Copied this Astable Multivibrator exactly as per Examples and mine doesn't switch. Had lots of circuits that I built do the same.

Your circuit is dimensioned to blink at a frequency of ~2 Hz. Your simulation speed is set to 1ms/s. Set your simulation speed to real time (1s/s) and the wonder will happen.

Change the timing,clock

Hi Andi, Appreciate the feedback. Changedto 1s/s but it still doesn't switch. Both LED's stay on and both transistors

Sorry both transistors are saturated. Hi Jeff Which setting is the timing / clock?

Hi Guys. Strange! I added a ON/OFF switch for the 5V supply. Switched OFF and noticed the capacitors discharging. Switch ON and it works!!

I think that the circuit is too much in balance due to ideal parts, wires and symmetry. It could help if you slightly vary one resistor on one side or you could use the noise adding feature (shake the circuit).
