Thanks Duke!

Does anybody happen to have one of these laying around & can test some components for me. I have one ripped pad on a resistor & a popped cap. Popped cap is on 1st image on left.

This one had liquid but board looks clean no corrosion. There is PP3v42 and KBD_ONOFF_L goes low with power button. This is a 2015 so no ASD. Is there measurements or test you would like me to run/take that would help you understand what could be the problem. The machine seems to function fine...

This one turns off and magsafe light goes green when you tap the power button. I have tried a good keyboard. Any suggestions? Thanks

3.3 v on C1802/03. No pulse on L7260 that I can see. Thanks, Duke

This one had liquid damage around u7200 and SMC all s5 rails present but no PM_SLP_SUS_L. Thanks

No short with only cable connected. Signs of liquid in the display also. Thanks for the help Duke and 2Informaticos.

Yup, there is a pulse but voltage was not getting through U8300. Replaced and cleaned corroded pads and all is good with test LCD. Original LCD has a short on PP5VR3V3_SW_LCD. Do you think short could be in the display cable or is LCD shot?

OK, I will check this tomorrow and get back with results. Thanks

Hello Duke, No LCD_PSR_EN so 0 Volts on L8300. I did test with a known good working LCD. Correct me if I am wrong but isn't 820-4924 a 2015 board. I have a known good LCD for 2013-2014 I can try if I am incorrect. Thanks

Yes, EDP_ PANEL_ PWR is present and C8320-C8329 & FL8300-FL8303 are in place. Thanks

Hello, I have an 820-4924 that came in with liquid/corrosion around U8330 area and does not display video to internal but does to external. I have cleaned, replaced U8330 and tested with a working display. All components in the area measure correct but I am not getting LCD_PSR_EN. Can someone...
