Just updated no issues. Flip switch 8 plug in jump drive. Turn on and off ya go

no problems here

I have plenty of Sterns, never seen/heard of this before.

Grab a new CPU board while you can get a free one

No problem here, sorry you got a bad one

If it doinks, then hangs, the game is likely not recognizing the file format on your drive. Did you unzip the file before moving it to the drive? Is the drive formatted FAT32? Have you ever done an update with the drive? Does your AC/DC recognize the drive and allow you to scroll through the binary (.bin) files on the drive in update mode?

Stern is going to ask you these questions before they send you a new board. The no DMD the first time may have been a fluke. You may indeed have a bad board, but you need to do a little more troubleshooting before you call Stern. Make sure it's the board and not your drive.

There was another MET (I think) owner on here that had a problem with their boot ROM. Meaning their game worked fine, but it would not boot from the boot ROM so they could do an update.

I believe their game was behaving differently and would hang when it was trying to load the boot ROM information. They never mentioned the DMD going out. You might want to take a look at your boot ROM and make sure it looks like it is seated correctly on the board.

Pulling and re-seating a ROM (or even replacing a ROM) is much easier and less down time than replacing the cpu board.

Good luck, keep us all updated with their response.

This is not a Metallica issue. It's a corrupted boot rom. I had a Spider-Man in my shop last week with the same issue. Even with the USB not inserted, the screen doesn't have any display with the programming dip switch flipped. Game works normally otherwise. It should be fixable by burning a new boot EEPROM.

HERE IS THE FIX

I had this same issue. Once I flipped dipswitch #8 and restarted the machine, the DMD was blank and the game was unresponsive. If I moved the switch back, everything worked. I called Stern support and over the course of several emails, they had me do some tests and ultimately it was a bad EPROM. Once I changed the EPROM, the update worked perfectly on the first try.

Of course, Metallica uses special EPROM software. It requires version 1.0. Most new EPROM's come with version 3.1.

Here is the thread about needing version 1.0 on your EPROM (aka Boot ROM)

Here is a link to purchase the right EPROM for Metallica. Be sure to select version 1.0.

Even though my game was years out of warranty, Eddie at Stern support still took the time to help me identify the issue. I really appreciated that.

Also, special thanks to @Snakesnsparklers. He helped walk me through the issue as well.
