Well I guess it's finally my turn to have a sensor issue, at least I think that's what it is. It's in every photo now. It wasn't there and then it was.
I hadn't changed any of the camera settings. It might have gotten pretty warm on the last use when it first showed up.
Blown pixels all the way up and down the image in a perfect column? It's in the same place in every image. Is the only answer to send to Canon repair? Anyone else have an issue like this? I bought the camera as new here on the buy and sell forum and it's had very little use since...
Any idea of cost since I'm not the original owner and don't have a receipt? The fellow I bought it from said he didn't have a receipt when I bought it?

Have you tried different memory cards and card readers to rule out those as the cause of the issue?
I tried two other cards, one SD and one CF - it's still there and now it looks like it's two columns. I tried a different card reader and it's still there. I can see it when I review the image in the camera magnified through the viewfinder....blah me.
Dang.
That doesn't look like blown pixels to me. It looks like the sensor took a hit or was somehow damaged in the bright dot area that destroyed the entire vertical row.
Have you done any nightclub or concert shooting where perhaps it got hit by a laser?
Either way, it looks like you're going to have to have it replaced. Hopefully it won't cost a ridiculous amount. Good luck and let us know how you make out.
Very strange in appearance once zoomed in. It looks different in the light areas vs dark areas.
I had an issue like this with a 1DIII back in ~2008. It was a one-pixel wide vertical white line that recurred in all images in exactly the same location. While it was visible in all images, it became more apparent as the ISO value increased. I believe the ultimate fix was replacing the sensor. Before that Canon replaced the main board containing the processor, etc., but that didn't fix it. In my case the defect did not have a bright spot and the line was unbroken/continuous. Until it was fixed, my work around was a Photoshop action that selected one half of the image exactly beside the line, created a layer and shifted the layer one pixel to cover the line. It was generally an acceptable solution but obviously was not a perfect one because on occasion one could see the hard edge of the shifted image area in certain situations.
I do think the only solution will be servicing by Canon and I'd guess a likely sensor replacement. The last time I had Canon quote sensor replacement for out of warranty equipment, it was in the CA $1500 range. But that was a long time ago and a non IBIS type of sensor.
I was shooting surfing back in the day and all of a sudden I noticed green lines across the frame. The green horizontal lines were random in location and intensity, and the number of them varied depending on the ISO level of the scene as the photos show below. Took a few test shots of different things on the beach and a plane flying over and here's what it looked like. Turned out if was a bad sensor on one of my 1DmkIV's. Canon replaced it free of charge out of warranty but probably because I had been regular there for many years. Your R5II is brand new under warranty so if they don't replace the part they should just replace the whole body.

I do think there's a good chance they will take care of her even without a receipt, but she doesn't have the luxury of walking it into Canon like I can since I live so close to them.
If they shoot her down I would suggest signing up for a CPS account and attempt to get it done through them.
This guy seems to have a decent amount of feedback so I would think he'd be able to track down a receipt, or request one from whomever he bought it from:
In the past, Canon has serviced/repaired equipment for me that I did not have a receipt for, as long as the date code was within the warranty period. Apparently, Canon can tell the date of manufacture based on the R5 Mark II's serial number, so you may still be covered for this repair, but you'll probably have to send it to Canon to find out.
I haven't ever used the camera in a night club period let alone one that had a laser. I've never dropped it, never had it wet, no corroded batteries either. On the side of the original R5 box there is a sticker from where it was purchased with their name, Fort Worth Camera LLC and maybe their inventory number. I included a picture of that with the packing slip to see if it would help? I asked the fellow here I bought it from for the receipt when I first bought it - he said he didn't have one. I asked how he bought it without one and I didn't get a reply. That was through texting I believe. I just sent him a PM asking again for a receipt copy.
I'm not very hopeful that it will be a warranty repair. The paperwork instructions to send in for repair has the information below in bright red:
2. If this is an In-Warranty repair, proof of purchase must be provided. If you have already uploaded your proof of purchase, you have satisfied this requirement. If not, please enclose a copy of your proof of purchase in the box with the packing slip on page 4. Please note that without this information your repair may be delayed and you may incur repair charges.
I'd contact the camera store and see if they can help you if the seller won't. Maybe they can 'reissue' the receipt in your name? I agree it's strange that the seller wouldn't be able to provide the receipt. If he bought it from the store, they should be able to reprint it for him. Unless they are really old-school and still do handwritten receipts, but even then they should have a copy on file in case of an audit.
If the seller ghosts you, it's definitely a legit reason IMO to derate him, if that's possible, on the B&S.

To our OP:
I’m thinking that the laser theory is extremely unlikely since the problem pixels all seem to be in the same physical column on the image. Aligning a laser that perfectly during a performance, especially while hand-holding the camera is not impossible, but it is about as close to impossible as you can get and not be there.
I think this also makes physical damage (for example by something striking the sensor surface) equally unlikely.
My bet is that this is a sensor issue, though that could include some kind of issue with the connections to the sensor in the camera. It is weird that it skips over pixels though — when I’ve seen stuff like that it is usually a whole row or half of a whole row.
Also, when I’ve seen issues caused by bad cards (or bad connections to cards) they have looked a whole lot different than this — often multiple horizontal lines (not vertical) and with odd patterns.
In any case, that camera is either going back to the seller (assuming that it arrived with this issue) or to Canon for warranty service. I would at least contact the seller and have a conversation about it — though if you have had the camera for a while without noticing it (even if because you did not use the camera much) it may be too late to say/do much about it.
Dan, I think it's one extremely hot pixel that is somehow overloading the column and resulting in an artifact that appears as a vertical line, but I have no scientific way to explain it.
The sensor is read out in rows so something is causing it to 'glitch' at the same point along the horizontal run as the rows are read out. Maybe @snapsy or Jim Kasson could provide a correct explanation. But it would only explain why and be of no benefit to the OP with their dealings with Canon.

Any reputable seller here is going to try and help the OP out by going back to the store and getting her a receipt. This should not be considered an unreasonable request since his ad said it came with "paperwork":
Item 1: R5 ii
For sale is a brand new condition canon r5 ii US model with paper works, 0 shutter count, only opened once to check
He should be able to go to the store or call them up and have a receipt emailed to you. If this is not possible then something seems fishy, and I agree with rscheffler you should change your feedback if he doesn't offer to help. This will help all of us to avoid buying from him in the future.

I know what the standard legal boilerplate says, I just thought it was worth mentioning that the service centres do have some leeway in what they will cover, especially if it's obvious the camera is less than a year old. What do you have to lose by asking?
I really don’t think a camera store (Fort Worth Camera) would look up a receipt by serial number or inventory number, if that’s what that is on their sticker on the box, and give a copy of it to someone whose name isn’t on the receipt? Right
Response to my PM asking about getting a copy of the receipt:
“Hi I’m sorry to hear that happened, but I don’t have the receipt for it. I buy and resell gear, this one didn’t come with a receipt.”
