Good work Bon, so the issue was faulty FCU? Was it the indoor board or supply fan motor?
The issue is the main power supply going into the FCU. He ran a separate power source temporary powering that FCU.
Thanks you so much! You're good men.
Welcome

So the power wire feeding that indoor unit was shorted to ground?
Hi Mr Bon, your video is very helpful. Could you please guide me how to ban indoor units, VRV4 has 6 indoor units, 1 indoor unit is to be disconnected from the power supply for repair, for the remaining 5 indoor units to still operate normally. Thank you so much for your support!
After disconnect indoor , reset outdoor power supply and long press return button.

Hello Mr Bon.
Why 2 of 5 indoor units does not have voltage?
I checked the supply til the branch and I have voltage.
I have to open the units to look the PCB.
there is probably something wrong with the high voltage side of the PCB?
Thanks for you support!
Check indoor fcu incoming power supply
