having done the snackbar mod v1 with el wire and without an extra power supplier your game system may be on the edge of having power issues. The screens take 5vdc which should not be an issue but the 12vdc for the el wire is the drain monster of power especially if you want a colordmd, backlit speaker panel and hologram mod under the playfield window.

a little history on the movie poster mod.......

for me I reworked the snackbar mod v1 and came out with a v2 design (which you just purchased) to solve the elwire potential issues and switched to leds.

as for the poster mod (large screen), I developed the original movie poster mod and then due to supplier issues and then a supplier change of screen I opted to cancel my design / production in which Sparky asked me if he could do a limited run of 23 (number of people on my wait list) of a larger screen with el wire which was a little different to my concept as it runs a video and not a photo slide show.
