Pressing the BP5 Power on/off button has no effect..
You are not getting Voltage feeding the D pin of the IC, you need to check the Voltage between the two legs of main filter cap C4 (Green cap next to the resistor) first and also check your soldering works.
BTW, 100 Ohms is too high for that fusible resistor, but of testing purpose t is OK for now.
