A logic probe is placed on the output of a gate and the display indicator is dim. A pulser is used on each of the input terminals, but the output indication does not change. What is wrong?
The dim indication on the logic probe indicates that the supply voltage is probably low.
The output of the gate appears to be open.
The dim indication is the result of a bad ground connection on the logic probe.
The gate is a tristate device.

Sometime supply problem occurred or properly connection is not in circuits or gate output is not properly connecting to.

When output does not appear, at that time only one problem occurred like not proper connection between output & probe.
