Nascar
Stern, 2005I just picked up a NASCAR and when I powered it up all of the G.I. lights are flashing. If the coin door is open all the coils fire as well And fuse if 21 quickly blows. There is a rottendog driver board and I think has all new game roms. The display does not work at all but it’s a working display. Any suggestions on what to look for?

I closely inspected the chips underneath the batteries and I do not see any alkaline damage. When I went to take you 212 out I noticed that some of the legs were not seated. I seated everything properly and I still have the same problem. When I boot the machine up, part of the display comes on momentarily which I did not do before I did anything. Any suggestions now?

Had a similar problem on a Nascar and it was the RAM chip. If you turn the game on and then push the reset button on the board and it boots, it might be that. Took forever to figure it out.
Can't remember the location of the RAM chip, but your game rom at U210 should have that little window covered or light can erase or corrupt it.
When I press the reset button I still have the same problem. Could my problems be caused by the ram on U210? Perhaps it was compromised already. Also the ram that was on U 212 was not seated properly but I seated properly.
It's been over 5 years since I fixed mine, but it was a headache. If your game rom is compromised, it might cause that I guess.
I found a cpu rom inside and it was the original rom that plugs into u210. It had all the legs bent and crushed but I straightened everything out and put it in the game and it comes on and does not flash the lights or fire coils any longer. I can't start a game but its cycling through the lights properly. The screen just stays locked on *STERN PINBALL NASCAR* but hopefully the rom is just damaged and a new one will do the trick. I will update when I get the new rom. Thanks for the help.
Quoted from Don44:I can't start a game but its cycling through the lights properly.
Have you tried coining it up or setting it to free play?
Yeah, I figured that when you the said the screen stays locked on at Nascar Pinball. Well, at least you are making progress.
Try the new game rom and see what happens. As long as it is now booting, the RAM may not be an issue on yours.
The newer game rom has a different display rom than the original. If you go back to the original code, you will need the correct display rom too.
Nascar is a game that you want to be on the latest code, because the last revision had code to deal with the trough issues. If the older Rom boots, then your current rom probably got corrupted.
Quoted from Don44:Thanks, which rom is the display rom?
Don, I had this exact same problem. I have to go with RAM chip as well. I took out the L chip and put in nvram. After doing that I was able to get it to boot. If that doesn't work I'd try checking continuity with that socket.
Good luck
It should be the ROM on the display board. I unfortunately sold the game so I am going off of memory.
I got a new rom, Nascar 4.50 and put it in and I still have the same results. Machine comes on and says on the display reads *STERN PINBALL NASCAR* After a few seconds it properly cycles the lights. Service buttons do not work. The display rom installed says u rom o 401. What display rom should I be using?

Feels like you need to start looking at the RAM chip.
After installing nvram and changing the ROMs, I still have the same problem. It turns on and says stern pinball NASCAR on the display. Then goes into cycling lights mode. The thing that spins on the truck activates as well. I tried swapping out the DMD controller board as well. Could a problem with the sound or voice Roms possibly cause problems like this? Any other ideas before I send out the board for repairs?
