When I open the lid, screen fades to white and goes flickery

When the lid is opened past 30 degrees the screen starts to fade to white and flickers untill you can barely see what is on the screen.

When you close the lid back to 30 degrees its like a switch and screen comes back to normal.

Otherwise works perfectly. Works to external screen ok.

I know older machines had probs with screen cable but they seem to result on screen going black.

Thanks in advance for any help

Yes, the older 2016/17 systems had a backlight cable issue what was called FlexGate!

In your case the issue is within the T-CON board and the LCD panel. There is a set of cables which connect between them so the board can paint the screens image. The reset signal is not working so the screen just additively adds the following image on top.

Hi

I believe you have a issue called "flexgate" ;-{

Flexgate is where the screen cables start to break apart and perish

I was testing a A1989 MacBook Pro's screen a day or so ago and it had the exact same issue as what you are reporting

unfortunately the only long term fix is to ether have the display cables replaced which hardly any people do or have the display assembly replaced

Hopefully this helps

Any questions please ask

Thanks:-)

I thought the 2018 model had been fixed?

I thought I would probably need new screen, ouch!!

Oh well better dig deep and shell out.

Thanks for replies

Yeah they ”fixed” it

In all fairness on the 2018 and above they did make the screen cables longer to try and avoid the issue but it unfortunately does still come about it’s just not as common

@hellomacos @alanhancock31 - Here’s a good write up on FlexGate https://www.ifixit.com/News/16943/macboo... and the 2018 onward systems don’t encounter the issue as you can see better explained here https://www.ifixit.com/News/13979/apples.... That still doesn’t mean you still can’t encounter a backlight issue! A good bang along the black clutch cover or something wedged between the uppercase and the display bottom edge (chin-plate) which is a thin piece of glass which covers the cables going to the LCD panel can be damaged. The backlight goes out, black not white
