Re: Acer Aspire D270 dead
thnks for the reply..I already checked that sir.. 19V input of PR190.. output is 3.3V to VIN of RT8233M.. i checked the PR190 its 114 ohms.. labeled at 100 ohms.. it is ok? 19V became 3.3V after the PR190?...Leave a comment:

Re: Acer Aspire D270 dead
I replaced the ISL88731C and there's a output now.. but another problem occurred.. there's no 5V and 3V output in voltage controller IC RT8223M.. there's no supply to the gate of MOSFETs.. VIN of RT8223M is 3.3V.. any idea? thnks in advance..Leave a comment:

Re: Acer Aspire D270 dead
Sir dizon, if UGATE is 0.2V of ISL88731C, so no gate input to AON7410.. It is considered as defective? There's a 19V in CSSN of ISL88731C..Leave a comment:
