dtx1 Posted June 27, 2021 Posted June 27, 2021 Hi, after some time on storage i tried to reativate my batch 2 helios4 only to be greeted with a seemingly broken device. Tried the following: 1. Flashed a new good SD Card with Armbian (golden sundisk one) 2. unplugged all harddisks in my helios 4 3. inserted SD-Card and plugged in in. Result: Orange blinking on the Network Port Green blinking next to the Power slow USB-TTY does not show up Tt does not boot I hear a slight chirping noise synchronous with the green LED. It comes directly from the board not the fans, harddisks or PSU. Sounds like a fan briefly rubbing against something but it's comming 100% certain from the board. Is my Helios4 broken? That would be absolutely saddening because theres no ECC Memory Replacement available. Any Ideas? 0 Quote
Heisath Posted July 2, 2021 Posted July 2, 2021 Measure the power output from the power supply. Make sure to have everything disconnected from the helios and no shorts ( dont put it on a metal surface ) before trying again. For measuring the power supply, you can either measure on the power plug directly or on the hdd connectors. Check the images here: https://wiki.kobol.io/helios4/hardware/#connector-interface-list (J19 middle two pins are GND, outer pins should be +5 and +12V; careful not to short them!) 0 Quote
Nathan Driver Posted July 6, 2022 Posted July 6, 2022 I have the exact same problem. The board does not recognize any HDDs, attempting to boot it solely off SD card (with HDDs and fans disconnected) one can clearly hear a chirping sound coming from the board itself. Can anyone recommend a good replacement AC/DC adapter? 0 Quote
