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

Hi New to the Forum.

Can anyone send me a copy of Page 2 (amplifier section) of EV ZLX-15P speaker, please?
    
email fatih2515@gmail.com

I am repairing one at the moment. I repaired the common burnt out power supply issues and now have power supplies +/-15V 3.3V, +/-40V. But whilst the tweeter works I just hear a large pop on power up and power down - out of the Bass speaker.

I have replaced the Bass driver chip TDA8953 already.

Now struggling, any advice?

Thanks in advance

I have repaired 4 EV speakers. All of them the same failure. SMD  capacitors ( 10uF as I remember ) list their values. So change them all.
