Profilux digital power bar.

[Aqua-Digital]

Hi

This can be two things

1. interference caused most likely by ballasts close to the power bar
2. water damage.
3 damage to data cable

1. Please check location of high voltage items to the power bar control line

2. If the power bar has been subject to high humidity or water incursion all manner of things can go astray.

3. Check the integraty of the data cable.

New PCB's are available cheapily.
