So the actual schematic still hasnt the ground connection on the other side of the voltagedivider and the LED? Seems strange to me. Anyone tested if its working this way? Cant imagine that unless pin 16 of TL494 is able to provide a ground somehow... Or am i totally wrong? Maybe one of  the pros here like verpies or TK can have a look at this and give a statement?

I think wrong schematic In OP.. There are two floating around and the original had ground

If you think the schematic is wrong, then build it your way and share the results. If it works your way
then we'll copy it.

In electrostatic induction the term "ground" can be misunderstood.
A large object can suffice as an electron donor.
This includes the human body, which explains why people can
light bulbs remotely, by holding them.
It can also include the negative terminal of a battery or the case which contains the device.

I am talking about the one the pcb is based on.. There are two versions  of this circuit.. The one in the op was modified from original . and calm down I am working on this just trying to clarify the confusion on the ground

I am on my phone otherwise I would post it for you.. Perhaps grum can post both versions as he did over at OUR
