New thread kinda the same as the wpc driver board I repaired for a fishtales a couple of weeks back.
Generic WPC Driver board repair thread
Connectors will all be inspected and if needed repaired.
Major connectors are the J115 J120 J121 that usually have the most damage.
The J121 J120 headers and connectors will need to be replaced.
J118 header looks fine, but connector is burnt. Will replace header as well, as it has been stated the headers oxidize and create more resistance.
J118 is also the 12v feed for the mini playfield driver board and motor... Such as in indiana jones.
Here are the pics I have so far of the damage.
This is repairable, j121 pin 1 has me worried as it is loose... That means the pad underneath is most likely... Fucked... So I may have to wrap wire around the pin, solder it to the pin, and make a wire jumper from j120 to j121 bypassing the trace... No biggie and it will likely not be seen
There is a through hole trace on j115 that has to be checked also, as the top of the trace supplied a triac with voltage, it is easily overlooked, but checking for continuity on that top pin to the transistor will show if the mod is needed or not. Been there done that.
Once I repair this board, another member has another driverboard from his wpc getaway that has gi lights out, and I believe is the same issues. That would be my third wpc driver board repair.
It must be stated, the pads fucking suck on these boards. I am not looking forward to doing a cap kit when the time comes on one of these.
