The following steps need to be followed and noted in your ticket before ordering a new Spectra Logic for the issues below.
No boot
disconnect all wires from the back-plane except the DC12 which powers the logic. If it boots up at that point you have a short somewhere in the cabinet.
Re-seat the Bios chips. This step may be necessary as we swap the bios chips when replacing the logic. The bios chips are needed to for the logic to boot.
23.12 after power cycle
Verify the NVRam Battery is connected.
Verify the battery is producing 3+ volts from Red to Black. We have had some batteries only produce 1.7v
Run the NCFI tool as there was a firmware update for the logic pertaining to the NVRam Battery.
No video to Topper
The game needs to have the following:
OS 21.2 or newer
bios 112.N
Follow these steps.
Plug the Topper Display-port cable in to the video card in place of the main monitor and see it anything shows up. This is to ensure the topper and cable work and are not disconnected.
Reboot a couple times.
Notice: the topper doesn't like to load after a ram clear some times. Its hit or miss. Just try rebooting a couple times.Pull the power plug from the power supply count to 10 plug it back in and power up comes on ever time.
Try the top port instead of the bottom one and repeat steps 2 and 3 again.
Re-seat
the BIOS Chips and restart at step 2.
If you have following all these steps and it still doesn't work make sure to note that info in your ticket. Upload a Game config picture to prove you have the correct OS and BIOS. Grab logs and be ready to send them to the TAC agent when they ask for them.
