Hello all,

Thanks for the help with the other questions I asked for my BTTF. While it is a fun game indeed, I am more-or-less convinced it is not playing right. Both the sounds seem off from what I have heard on YouTube, as well as the the DELOREAN lights on the upper playfield do not seem to follow the game (lights are either always on, flash, and do not light (with no flash) when the LCD is spelling out the word). Could this be a bad ROM? If so, would getting a new EPROM possibly fix it?

Thanks!
 
Hello!

Anyone have an idea on this? I REALLY would like to get it worked out...

Thanks!

Hey Sam,
you got a BTTF?? Man, I guess we both got lucky. I'm obviously a newb to pins as well, but yes, I think the corresponding letter should light up for DELOREAN. Like, if you hit the ramp twice, the letters D and E should come up I think. I'll have to take a look again. I also thought for awhile that something was wrong with mine because two of the Huey songs never seemed to play, but it turns out I just wasn't hitting the right targets. I just got new rubbers for mine and cleaned and waxed the playfield...it makes A WORLD of difference play wise. Good luck man! Send some pics!

Thanks!!! It is a fun game and I feel lucky to have one.

From what I have seen, the DELOREAN in the back should light each letter individually when the ball foes through the ramp. Yet, my BTTF is not doing that as I see little to no variation in lighting when targets and ramps are hit. I really would like to figure out what is wrong.

May I ask what you used to wax the playfield? As for rubber rings, the ones on my BTTF seem good as the ball can really get moving from time to time!

Thanks again!
 
I cleaned everything with Novus 2 and then used Turtle Wax carnauba car wax. I put on two coats. I was really nervous to do it because I've never done it before but it was a pretty easy job to do and really made a difference. I also bought 3 new pinballs...my machine is fast as hell now! I hope you can figure out the delorean letter issue.

Hello all,

I wanted to let you all know that the BTTF has been fixed. Yea! It turns out there were several things wrong including a newly leaking capacitor and a driver problem. Also, one of the sound chips was either a lesser version or bad for, after replacing the chip set (the main and sound board EPROMs), the sound appear to be correct now.

Thanks again all!

Good thing you fixed that leaky FLUX and got rid of the guy in the life preserver who keeps stalling his car!
