I have a problem with a monitor Model L-151, Type: L5AK6 with input 12V, 4A
It had a power supply problem at first so I replaced the power brick (12V, 4A)
Checked the inside and found a blown mini coil (L) and a circuit AIC1578CS
The coil goes to the invertor and the circuit gives 5V to the main board as I figured after replacing the circuit
Now my problem is that even after replacing the burned parts, the monitor still doesn't light up ... no power led - green or orange
Checked the backlights and they are working (with a inverter that i keep just for testing). The inverter has no blown fuse and the 4 transistors are working.
I need some guidance. Here's a photo:
L015 was the coil
U003 is AIC1578CS
U004 is a mosfet that I replaced at first (works as it gives 5V to the main board)
I even reconnected all the connectors
