Hello all,
This is my first post.. so HI.
Recently my Computer Keyboard stopped working. I opened it up to notice that
the circuit had corroded. I need a circuit writer pen to rewrite the circuits. Does
anyone have an idea where to get it from? I'm from Hyderabad. I'm ready to pay
for the shipping costs too, if someone is willing to ship it.

I have never heard of a circuir repair pen and I am an electronics engineer.
Best thing to do is to ditch your old keyword and buy a new one.
It does not cost much to buy a keyword.
