Basic troubleshot
Connect only the ic and power nothing else
1) Measure with a multimeter voltage between pin 7 and 14
2) Connect pin's 1, 3 , 5 ,9 ,11 and 13 to ground and measure voltage on pin 2,4,6,8,10 ,12 ,Voltage in all must be +Vcc
3) Connect pin's 1, 3 , 5 ,9 ,11 and 13 to Vcc and measure voltage on pin 2,4,6,8,10 ,12 ,Voltage in all must be 0
4) disconnect all pins except the power supply, and connect a 100K resistor between pin 1 and 2. With a scope check if you have a very high-frequency signal on pin 2 ( you made an oscilator with the resistor and spurious capacitance.
5) Maintain the resistor and add a capacitor from Pin1 to ground, now the frequency must be smaller.
After you reply on this I will give you extra instructions
