Do you mean light at DC jack blinking?? If so look for THERMAL PROTECTION.

Using a genuine charger to test with ? . Check AD_TYPE

Power down. Meter in resistance mode.

Check and post the resistance to ground of PL16.

pltrst# -0v
rsmrst# - 0v

IS there any point in measuring pltrst# at this stage?? RSMRST#-On some mb's it should be 3.3V before poweron but on some mb's it comes after turning on. So I'm not sure it should be 3.3v before poweron or not

MAINON at 2.2V doesnt looks good. So trace this signal. I beleive it should be 3.3V

I tried to pump voltage to the 5v coil and the Ic was getting hot but I dont have a parts right now just making sure that I just only need to replace the ic?
