A few hints: 1. those funny looking characters help the readers a lot: .,:;!? 2. did you have a look at your video before sending it? 3. add some information: did the tester run till yesterday and now ist faulty? Or did you build it and got this behaviour? 4. what supply do you use? did you measure the supply voltage at failure?

Mir scheint der Finger zu nervös zu sein. Einmal NUR kurz betätigen reicht! Der Schalter wird viel zu lange gedrückt! Der Tester wird o.k. sein. Trotzdem wäre ein schärferes Video angebracht. Sorry, das mußte ich jetzt mal bemerken.

If the LED-polarity is wrong, the circuit wohnt work. It has TO shine, when Switch is pressed.
