If you download the PDF you have three pages. Not only the two from ther preview.
And on the third page (ZLX Input Board MCU) you can see the circuit for the lcd display with the chip (I2 - STM32F100C) wich is also for the display.

You can try this link https://elektrotanya.com/cgi-bin/download2.cgi?dk=fj0znb2vmtw4wrsjidg832ic8emz4fu35r35wbn6pvvgz1su&fid=332884&file=electro_voice_zlx_15.pdf

After the repair, the board turns on again. Smile
Unfortunately, a loud, high-pitched buzzing sound can now be heard.Unhappy
The frequency of the PWM CHip (TL3845) at Pin 6 is ~28kHz, the original board have ~370kHz!

I mean, I immediately changed all components from the 9x1Ohm resistors to the optocoupler.Confused 
Does anyone have an idea where the problem is?
