On my Whitewater, the left lamp board is much brighter than the right board, so I metered them and found the left is 11.4V and the right is 5.43V. Chase lamp board is clean, no burns, caps look good. Possible the bridge rectifier failed or should I be looking at something else?

can you measure the voltage that is comming out of the bridge ?

Common problem on these boards is the bridge rectifiers fail.

I will try to measure bridge voltage tomorrow morning. Good to know that the rectifiers are the common fault spot.

RESOLUTION for those looking through the archives, I replaced the rectifiers and the board is working great again.
