Solenoid Overdrive LED blinks. Problem.

[Bumblefoot]

Hello friends. I've already assembled a few pedals and they sound really great. But there was a problem with this one.
When the pedal is turned on, the LED starts blinking at an interval of ~ 0.4s
This does not depend on the inclusion of jacks. There is no sound.
She does the same in the box.
Visually, I don't see any problems.
Maybe I mixed up some denominations in detail ... I double-checked the main ones.
Maybe someone will tell you where to look for the problem?

The LED blinking could be a short tripping the protection in your power supply, I had it happen on a pedal and it turned out to be a tiny stray wire causing my power supply to do this. I’d see if you have a short to ground by checking continuity to ground on both sides of the protection diode.

Exactly. I didn't think about it and it looks very logical.
I will look for.

Friends, my knowledge is not enough to draw the right conclusions and find the problem)
Here is the data I received:
There is no short circuit to ground on the terminals of the protective diode.
I carefully reviewed the soldering, soldered the dubious elements (as it seems to me).
I also measured the voltages at the control points.
I don't understand where the anomalies are

In the meantime, I discovered that my blinking LED circuit behaved the same way with a battery.
It turns out that this is not protection of the power supply from a short circuit.
Looks like I'll just rebuild it)

I keep you informed.
I feel like a donkey))
In general, after numerous measurements, I invariably came to the conclusion that something was wrong with the LED ...
It turned out that somehow I bought a blinking LED. And it was him out of 30 that I decided to put. In principle, I did not know that such LEDs exist.
Well, now I know, like you))

Thanks for the heads up. I didn't know such things existed either.
