Hello,
i have problems with an 820-3115-B. The board had bad water damage and no green light. I cut off the bad damaged Thunderbolt area, replaced the SMC and a lot of other stuff. Now it has a green light and turns on again. The remaining problem is that it beeps if i take the ram out (speakers are ok) but wont chime. Also it has no Picture and no Backlight (missing LCD_BKLT_EN ; i already exchanged LP8550 and the LVDS witch were damaged too) Could it be an SMC Issue (bad soldering or maybe bad SMC ; but it has a green light after the SMC exchange)? At this point i´m stuck.
Thanks for any help!
