Earlier this year I got a CFTBL with a functioning hologram mechanism (lamps+motors) but a completely faded hologram.
Thank y'all pinsiders who has shared different ideas and posts on hologram fixes.
I've combined a lot of those and have the following working in my machine.
I first laser etched an image of the creature on 1/4" acrylic at the public library.
I had to bend the bottom of the existing hologram frame wider to accommodate LED strips on the bottom.
I've removed the existing hologram and plate and will leave the motor disconnected.
The 12V halogen lamp was moved to the front of the light baffle in the cabinet for accessibility.
I bought 2 matrix kits from Comet pinball for 12V. There's an adapter that fits in the 12V lamp socket in the game.
12V lighting strip
The 12V green LED strips are positioned so light shines upward through the acrylic.
The existing frame has holes the wiring can feed through.
I used Comet's matrix wiring to connect the 2 LED strips via a long wire to the lamp.
The parts for all this run under $30, maybe less.
