some other Minoltas have two on the top and one on the bottom.
WOW IT WORKS !!!!
Great video ITCCamera… thank you for the tip, however, if you know any hacks for the x700 Minolta for when you advance the film and the shutter fires automatically. I don’t have any play in the fire button which leads me to believe(a light bulb just came on in my head) that the button is stuck. I hope you have a fix for this because I tried the method in this video and that didn’t fix my issue… many thanks in advance if so!!!
Jim can you do this with the xg7?
Thanks
You've done this in a lot of cameras? I'm new to fixing cameras and don't want to break it even more
Update: it doesn't seem to work. The shutter was working yesterday, gave it a few clicks, then today stopped working and I can't seem to find the problem. The capacitors are just like these on the video, the battery is new, it turns on and beeps but doesn't fire
@@henriquerennourbanavicius7113 same problem here
@@medasvaiseta6026 ok, try to spin the motor drive on the bottom a little bit, this will make the shutter fire. If it does help, reply again and we'll see what to do next. I fixed mine las week
Great! Can you please, show us same trick for Minolta X-570/(X-500) ?
Even though the 570 and x-700 are in the same family of cameras they are not the same and it does not work.
@@ictcamera560Yes, I know and that's why I asked you to show us the same for the X-570 (
If it's possible).
you are a genius!!!
is there any function that wont work aftert this hack?
This is for release problems, if there are other issues with the camera those will have to be dealt with separately. Please note; this can fix many cameras release but not all.
Didn't work for me :/
what are you by-passing ?
The board which may have a resistance now because of the leaky cap.
Neat trick!
Great job !
That's excellent. I wonder why they ran it through the board when those wires were so close anyway.
So, it’s been a year. Do you have any plans to post new videos? It looks like your eBay store no longer exists.
Thank You for that information, I did remove my eBay store for a while but reinstated another not to long ago. I will take a look to see what is going on. Try ICTstore on eBay
hey quick question whenever i turn my x700 on the beeping from the light meter wont stop even if im not pressing the shutter. can anyone help?
This is amazing I replace both capacitors. What a bitch on the top one and all I really had to do was this thank you. I really appreciate you putting this out there. You have no idea how much of a help it is.
I have the same problem but on an XD7 will this work with it?
The XD series is a completely different beast and nothing except batteries and film interchange.
@@ictcamera560 thanks I was reading the camera manual and the wires sealed to be s1 connection this assuming it could work. Two large paper weights at the moment. I actually have an x700 where the film winding doesn't fully move to the next frame leading to some double exposures. It works well with the motor drive though. What would your thoughts be on this
Thank you Jim!
This is very helpful but I have now another problem so I changed bottom and top capacitor under film sensitivity board and now only aperture release mechanism reacts. The shutter still doesn't work. Each time I need to do shutter release procedure by connecting 3v on ground and green wire. Any ideas what to do next? drive.google.com/file/d/11_Qiao-HM_dMJonDy3YgtVEHhW7K7cfl/view?usp=share_link
