Judge Dredd lower GI burnt connectors (resized).JPG

#1 3 years ago

Hey guys,
Was hoping to pick some brains here. I noticed yesterday that My JD is missing some of the lower GI lights all of a sudden. I ran through the test menu and it’s one set the White-Yellow that’s not responding. Checked the plugs and nothing seems cooked.
Anyone have any other suggestions?
Any help is greatly appreciated.

Have a look at the 5 fuses in the lower left corner of the driver board. Pull out each one and use a meter to check them. Or one of the daisy chain wires has broken off the lamp sockets.

Also look for burnt connectors at J115, J120 and J121 on the driver board.

Hey guys,
Pulled and checked all the fuses and inspected each connector. Nothing. Any other suggestions before I pull the driver board?

AC power to the driver board for GI, left side of board, lower ? Power leaving driver board for that string ?

LTG : )

I just fixed my "lower" GI only outage on Judge Dredd last night.

I second to search for problems being connectors with a high probability at J120 and J121.

The pcb shares trace runs between both these connector so any resistance between both can cause issues. If not browned up at least reflow the pin solder and clean and reseat to see if something changes.

The Pinwiki has a good section on GI light troubleshooting https://www.pinwiki.com/wiki/index.php?title=Williams_WPC#General_Illumination_Problems
