Bad Time for the Clock to Stop

[kk13]

This happened in my game tonight, High School Varsity Boys. Visitors make a basket to pull within 3 with time running out. They do not have any timeouts remaining. Ball goes through the basket home team takes the ball to inbound. I am the lead-becoming new trail. I start my count and I see 5.3 seconds on the clock. I get to 5 seconds the only problem is that the timer for some reason stopped the clock at 1.6! What do you do? I will wait for some responses before I share what our crew did.
