Working on restoring a WH20. Everything was working great and I was just about to put the playfield back in the cabinet when I noticed the inserts were not blinking (specifically the rafts on are what I noticed first). The GI is fine and so are the flashers.

I thought they were not working at all until I looked closer and realized the inserts are blinking, but they are very weak. Here’s what I’ve done so far:

Checked for continuity on fuses
Reseated the connectors at the board
Installed the daughter power drop power board to see if that would help

Nothing. Can anyone please help? Much appreciated. John

I'd grab a meter. What voltage at the sockets ? What voltage leaving the power driver board ? What voltage power going to the driver board.

First try and figure where power is dropping.

Yea check your grounds , wiring , and pins. Sometimes Your wires and connections have something that looks good but can have a bad connection . Check your continuity with a meter and your diodes.

Thanks everyone. It was the OCDLED board. Once I pulled that out it worked perfectly.
