I have a circuit in which when output of comparator circuit is high (22V) led 1 should be off and led 2 should glow.
But problem is LED 1 is still glowing it is not switching OFF .I checked the voltage difference across R14 it is 22 V(Vcc=22V) on one (LED)side and 9V on other side due to which LED 1 is still glowing.
How to resolve this issue ?
