Nova Posted May 1 Posted May 1 Hello, I am experiencing a critical issue with my Helios4 board from Kovol after a recent power outage. When I power on the device, the fans start spinning, but none of the LEDs illuminate at all. This includes the power LED and any activity LEDs. Anybody can help me?. I thought it might be the power supply, but I can't find where I could buy it. Does anyone know where to find it? Thank you very much. 0 Quote
Nova Posted May 1 Author Posted May 1 My board have a UART1 (via onboard Micro-USB converter) and dont connect...... with $ sudo picocom -b 115200 /dev/ttyUSB0 @Werner Can you think of any other option? Thanks for answering and for your time. 0 Quote
Werner Posted May 2 Posted May 2 Try with a fresh image on sdcard. If there are SPI or eMMC and a way to disable them hardware-wise (I don't know this board) disable those. Check if it boots. If there is no output at all with the fresh image the board might be damaged. 0 Quote
Nova Posted May 2 Author Posted May 2 @Werner thanks for your time. I found the solution in this post: I'll never be able to say it, but this community is the best I've ever seen. I want to thank you because once again, I couldn't have solved the problem without it. Thanks @djurny@Igor and the all the people of this post. 1 Quote
