Shopping out a CFTBL- got to the bowl # 86 lamps. Noticed one socket is missing from board. Also one socket does not light up. Checked continuity on pins through traces to all bulbs and they check fine. Measured voltages at sockets and they are measuring 7.3 except for the socket that wont light which is 4.6 as well as the board traces where the socket is missing. Could it be the voltage is insufficient to light the bulb and the reason that this socket as well as the missing socket are reading 4.6 points to something wiring wise and not with the bowl light pcb itself? Just trying to figure out where to look. I assume I can replace the # 86 socket on this board?
