So bro can you let us know how did u fixed the unit, I have the same issue on the same module. Does 2.2PF 2kv SMD CAP really exist? I can only find the 50v type.

I think the OP said he used a leaded cap for the replacement.
I don't know where the 2.2pF value came from but that seems too small to do anything useful in that circuit.

I'd put in a 1000 pf 1000V leaded cap and call it a day.
