    Posted: 10 April 2021 at 20:31
I’ve just acquired an A7R and lens on eBay described as being “...in mint condition with the boxes and all accessories”. I received it yesterday and indeed they both seem in good shape cosmetically and function well (the longer minimum focal length of the 70-200 f4 from 180mm scared me until I discovered that was normal behaviour). But the lcd screen on the A7R has a lot of pixels that are dead. Lines of pixels running down 10-20% of the screen. There are 5 or 6 areas affected in total, though these do appear at the margins. Personally I can accept they may not have noticed but nonetheless, I don’t consider it 'mint’.

I just wanted a sense from the community on a) if this is a common occurance on this model, b) if this is a problem that develops further or is likely to be as bad as it'll get, and c) am I over reacting to want a refund on grounds of it not being as advertised (ie. should this be considered normal on a device of this age? - never happened on my a700, 900, 77 or 99 but then maybe I was lucky?).

I find new LCD panels starting at $13. The most expensive one I see is $60 which is already installed in the frame. I don't think those dead pixels would bother me much, but it is fair to return it or ask for a partial refund.

I can't speak to how common it is, but my a7R also developed a line/blotch of dead pixels on the top-right corner.

It however, was much older and much more used than I think your 'minty' one is.

Maybe a silly question but are you sure it's dead pixels and not some residue effect of a screen protector?
Lines of dead pixels would be rather uncommon unless it's the "lead" for a whole row of pixels.
I'd take a look with a magnifying glass under some strong light, with the camera turned off, dead pixels ought to be invisible but something physically on the LCD (underneath a glued on protector for example) ought to be visible.

Unfortunately it's not a screen protector issue, I've checked with screen off and it's not there. Definitely a digital thing. I've contacted Sony to find out about a repair, but pretty sure Pencoed in UK have a flat fee of around £130 and not sure it's worth that - either to the seller or to me. Will see what they say.

Reassuring to hear others haven't had this problem though.

Bit late replying but I experienced something similar with my (approximately) 5 year old A7 when I used it last summer. The affected pixels were along the bottom edge of the screen. The camera wasn't getting used for months at a time. Weirdly, after an hour or two, the issue disappeared. I have used the camera a few times since and issue hasn't returned. Strange.
