It's easy with the board in your hands, but MUCH more difficult to do from pictures of both sides.
Here's some examples of transformerless power supplies, along with explanations.

Please where is it, I have not seen itIt's easy with the board in your hands, but MUCH more difficult to do from pictures of both sides.

Ok, will try thatYou need to trace out the circuit by looking at the connections formed by the copper tracks on the underside of the board. We also need to know what all the wires connect to.

I don't know,but I will check the clipperloose wire?
It's MST - presumably the manufacturers name. eg.Please what is the meaning of that MTS written on the LED panel?
The most anyone could tell you with just your picture is that it is a surface mounted LED and probably white light output. (The yellow colour which is probably to correct the colour temperature of the light is what suggests that it is a white LED.) You were requested to trace out the schematic of the device 8 days ago but have not provided the information. So far you have no evidence that the LED is the cause of the fault. Fault finding is a logical process. Not just randomly replacing components, We expect YOU to make some EFFORT to help find a solution to the problem.

The other one you asked for the schematic of the device I came to discover that the battery is dead totally, so I want to change the battery and see what happens first before proceeding, That is why I keep quiet for the main time.The most anyone could tell you with just your picture is that it is a surface mounted LED and probably white light output.
