Retina 13" 820-4924 - No Display

[patrickribbsaeter]

820-4924 ( changed the SMC because of another problem with charging the battery and then shit hit the fan. The display stopped working!

• SMPS = 20v, power up on 400amp, and then stays at 700amp.
• NO Display
• Red water marks visible. Small corrossion on two components next to U7700 (backlight IC). Cleaned up!
• U7700 (VDD = 5v)
• U7700 (VDDA = 5v)
• U7700 (EN = missing) (I searched the line back to U8330(VCC = 3v) but missing the other lines EDP BKLT EN & LCD PSR EN & EDP" "PANEL PWR

What could be the issue, those lines come from the CPU. But there was display before i changed the SMC. Could the problem be the new SMC?

Reball and put back its SMC.
BTW, does it charge the battery now?
