Trying to fix a display issue on my Simpsons DE, which is causing the 1/4A fuse to blow. Two power supply boards have been attempted so I'm concerned the issue is on the display board and likely these chips per research. I *really* don't want to rebuild the high voltage section several times over to determine it's something on another board.

Does anyone have any working pulls (or junk working boards) from any manufacturer that has UDN7180's on it? Price is of the essence as I really don't want to source these from some chinese knockoff knowing what additional damage that could do.


EDIT: OOOPS can someone move this to marketplace wanted?

Thanks in advance!

For $22. shipped you can have a Williams Taxi display board that was working before it became a parts donor. There are 3 UDN7180A chips. Paypal is okay.
 
Thanks Bob! I might take you up on that, but now that I have the display off, it seems that at some point DE changed the UDN7180s for a standoff PCB w/ a bunch of transistors and resistors -- maybe due to supply issues? So, as it stands my Simpsons actually doesn't use UDN7180s. However, I have a taxi w/ display issues that I haven't touched yet. I'll definitely keep this in mind as the price is certainly fair.
