Hey guys, got given a benq fp737s, plugged it in, saw flashes of the screen, out of range msg (probably coz of my vid card settings), the screen flashed and smoke started coming out the top! Filled my room with acrid burning odours

I opened it up, it seems the filter capacitor is blown: capxon 100uF 450V. I think it leaked a white plastic like substance over the board. So did three other (ceramic or tantalum?) capacitors (similar white substance - feels like rubber).

Electrolytic caps all "look" good..

Im guessing something happened in...
