I am trying to fix my "LEDs with battery emergency light", charged from the main power by using X/Y Capacitor (X Rated)

Here is the part of circuit

The problem is the R2 for led indicator of charging, it is burning, i replaced all components except the board, but still burn, this product worked before with me for 2 years before i found it burned 2 risistor, and one transistor, name and values of components written on the board so it easy to replace the damaged ones.
I Replaced the R2 with more higher wattage but still burn and smoking, the voltage before this resistor is about 22 volt.
I cant find why still burn, the led replaced twice, R replace to 2k, same.
Any idea to check what the wrong?.
Thanks in advance, i am just a programmer fixing my tool with my self, so sorry if i put the topic here with Home work.
