Dim Clock LCD on Jenn-Air wall oven

[Longbow]

While replacing caps on the display board used to be a great idea, keep in mind that even with a working display pcb, the VFD displays wear out and dim with age. There is nothing you can do other than to replace the VFD tube itself - it is NOT an LCD. Good luck finding just the VFD...that's when you get to consider replacing the entire assembly.
