Check your solder joints on all pins of chip UCL1.The solder pins looks good.
If the solder joints are fine
measure the voltages to ground on pins 2, 3, 8, 9, 10, 11, 14, 15 of chip UCL1, when the machine is turned on (power LED is turned on).
2 - 3,3 V
3 - 1,07 V
8 - 3,3 V
9 - 0,6 V
10 - 3,17 V
11 - 1,81 V
14 - 2,74 V
15 - 3,27 V
