EOS R8 - LCD Monitor issues

AlonT — Sat, 07 Dec 2024 17:09:45 GMT

What started as a sporadic failure - now seem to be constant. Other functionalities of the camera are ok.

There are no issues with the viewfinder.The touch capabilities are also fine - but the display is corrupted.

If this is when you are trying to view images on the SD card try reformatting the SD card. While you probably have an internal failure it's free to try the suggestion.

Thank you for your reply.

It actually happens immidiatly on power on.

I've tried to format the card - no improvement.

Contact Canon for service or warranty repair, depending on camera age.

Thank you.

Pretty disappointing the R8 require service little over a year after purchase.

Each one of my previous Canon DSLRs served me for over a decade.

Welcome to the club, it seems. Have you installed firmware version 1.4.0 ? I am suspecting it as a potential cause. I would be quite surprised if it turns out to be a motherboard problem.

I have been having a very similar issue with my R8 since last week. I had turned the camera on after about three weeks of inactivity, and after about a minute the "hash screen" showed up for the first time. I've run tests and found that the hash screen can come up spontaneously after an idle period, or right after taking a shot, sometimes repeatedly. The hash screen goes away and the camera usually returns to normal function after pressing the shutter button 3 to 6 times. The problem appears to be independent of whether an SD card is installed, shutter mode (EFCS or electronic), or EF or RF lens installed. It tends to recur multiple times after shutter button "reset" described above. I have not been able to determine a pattern by which to anticipate when the glitch will occur. The camera is by no means "bricked"...however its reliability is obviously unacceptably compromised.

Hi Jeff,

Your suggestion is something I didn't think trying, mainly because even removing the battery and placing it back didn't solve the issue (though it is the only way to solve some other instabilities I've experienced).

For me the issue started when I was at an event taking short videos and saving battery by turning the camera off after each shot. That's when the issue first appeared, initially less frequent and at some point - all the time.

The camera is in a Canon service lab right now. I'm waiting for their feedback.

Thanks for your reply and additional info!

Hey, Jeff. I hate to hear you're having such a frustrating time with your camera. If you suspect your camera is acting up due to a firmware update, it's important to report the situation to our tech support team so it can be documented officially. Our engineers won't know what needs to be worked on if it isn't reported! 😊

EOS Tech support is available weekdays from 9am to pm (ET) at 800-OK-CANON (800-652-2666).

Thanks Stephen. I called TS, the rep was not aware of any such issues so I briefed him. Due to the intermittent nature of the problem I thought it best to call and describe it rather than send my camera off to them right away.

Hi AlonT,

Please update your thread when you hear back from Canon. We are interested in learning what the issue was.

Re: EOS R8 - LCD Monitor issues

AlonT — Mon, 09 Dec 2024 17:47:45 GMT

I sure will.

In my case - the issue was seen before and after the 1.4.0 FW update.

did you resolve this problem

Re: EOS R8 - LCD Monitor issues

lockwoodjd — Tue, 07 Jan 2025 15:38:32 GMT

Not yet. AlonT sent their camera to Canon and we're waiting for word from them. So I'm keeping my camera for now since it "works" at least to a degree. The bug could be either a hardware or a firmware issue. I am suspecting that the 'hash screen" has something to do with the camera's internal buffer, since it comes up with or without an SD card inserted. The surest way to trigger the bug is to run the drive at high speed, but I've had it come up a lot in single shot mode right after pressing the shutter, and if a card is installed the picture isn't recorded to it. To get rid of the hash screen I need to half-press the shutter up to a dozen times, this seems to clear the buffer but only partially. Also note the hash screen doesn't necessarily look like the picture above, it take a different form depending on the image data in the buffer; sometimes it stays still, sometimes it modulates form.

As a side note, I purchased my R8 within 3 weeks of hitting the market, so I've had it 18+ months hence warranty is expired. It will be interesting to hear what Canon says.

I have sent my R8 to the Newport News service center, if anything the problem has worsened, often requiring pulling the battery to unfreeze the unit.

The camera came back completely bricked. The care center didn't take responsibility and only suggested repair in an unreasonable price - by replacing the camera main board. I didn't take it and purchased a brand new R6 mark II from a different supplier. I'm never going back to those guys and would stay away from the R8

Re: EOS R8 - LCD Monitor issues

I accepted the repair quote. Main board was replaced, estimate and final repair cost were similar and well less than half the cost of a new or even refurbished body, which was the basis for my decision. Came back in good working order. I suspect that since I got an early production run a failure would be more likely.

Greetings,

These types of failures are uncommon, but they do happen. There is nothing inherently wrong with the R8 from a design standpoint. While unfortunate, this should not influence a future camera purchase decision. Every once in awhile electronic devices can have a defect.

Canon service and support is top notch. They really do their best . They want happy camera owners. I don't think there's any correlation between production runs. Earlier or later, defects can happen at any point when parts are being sourced from different vendors.

As far as hanging on to a 60D, I guess any camera is better than no camera, but at 15yrs old it approaching relic status. So much is improved. Mirrorless has eclipsed DSLRs by leaps and bounds. I know everyone has different standards. All I will say is there's been massive technological improvements in the last 15 years. Easily enough to warrant an upgrade.

Rick I agree with all you said. The repair cost was very reasonable (<$400) and the service rep was cordial and understanding. I even considered an R6 upgrade in lieu of repair, but the R8 has given me 18 months of solid performance. It's a keeper.
