Derek, Try to lift all these 50 and 100pF caps from GND and connect them directly to GND pin of the brain chip. Exercise could be tricky with SMT. If there are more GND pins, use nearest to x-tal pins.
Sometimes there are resistors, two in series and one across x-tal, but leave them for later. Do not connect other circuitry unless you calm down brain chip. Later on you may add resistor in series with clock output pin, value depends from circuitry 56 to 1000 Ohms. Regards, Mirko
