OK then.
Looking closer at the boards image it looks like each side of the backlight tubes goes through these devices to a common connection, maybe ground, such being the case I suspect that they are mov varistors not caps, probably so if 1 or more backlight tubes fail the devices conduct and prevent the others from becoming unbalanced current wise, hence balance board, if they definately are caps then it wouldnt make sense for them all to go to one common, you cant see the other side of the board or the connectors properly so this might not even be the way its configured.
I dont think I can offer much more assistance.
