Hi Guys, I got lucky and found a Walking dead LE NIB a couple of weeks ago. I upgraded code, and it worked great! After playing I noticed an audio resistor was fried as pictured.

Stern tech support is down for Covid and they don’t seem to reply to email so I overnighted a replacement SAM Cpu / audio board from this place:

I installed it today and pulled the rom chip from the old board and installed the same way.

When powering on the machine the new board has a green power led but I get nothing on the display. I checked the dip switches and they are all correct. I also tried flipping the upgrade code switch to on with the usb stick installed with latest code and still nothing. The playfield only has one red light lit up by the prison toy. Anyone have any ideas? Maybe I missed a step? Never had to do this before but it seemed pretty straightforward.

Thanks guys!
Kris

I forgot to mention that before I swapped the cpu board the game worked perfectly. Screen worked, just the Audio broke after putting in the topper with likely bad power tap. I took it completely out and game worked fine until I swapped board.

Good advice, I reached out to mezelmods and they said they are looking at helping. I wish I could get in contact with stern! That’s what I tried at first but the 1800-kickers number is down for Covid. I emailed them last week and crickets still. Anyone know anyone at stern I can email? Don’t want to go any further down the rabbit hole without some help. Thanks again!

Yes I got a NIB from Troy at Vidgameseller. Also got Metallica LE NIB and Iron Maiden NIB. He is the best!

Ok I’ll try that as well. Thanks for the tips, the new board looks identical with all part numbers and revisions matching. Figured I missed something because I am used to working on spike and spike 2. First experience with SAM, seems a little more fragile.
