Replacing LED bulbs on a small LED Sign

Postby B1gRed » Thu Aug 20, 2015 12:18 am


I have very limited circuit and electrical knowledge. I bought a small "PIZZA" LED display sign from a garage sale. I want to replace the small LED bulbs with 5mm LED bulbs for it to be brighter. I have put in the new LED bulbs in exact the same way but I can only get a section to turn on. Please see attachment for pictures. Please help!

Might be you need to check with the wiring and its design before you place the new LEDs in the same position.
