27" LCD backlight driver board us in Jersey Jack Pinball's The Hobbit pinball machines.
This driver board was reportedly also used in JJP's Pirates of the Caribbean & The Wizard of Oz pinball machines, but the manuals for those two machines do not confirm or deny this.
JJP reference #15-0021-01, #15-0021-00, #15-000021-00 & #15-000021-01.
