[SOLVED] Mid 2015 820-00138-A display corruption

[bridportpcrepair]

Hi all,

Got a Mid 2015 MBP here with the 820-00138-A board which has presented with a corrupted screen.

Mac will boot, chime and the screen will fade to green with a fairly solid white line running down through it.

It IS a Retina model, I've had similar issues with the 13" screens when they've been dropped, but this one isn't quite so straightforward - the customer was using the Mac to watch TV when the display 'went', so no liklihood of physical damage. Board looks visually clean with the usual dust here and there, no liquid damage to be seen.

Are these boards prone to any GPU failures? Is there something else I should be looking for?

I don't get a display on an external monitor but to be honest I'm not using the best of adapters to test this with (don't often deal with the newer Macbooks so don't have a lot of kit to test with!).

Cheers guys

Try another screen / cable.
GPU issues are not common (I've never heard of or seen it).

Thanks G.Beard

I've attached a photo of the screen - I reckon it's an LCD problem to be honest but the method of (reported!) failure doesn't really match up - although as Louis says - "People lie"!

That looks like a cracked screen...put a 15" 2015 screen on it and test

surely you have TV with Hdmi cable. disconnect the lcd cable then plug a hdmi cable then switch it on.

that doe looks like a bad screen

Alan.L - my apologies, I'm so used to looking for a bloody Thunderbolt port that I completely missed the HDMI port on the side! (In my defence, I'm on holiday from today so not really been thinking straight!).

A perfect picture with HDMI - so panel it is (or certainly should be!).

This is for sure broken LCD, seen it so many times
