Multivibrator - cant find solution fixed

02:22:22

Hey guys, anyone know why this sim can't find a solution? If i change the capacitors to 10uf instead of 100 it works. Am I missing some fundamental law here?

Check your resistance

Change base resistors to 30kOhm. Monitor collector voltage. Open & close switch to force start (or you can shake phone to inject noise).

Also, remove LED as it is clamping collector voltage to 2V and probably causing error condition.

Change timebase to 1 second

Thanks guys! I did try changing the resistance and it kinda worked but it was still a bit temperamental. However removing/ changing led location fix the problem. Thank you!
