I have a Gottlieb "Roller Disco" pinball machine that has dull displays. I've been told that there are ways to 'charge' the displays to brighten them. I viewed a video on You Tube, but the connection to the charging point is not on MY machine.

Can someone help me? Thank you.

Thanks for the info. I will try this one, too. During this past week I tried a similar solution by using 12v. I tried 30 seconds then up to 1 and a half minutes,...did this 2-3 times on each display. Definitely brighter but not as new. Orange grids did light up but some on YouTube say this is OK. Interesting how each person sees the solution differently. So, I printed the picture in the 'link' and will try soon.

OK...Tried the 'slower' system of "charging". 2 of 4 displays are still dull. Charging doesn't seem to work. New ones are not being manufactured. Refurbished ones are on Ebay. Anyone know if there is a reliable source? Thanks!
