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.

 

Other than connecting directly to the mains being a topic not discussed here, I do have one question?

Is your capacitor really 225000 farads?

 

I replaced the capacitor 225k 400v with another one, same, and it give me 22v, my main power voltage is 220

 

225K = 2200000pF = 2.2μF and K is a 10% tolerance

 

Sorry it is 105K not 225
but i replaced with the same value, maybe i need to replace it again?

 

No, you don't need to do that. Try to add 220Ω/0.5W resistor in series with capacitor.
And R2 resistor wattage is ? More than 0.25W

 

I think it is more than 0.25w but idk the value, it is the blue one in the picture

What the useful for adding 220Ω 0.5w if i can add one resistor for example 1.5k 0.5w, in fact i added it, and burned?.

 

LEDs directly from mains is extremely hazardous, as well as against our Terms of Service. Think about using a Wall Wart.
