Re: toshiba C660

you have to move to the right and keep testing.
take PL210 and see if you still got short.
charging rail may be shorted

i mean that pq204 is not shorting in its place, its place is not shorted, but when i insert a new ic and put the ac adapter , then the ic is shorted.

Re: toshiba C660

then its much easy.
take them out and test all the fets around. chg_b+ all the line you got like 4-5 fets.
inject 1v on the charging line near the coil and see if you feel something gets hot.

try something maybe you get lucky!
if you do anything post the results.
good luck

i injected 1 v on the coil and saw 0.58 A but no thing is hot

Re: toshiba C660

the problem is that if you left the coil there its hard to know.
you must take it out and see where it goes with 0.5 A.
you understand me right? its like put your hand in front when you cant see.
you need to see where it drains to go that way.
