iSight camera light always on

i got this mac book pro 2010 off someone that did not power up no matter what i did.so i toke it apart washing down the motherboard and all components inside.no visible water damage anywhere.only some beach sand inside.it was in Mexico before all the troubles started. now that it powers up only two issues. i camera light is always on. and no sound. tried headphones nothing .did all type off resets on the mb.

shows no audio output under devises. only static at start up.also tried another hard drive with snow leopard to make sure it was not software related same thing.wondering if anyone has any ideas.or should i scrub it down again.thanks.

Try to unplug the magsafe and take out the battery, hold down the power button for 10 seconds, then replace the battery and power it back on.

Do an SMC reset, as you were instructed, then a PRAM reset. To achieve a good PRAM reset, boot up the machine keeping option+command+p+r and keep them pressed until you hear three "boing" noises
