    Hello. Looking for SPI U3 / W25Q32FV memory chip, CV9203L-A motherboard, CX185LEDM matrix. The electrode offers several solutions, but none of them works. The red standby LED is lit and there is no response to the remote control.

    I checked and it does not work. Still a "dead" remote and only the green LED is activated from the keyboard.
