Check the rest of the tombstones. The wiring that pokes in there often gets loose.
Make sure the lamp pins are in correctly. It's easy for them to pop out when the lamps are installed.
Make sure the ballast you installed is 2 lamp/120V
Check all wire nutted connections
I HATE flourescent bi pin tube lamps/sockets BTW. I always seem to struggle with them. Give me 8 footers any day :thumbup:
