Board DAY11AMB6E0 REV E - https://www.badcaps.net/forum/attach...1&d=1474124578
Known good LVDS cable and LCD screen.
Laptop works fine with HDMI connected.
LCD is controlled by Realtek RTD2136R (page 23)
Pin 5, 18, and 22 should have 3.3v input but actual voltage is around 2v.
The schematics call these 3.3v rails "+3.3V_2136_A" and "+3.3V_2136_D"
The bottom of page 23 says these rails originate from a rail called "+3v" which isn't very helpful.
Trying to figure out where these rails originate from, and why they are low.
My best guess was PU6 (page 43) but this IC does not exist on this particular board.
Now I am kind of lost. Any idea? Maybe bad RTD2136R pulling it down?
