Good evening guys,
i have a problem with Acer a515-55 board: dazauimb8c0 rev c, laptop comes with flickering screen, sometimes it wasn't coming on at all.
At the beginning I thought that laptop does have problem with LCD Flex, i've changed it, it worked for few hours then it stopped displaying at all.
I can see backlight come on the screen, stable blue light on the side, 0.70amp draw, I've tried to connect USB keyboard, caps-lock light does not appear, so i assume it doesn't POST.
+VIN_BLIGHT 19.5v, +vlcd_con_r_c 3v, VLCD_CON 3v.
Any advices what to check and what to test? LCD & Flex been tested on 2nd fully working laptop.
On board ram micron, CPU intel (don't know which one), new bios checked, nothing changed.
In attachment, you can find schematics and board view.
