Simply a super guide for 60D. I've got a dead 60Da. No display or anything. I think everything will be the same inside. But this series gave me the courage and precise guidance to open it up and search for faults. Thank you so much Robert👍😊
You're welcome! Good luck on your 60Da repair.
We had a 60D that just stopped working out of the blue. One day it was fine the next one I tried to power it on and nothing happened. At first I thought it was a dead battery but nothing. We tried a different battery - still nothing. I tried all the reset methods and latch checks and what not - nothing helped. We left it with a repairman that said it's probably the board - not sure if he even opened it.
It is beyond me how a working camera with no more than 60K clicks could just up and die. And whenever I circle back to this video I get the urge to somehow fix it lol. Any explanation on what might have killed it?
You're right that 60K clicks is not much. My first thought would be that the power board is bad. It's not uncommon for that board to go out. And if it's not that board, then I would suspect that the main board is defective. If you're interested in fixing it yourself, you can search for parts on eBay. There are quite a few sellers on there that sell individual 60D parts.Unfortunately though, both the power board and the main board can be a bit spendy. Sorry I can't be more help.
Thank you so much Robert! Just finished watching your 60D series of videos and found them clear, concise and easy to follow. The video was always bright and sharp and the audio commentary easy to understand.
I have canon 70D body not powering on. Symptoms are
1. Showing only low battery symbol in case of battery low . I battery is charged then no sign in Top LCD or anywhere.
2. As soon as battery is placed and close the door, i notice the top LCD display flicker with orange light and nothing happens
3. i checked SD card & Battery door sensor. both seems to be good.
I'm not familiar with the 70D, but what you are describing could possibly be a bad power board if it were doing that same thing on a 60D.
@@Thebobfactor Thanks Robert. I well check the power supply
hi, mr Robert, in my 60d, first error 70, after clean connector all around the circuits, not power up, again, re check all connection, error 20 coming up, after try deferents times it coming out , no power again, i follow you and check power boar, read wire 8.4 v, which is good, orange wire , give me 4.7 v, but directly, i mind, i didn't touch any botton around,,just get the voltage always in orange wire,,,,this situation means something for you,,,thanks.
Hey! Awesome videos!
I have replaced the shutter unit in my 60D (that was the only problem), but can't get the camera to power on AT ALL... :(
I did some of these test - but one reading is off - the red wire in the top connector (minute 5:20 in the video) - it is always at around 5v - doesn't matter if I press any button or not...
Please help!
And thanks alot for the awesome videos!
Cool. Glad you like the videos! On the LCD display on the top, are you getting a blinking battery indicator at all?
Nope, unfortunately - nothing :(
I made sure the batter door switch is pressed and the SD card switch also...
When you are trying to power up the camera, do you have the main back cover on? There is a micro switch that prevents the camera from powering up if the back cover is off. You can see the switch here: ruclips.net/video/yeCrpv_u1Zw/видео.html.
Robert Hosea yep, I stuffed a piece of paper there... 😮
Any other ideas? Maybe a power cable I forgot to connect?
I’m afraid to disassemble the board again because the screws are not 100% and I might strip some of them accidentally 😖
Rats. I was hoping for a simple fix with the micro switch. But I'm afraid the next step then is to remove the boards and check to make sure that all flat ribbon cables and wires are connected. Double check the flat ribbon that comes off of the top piece first, since it is the one that is coming from the power switch control.
I was told the DC-DC board of my 80D needs replacement. The 60D & 80D are quite similar and the board doesn't require a major disassembly. Do you think I could manage it following your 60D video?
Sorry, I haven't worked on an 80D yet, so I'm not sure how similar they are on the inside.
Hello.. my 60D got wet. Now no matter which lens I attach it gives me intermittent ER01 (cannot communicate with lens). I Opened it up to clean off some of the grit on the bottom board. But maybe I'm looking in the wrong place
Hi Israel. If it got wet enough on the inside get the circuit boards wet, then you may have to thoroughly dry the boards by removing them and then air drying them. Even the smallest amount of moisture on a circuit board (either side) can cause a problem with it. I would dry all of them just to be safe.
Hi Robert, is it possible the board fried during a repair even if the battery was out the whole time?
Hi Jenelle. I could only see that happening if the one of the circuits on one of the circuit boards somehow came in contact with the flash capacitor while it was still holding a charge. That could definitely cause some damage. I have seen the power board get fried when the battery was put back in and then the camera turned on, when one of the flat ribbon cables had been put back in wrong and it ended up underneath the bottom board, and then one of the screws went through it and shorted it out. Is anything at all showing up on the upper LCD display?
Hi Robert, I'm watching your videos to try to find out what is wrong with my camera. The only different measurement I had was at the point where the voltage should vary when pressing the shutter button. I always have 0 volts there. My camera doesn't turn on when I put the battery in it. I just have an empty battery symbol flashing on the display. Do you know what could be the problem? Thanks in advance!
Hi Patrick. It sounds like it may be a defective power board. There was one time where a flat ribbon cable that wasn't fully inserted into it's socket caused a similar problem, so it may be worth checking the flat ribbon connections (if you haven't already). Other then that I would guess that it's probably the power board that's bad.
@@Thebobfactor I checked the cables and everything was good. I will try a new power board! Thanks for the reply!
Hi Robert! As a tinkerer myself, I wanted to come to you with a problem I have with a 60D. It will not turn on. The first thing I did was try every permutation of the “Take Battery, Card, Lens off, Put on P, Hold shutter down for a while” Trick. But that has not worked. I figured, well for this trick to work it must mean the camera has an internal battery. I also figured that it must be pretty easy to replace - as it was probably a simple watch battery.
Turns out, as I read in a forum, the internal battery is not easily replaceable. It’s part of the board or something. I am still in the process of watching a lot of teardown videos, and I’m waiting for when someone gets to the internal battery, but I figured I’d comment first. I’m planing to disassemble it and see if I can fix it, but any guidance/theories you have would be much appreciated. Thank you for your helpful videos!
Apparently, the previous owner tried the reset trick, and did say that the LCD lit up for a second. But any consecutive attempt does not replicate this result. As i said, my guess is that that internal battery has not enough charge left to make the reset. This camera has been in storage without a battery in it for at least 5 years, so I really think that is the reason. Looking forward to hearing from you!
I have heard that the camera will not start if the little internal battery is dead, but I could never prove it. I had one camera where I replaced the battery with another (same voltage but different size) just to see if the dead camera would come to life, but it didn't help at all. In the end it was a bad power board. Of course, every situation is different, so I would be very appreciative to hear if replacing the battery does help you out in your case. Good luck with it!
@@Thebobfactor Thank you so much for your response! When I get a chance I’m planning to watch the rest of your videos in this 60D teardown series, but if you know offhand which of these videos, and at what timestamp, you locate and show the internal battery - if you do show it? Thanks for your optimism. We’ll see. If it is a bad board, is there anything I can do about it or is it just a paperweight at that point?
@@DiCasaFilm, unfortunately I never did include the battery location in any of the videos. If the power board is bad, it can still be worth replacing it if the rest of the camera is in good shape. When I was using my 60D a lot, and having to repair it a lot, I would find a broken 60D on ebay to buy for repair parts. I would look for one where the seller lists exactly what the problem is with the camera, such as a broken LCD, or that it's reporting a shutter error code. That way I would know that the power board or main board or whatever I was needing was still good. It's a little more of an investment that way, but I almost always used many more parts from it for other repairs too. Lol. I'd sure be interested to hear how you make out on your camera.
@@Thebobfactor Once again. thank you for responding. Very good info to know. Do you know where the battery is in general, even if you didn’t show it? Wanna know what I’m looking for. After this question, I think I’m done bothering you. haha. :)
@@DiCasaFilm You're not bothering me one bit. I will need to see if I have a 60D main board somewhere, and try to locate it on there. It might take a day or two before I can get the board to look at though.
Excellent video!
By chance are you also familiar with the 70d? I'm troubleshooting a no-turn-on issue with mine. After tooling with the microswitches, which all appear to be functioning correctly, I came across your video and opened up my 70d to check out the power board. I'm reading 8V as expected at the solder joints on top of the board, which you pointed out are the battery contacts. Where you have an orange-black-red lead going to the bottom board, I have a red-black-orange lead. I read 7.6V on red and 4.2V on orange, regardless of whether the power switch is on or off. Also I get nothing on the LCD. Sounds wonky to me, what do you think?
Hi Ryan. No I haven't worked on a 70D at all. The two readings you got could be correct, as they are close to the 60D readings. But without knowing the circuit it's hard to say for sure. If the camera's circuit is similar to a 60D, then the readings may indicate a problem with either the main board, or the top piece. Is anything displayed on the top LCD at all?
Robert Hosea thanks for writing back! This camera never shows any signs of life whatsoever, no LEDs or LCDs turn on in any states. Battery confirmed good on another camera.
Although the microswitches look mechanically intact, I might trace the leads and check voltage. Do you happen to know what voltages to expect on the microswitches when they’re open? I imagine it’s pulled up to TTL on one side and ground on the other, ie the switch grounds some input pin, or vise versa. Does the power board supply TTL level voltages that can be probed? Also, do you know if the power board outputs 4V on the orange lead to the bottom board if one of the microswitches is open?
Interesting point regarding potential problem with the top board; the 4V reading is similar to what you reported when the shutter release or other button is held down. Could be a shorted button or maybe an open pull up/down resistor somewhere. I semi tested this theory with my other camera, a working 60D; held down top panel buttons as I turned on the camera. I was hoping that the camera would not turn on since that might confirm the broken button theory, but it turned on just fine.
Are you aware of any fuses in the system?
Another avenue may be the master power switch.
Ryan, I've never checked the voltages on the limit switches, but since we don't know if there is a problem yet with the power source, comparing the voltages may not be 100% accurate anyway. If you can trace the wires for the switches it would be much better to test for continuity on them while activating/deactivating them.
I would think that the 4.75 volts on the 60D is TTl logic voltage, since it's approx 50% of the source.
Supposedly there is a fuseable micro SM resistor on the power board for a 60D, but I've never located it.
The main power switch could be bad. If it's similar at all to a 60D's it should be easy enough to test it, since there was just a few contacts and brushes associated with it.
My 60d after 3 years in Kenya stop working. only battery flashing on lcd. Need check power board with meter too. Thanks for video.
Let me know what you find when you take the voltage readings with the meter if you can. Good luck with it. Thanks!
Robert Hosea Good morning. I open body my 60D, it's unreal..., can i send to you some photos of boards and other items? But email correct on site www..?
Good morning. Yes, you can send the photos to youtube@thebobfactor.com.
Hi
Hey Robert, I Have a 60D that gives a blinking battery icon irregardless of what battery I put on it, even when the camera is off. I'm wondering if you've stumbled across that and if it's either the Power Board or the Logic board.
Hi Eric. I have run into that problem two times. On one camera it was from the power board being bad. On a different camera the problem only appeared after I had disassembled & reassembled the camera in order to put in a new shutter assembly. It took me a while to figure out what the heck I had done to cause it to do that. It turns out that I had simply replaced one of the flat ribbon cables backwards. And I believe it's the only one that you could do that to. Here's the spot in the second video in this series that shows that particular flat ribbon cable, which goes between the bottom board and the main board: ruclips.net/video/_-gQbCM7QMw/видео.html . So, if the problem only showed up after you removed that flat ribbon cable, then possibly that is the same problem. -Bob
@@Thebobfactor Thanks
Robert for the fast response. I had this issue then I took it apart to get some readings. So the ribbon cable seems ok. I might just replace the power board since it's not that expensive and we'll see how it goes.
@@airslashfury @Robert Hosea I got the same problem with my Canon 60D - blinking battery icon. Were you able to fix it?
@@devindamolligoda9691 Yes, just replaced the power board. Cheap and simple!!
@@airslashfury Thanks for letting me know. I will open up mine and check.
