Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

I suspect the screen or LCD screen itself, is what has gone bad.

Does your camera have a smaller screen higher up? if so, that's a viewfinder. What does it do?

How old is the camera? in months or years since you bought it.

Has the camera been dropped or otherwise subjected to mechanical shock(s) in its lifetime?

Has the camera been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?

Has it ever been subjected to a humidity higher than 85 % or gotten wet ?

Has the camera been operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?

Hi,viewfinder works fine, I can see the settings on it and can change these settings. Camera is 5 years old, but was used very lightly. It was working fine and got broke only after I disassembled the it (to get rid of small piece of plastic that broke off the body and fell inside). After I assembled the camera, screen was no longer working. I tried to power it on before I fully assembled it, so this might have played its role.
Expert:  Russell H. replied 2 months ago.

Then, given that it was disassembled, you may have not quite placed back properly, a delicate cable (called a 'ribbon cable' because it looks like ribbon) going to the main LCD screen. Or may have dislodged it ever-so-slightly.

You will need to disassemble it again, and carefully seat the ribbon cable to the LCD screen properly this time, and without pulling it loose while putting the case back on.

(And no, if the screen was working when you powered it up before reassembling it, then that *didn't* cause the problem, at all... in fact, it was rather good-enough procedure.)

Let me know if that answers your question in full, or if you need more advice instead.

Customer: replied 2 months ago.
I tried reconnecting ribbon cable a few times, it did not help.
When I powered the camera on the screen did not turn on. Back then I did not know how to handle zif cables, so I broke one of them.. and it resulted in buttons not working, which is now fixed. Ribbon cable that goes to the LCD looks fine (undamaged)I also checked power board for blown fuses - all fuzes are fine (show zero ohms), so I am a bit lost at this point
Expert:  Russell H. replied 2 months ago.

Then it may simply be in a state of shock - esp. if (perhaps) you did not observe sufficient anti-static precautions while handling components with the camera opened.

I'd say, close it up, remove the battery, wait with it like that overnight, put the battery back in, and see whether that (rest and reset) gets it working again. It might.

it was powered off for a while (while I was waiting for new ribbon cable to be delivered), it did not just start working after I powered up...
Expert:  Russell H. replied 2 months ago.

Then it may just have to be sent to a repair facility, or to other than Canon, for repairs.

Let me know if you would like an estimate on non-Canon repair... I can provide one.

Customer: replied 2 months ago.
I'd rather fix it myself. I am suspecting the other zif cable that I was struggling with and which does not look like it is damaged. Do you know how I can look-up its part number and where I can order it?
Expert:  Russell H. replied 2 months ago.

I have no idea, frankly. Such knowledge is usually held proprietary by Canon, regrettably.

A camera shop might be able to provide either piece of info, though if they only provide the part # to you, I could try to find a source by the part #.

Can you see a part # on it? or anything that might be one?

Customer: replied 2 months ago.
here is what's written on it: "CH1-8607-030 TFT-M", but I could not find where I can buy it
Expert:  Russell H. replied 2 months ago.

It is late (in my time zone) and it would be advisable for me to quit and try to find that tomorrow morning, with my full faculties in order. Is that OK?

(That does sound like a part #.)

Customer: replied 2 months ago.
sure, thanks for your time
Expert:  Russell H. replied 2 months ago.

I cannot find information on that part #, I'm sorry to have to report.

Is it possibly attached permanently at one end? if so, to what part? (I don't need a part # for that other part, just a vague identification... if this is actually how it is, that the cable is not an independent part.)

Customer: replied 2 months ago.
The cable is an independent part, I found the list of parts for 5D mark II online and found the part number: CG2-2290-000 (FPC ASS'Y, TFT-D CONNECT). I ordered it and will replace the cable as soon as it will arrive, hopefully that will resolve the issue.
Expert:  Russell H. replied 2 months ago.

But what you have is a TFT-M... are you sure it isn't the wrong part # for this part? I'm concerned lest there be a mistake, perhaps.

Customer: replied 2 months ago.
whoops, I did not notice this difference... Cable looks exactly as it is in my camera (not from up close though - no chance to compare them this way yet). Perhaps TFT D means TFT Display and TFT M means TFT Monitor, which is the came thing.. hopefully.. I will have to install it and see if it will work. There are a lot of search results in google for TFT D and next to none for TFT D, so perhaps it is a TFT D cable, even though TFT M is written on it.. I will find out for sure soon
Expert:  Russell H. replied 2 months ago.

OK. But I would be cautious about expectations.
