That sounds like a surface mount resistor. It may be difficult to
impossible to repair without a schematic, but I'll have a look at the
picture anyway when you post it. It is sometimes possible to arrive
at a suitable resistor value using "suck it and see" techniques, and
by using an educated guess by examining the circuit. However, this
resistor certainly did not fail on its own, there will be damage
elsewhere as well.

Not to be negative, but....

The OP doesn't have a schematic, and doesn't have SMT skills or tools.

Good luck.
