Bad V5

[KolyaN]

I have all reference volatges right except V5 which is -3,4 instead of 1,6v.

Oscilloscope is working though I am still adjusting capacitors around C8 (got "too much" compensation on the first try) and exploring battery connection.

Also with test (square) signal I am not always able to set Level to have a proper sync.

Should I bother about V5 or leave it as it is?

V5 is the signal for frequency counting. It is a digital signal usually at around +3.5V or -3.5V and won't stay at 1.6V.

Did you try adjusting trigger level when display was out of sync?
