LIDL bug zapper not working
wasedadoc:
Your schematic shows the light and zapper to be independent circuits. No reason why a tube problem would affect the zapper. Not much to be faulty in the zapper. Measure the voltage from the single rectifier side and from the voltage doubler.

If you bought it for mosquitoes, sadly it doesn't work. Mosquitoes are not attracted to uv light. This thing mostly exterminates little flies and moths.

Yes, light and zapper are totally separate. I have experimented some more and touching the zapper wires with a wet leaf does produce very tiny sparks. I was hoping for a satisfying ZAP! but I guess the tiny spark might be enough to zap the insect.
I guess if I want to increase the zapping power I could increase the value of the capacitors and reduce the value of the series resistor.
In fact, I bought this one to replace an older unit which I assumed was bad but it might be the same thing, that the zapping power is just too small but still there. I still have it and I will have to test it again. The light in that one works fine. Maybe I did not need a new zapper after all.
So the issue remains with the light not working and I am still not clear on where the problem lies. The individual components seems to be OK but they do not work together. In the worst of cases I can just add the magnetic ballast because the light works fine with that one.
I should have left this long ago but, as usually happens, once I get started I can't let go.
I have redone the schematic in order to make it clearer.

No problemo. The mosquitoes where I live self-identify as houseflies. ;)
