If no image appears, verify the resolution jumper or LVDS cable orientation. Documentation & Schematics
Power supply boards contain high-voltage capacitors (up to 450V) that can hold a lethal charge for days. Always discharge the main filter capacitor using a 10kΩ/5W resistor before probing or installing.
If you're not confident in your ability to flash the firmware or handle delicate internal components, the most reliable course of action is to have the installation performed by a professional technician.
Once the indicator light stabilizes or stops blinking, disconnect the AC power plug, remove the flash drive, and restart the unit.
