Black Star Nova 200 Frequency Counter
« on: June 21, 2018, 03:29:58 pm »
Hello, I've recently purchased a Nova 200 frequency counter and curious if anyone is familiar with its first power on state.

When I turn it on all the LCD zeros flash up then go off until the first gate loop starts. I wondering if this is normal?

I have replaced all the electrolytic caps and 3 tantalums thinking they could be the issue.

When I first received the counter it wasn't doing this, then after a day or two it started ,so naturally thought the caps could be at fault.

All the capacitors replaced and any possible dry solder joints have been reworked.

Any ideas or even if this is common on other counters. I just hope an IC isn't about to fail!
