I put a TA driver with narsil in my mf01 and first time i turned it on it got over 15000 lumens on turbo. Iswitch the light off turned it back on and now it will only ramp up to around 4200 lumens then it shuts off.If you double click to turbo it shuts off. If you ramp down light will turn back on at around 4200 lumens.I checked pin 3 on mcu when it cuts off a voltage of 4.9 v is on pin 3. ramp back down till light comes on and voltage cuts off on pin 3. Any of you experts got an idea .
I have narrowed down the problem when i put pressure on number 4 pin on fet light will come on. I reheated the pins on fet and it worked for a second then back off again. Can an fet be removed and reflowed with a soldering iron.
