- Interchange starters, lamps or ballasts to establish
whether they are defective.
- If they are not defective, check the internal wiring,
especially that connected to the lamp holders.
- The snap-on connections of the wiring can be detached
by means of a paperclip.
- Premature blackening of a tube end points to a defective
starter or a wiring fault.
- A burned NTC resistor or overheated wiring points to a
wiring fault at the connecting block.
- The acrylic sheets can be cleaned with a moist cloth and
some washing-up liquid.
Avoid the use of alcohol, alcohol-based cleaners, petrol,
acetone or abrasives.
These substances can cause irreparable damage to the
