Additional information for user reference,
1. The LCM shows “Self testing” means the LCM is power on and it’s waiting OS(Operation System) to send text
2. Thecus NAS is similar structure as normal x86 PC, therefore we are able to identify this status via normal PC diagnostic method. We just need to confirm the BIOS ready beep sound since NAS is power on in 10~20 seconds. If everything (CPU, DOM, RAM etc.) is installed correctly, but no BIOS ready beep sound and we suspect the motherboard has some issues and need to swap or require RMA Service.

Furthermore, some of Thecus NAS are with video output (VGA or HDMI). User could confirm the BIOS ready beep sound first. In addition, user is able to connect the rear video output port with a monitor, too. If the output shows system successfully operation, then perhaps the NAS LCD display defect and require RMA Service.

If the output shows abnormal, please
1. Re-plug DOM, RAM, and CPU etc. to confirm whether the self testing status is solved
2. If re-plug still unable to solve this problem, please take a screenshot for your current display and provide this screen for Thecus Support Team reference (support@thecus.com). OR simply submit a ticket at Thecus eSupport. (http://esupport.thecus.com/support/index.php?_m=tickets&_a=submit)


Which Thecus model is suitable for the video output procedure, such as N2800, N4800 series, N4510U series, N5550, N7510, TopTower series, N7710 & N8810 series, N8900 series, N12000V, N12000PRO, N16000V, N16000PRO.
