Identify and replace a resistor
Those resistor appear to be 0805 package 200 &Omega; 1%.  However, all that crud around the resistors is a bad sign.  These things have apparently been too hot for a long time, although that still doesn't explain all the crud.  Resistors don't leak corrosive stuff like that.  It's also very suspicious that the capacitor to the right seems to have brown stuff on its solder miniscus at both ends.  It looks like flux, but flux wouldn't end up there like that.  I'm thinking that maybe the long term overheating helped along by humidity broke down organic compounds in maybe the solder mask or residual flux, although I haven't actually seen that before myself.

In any case, the verdict is the same.  This unit is toast.  Done.  Kaput.  Forgeddaboudit.  Two resistors wouldn't just overheat on their own for no reason.  The fact that they are dead, and took part of the surroundings with them in the process, looks more like a symptom than the root cause.  Toss this mess and move on.
