Have 9 of them currently 3 are non working and came to me that way. Seeing i keep buying fixer uppers (even the ones that came working [supposedly all fixed] they give the appearance of being right but find out otherwise) yes there are general illumination issues,switches that some how don't work 1 out of 5000 times every so often. Really just depends on the day of the week the issues change . But i kinda expect that for games that are 25+ yrs old and were routed and not always taken care of as they should have. I fix stuff in runs but keep on playing them when possible. This helps in the trouble shooting. Kicker is just about the time the game is done i go and sell it and get another project.
