3110c there is a reading from powerswitch pin to ground.
the unit will automatic power on and off always. there's always a resitance reading between power switch and ground.

i try everything in this forum change ristors, change retru ic but still no luck.

we need to solve this in this forum.

any idea!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i also tried remove capacitor near the resitor switch lines but still there's always a reading.

i think it's the circuit board but i will not conclude because no one solve yet.

i already removed these parts and changed retue but same result.
set auto on off
any other idea?

in my idea we need to condemn lines from power switch to retru ic by removing the pin in retru which is from power switch line assignment. and we will put direct jumper wire from removed pin in pcb which was retru placed. i will post result soon in my experiment.
