Removed jtag yet? Voltage on smc reset?

 

[borderhunter]

Yes..Smc Reset 2.817v

 

[jason_microsoldering]

Too low, check smc reset area and pull up resistor.

Check J6100 for corrosion. SMC_RESET should be 3.4V. Check U5110 and R5100, else it could be crap under SMC or dead SMC.

 

[borderhunter]

Smc reset voltage ok 3.4V Stable

but PP3V3_S5 => 0,03V
