1）Regarding Adapter Temperature
It is normal for the power adapter to become slightly warm during use. A surface temperature between 30°C to 50°C (86°F to 122°F) is generally considered safe.
However, if the adaptor feels very hot to the touch, emits any unusual smell, or shows signs of discoloration or instability, please stop using it and contact us for a replacement or further inspection.
2）Regarding the buzzing noise from the power adaptor:
A slight humming or buzzing sound from the adaptor can be normal, especially when it’s running with low or no load. This is caused by the internal components such as coils or transformers vibrating slightly.
However, if the noise is loud, irregular, or accompanied by overheating, flickering, or a burning smell, we recommend stopping use immediately and contacting us for a replacement or further assessment.
Please feel free to send us a short video or audio clip if you’re unsure — we’ll be happy to assist further.
3）When the customer received the neon sign is not lighting up upon setup, one common cause could be incorrect connection of the plug to the controller. Unlike single-color neon signs, RGB signs have a 4-pins connector (four holes on one side, and four prongs on the other), which must be aligned and inserted correctly.
Please ensure the following:
The four metal pins from the controller are inserted into the matching four holes on the RGB connector.
Each pin must be aligned with the correct slot — they cannot be inserted randomly, as this will prevent the sign from functioning.
The connector should click or fit snugly when fully inserted.
