FPV CCTV board camera needed urgent

[MKARTIKGANDHI]

I don't know how it happed but I think I burned of short circuit my board camera ..
When I connect it it gets very hot within few seconds ...no output image is there and in few more seconds a bad burning smell comes out
I check polarities and input voltage also everything is fine .....if I can do anything else to correct it please suggest

I would like to buy a board cam 700tvl or above ... Used one is fine. I want it under 700-800
