Yes. I see that, but the strange thing here is that it doesn't work with either boss 9v or palmer's power supply.

insane.
When I did open the box yesterday it came out a lot of metal spoon/dust. I did take a Q-tip and did have a electro spry on it and clean it carefull an now it work.
How can that be?

So the LED does light up again and everything works as it should?

Yes. It did. My wife did see this to, she did help me to see the light under the pedal when I did use the meter and we did not understand any thing at all.
Now after dinner I did try It again with the T-rex it did still work. when i test it with the Boss and Palmer it don`t work. (didn`t have time before dinner)
I give up.

Thanks for all the help guys

@laurie:
Could it be that my earlier suspected zener diode might have broken into pieces and now some sort of contact has been made with the cleaning procedure?

We would need clear close-up photos of the circuit board.

@Tnsen, would that be possible?

I`ll see what I can do this afternoon.

Fresh Photos for you.
Did see a video on you tube. Thar was someone who lubricated the Inn and out of the pedal with elecrospray, then he got better contact, has anyone tried it out?

D6 and R51 (that supply the LED) both look OK visually.

@pepe - I wonder if Q8 has failed?

Tnsen - can you use a meter (set to DC volts) to measure the voltage across this component? Measure it with the effect bypassed, and again with the effect engaged.

This is a standard thing to do. It won't affect whether the LED will work.

If using a spray, spray the plug on the end of a guitar cable and then insert and remove the plug 4 or 5 times. Don't spray into the pedal.

Use only products marked "contact cleaner". Do not use products like WD40.
