Weird black stripes on photo with light

[Andrea86]

Good evening and pleased to meet you, I have a strange issue on an camera on sales that only some specialized forum can solve. 

The camera is an Sony a7 ii, Seller tells that during photo on high level of light, some weird horizontal/vertical stripes appears on photo. 

I know that some purple horizontal stripes on pictures can be caused by bad sd data transmission, but I never saw something like that in picture.  

I have an wonderful a7sii and I never had that issues so I can't value if it's an opportunity to buy or an big mistake. 

Almost forgot, the camera has around 56k shoot

here you are a bigger pisture that show the issue. 

Pdaf? bad sdcard communication? damaged sensor?

i really cannot figure out what should be. anyone had faced this problem before?

They should try to remap the sensor, it's in the toolbox menu, at least on newer cameras, not sure about the A7 II but it should be there.

If you're considering this camera to purchase, I would run away. I wouldn't buy that camera no matter how cheap it is.

Even to use it as second camera? You think should be an sensor issue? 

I read around on internet that could be also some issue of corrupted sd cards or bad compatibility with some lens. 

I'm really not sure that could be true, that's why I would like to have much point of view as possible. 

The camera could be sell around a hundred bucks, but I can afford the operation of changing some internal part eventually, but definitely not worth an sensor replacement operation, especially for an second camera. 

I think that if the issue is manageable without changing the sensor could be an big opportunity for having a second camera for almost nothing, otherwise I think it should be an loose of time and money 

Hope I get the point, English is not my native language 

Thanks in advance for everyone would gave me their point of view

Don't worry, I can understand you just fine!

Could be anything. An SD card shouldn't be too hard to check. If you can get the camera that inexpensively it may be worth a shot, but the sensor and/or processor scares me. If you can't find out what's causing it through simple processes, then I would proceed with caution. 

Question: You say it shows up on the photo. Does it show up on the rear screen before the photo is taken? And, does it show up in the viewfinder? 

[Andrea86]

Asked today. He confirmed that the problem is present also during picture shooting and in the viewfinder. 

At this time, I wouldn't risk to buy it, but I would like to say thank you to you, for your support and idea. 

I will keep shooting with my beloved a7sii!

I think you made a wise decision. Don't worry, the right 'next' camera will come along!

Would consider buying a used camera from a reputable seller who has checked the camera out and offers a warranty and has a good return policy. Good example is mpb.com

Typo

I'm betting this was the result of shooting silently under LED lighting.  If the mechanical shutter is used I believe it will not have this banding.
