What make are the ones that are failing? What brand of lamps do you use? Do you have surge protectors on the booth panels?

The projectors must have all gone in about the same mtime so they are all failing close together.... The new rectifiers are not cheap, something like $2850 USD each.

The rest have been fine. Mark  |  IP: Logged
