Intermittent light can point to a failing module, driver, ballast, connection, or power issue.
2. Sections Look Dim
Uneven brightness makes the sign harder to read and can signal aging components.
3. Letters Are Dead
One dark letter changes the message customers see.
4. You Hear Buzzing
A buzzing ballast or power supply deserves a professional diagnosis.

Loose faces, cracked panels, shifted mounts, or water intrusion can worsen after heavy weather.
