MacBook 12 2016 display glitches
I've bought it from Gumtree and now I've got problem.
The problem what I've got is display shows "glitches" (colourful mostly horizontal lines) - strange thing is - only on white background - when connected to TV - it is fine.
Case/lid got no any signs of damage.
I was wondering it just display flex would fix that - www.ebay.co.uk/itm/401409712743
Apple says "just" £500 for fix which is a bit - oh jesus christ :(
When I purchased it - it had.... El Capitan on it.
Glitches horizontal lines are/can be everywhere on display (not just in one specific place) when booted.
Not a single glitch when white Apple boot logo on black background + white progress bar + text about how much time to complete installation.
It has SMC 2.35f105 - but BootROM bit old (I think - MB91.0159.B00) - I'm doing now Combo Update 10.13.3 - hoping it will update it.
In this photo glitches "fallow" the window when it is moved around
