La-e541p

Re: La-e541p

Another know how.. I remove PQ712, I get all the voltage on the Gate of PQ740 which is 24.5V a true voltage out here meaning ISL88739HRZ is working fine, but as soon I solder PQ712 the voltages drop again. PQ712 is not short & I also checked PQ707 (Protection) all seem to be fine. Do you think I should replace PQ712??? I also check PQ705 & PQ305 (Charging MOSFETs) & the surrounding caps., all seem to be fine. I removed the resistor PR913 to check if any short further but still the same. So there is something going on before this resistor. How come voltage is dropping???
