2 What causes these static and moving horizontal lines on display?
I saw in last month these year som flickering after I open display or I typed. Then show up black line at bottom display. Then more and more, maybe because it was more warm outside.
Last week I have macbook in room, normal temperature, and came back after 30min and lines flickering like shadow on full display was added.
I connect it with HDMI and it is OK, screen mirroring is OK too but that is just software thing I think.
I remove battery, of course then I discovered that apple suppress cpu load, and heating is no longer problem. Fan works OK.
Display connector seems to be properly sealed.
Battery I buy if I know where the problem with the screen is.
Q what this can couse that issue ?
Q where can be problem ?
Q what else should i look at ?
Thx
