Black Screen/Frozen Screen/Screen Stuck at Boot Logo

Before you start make sure you have: Small screwdriver (1.5mm / 1/16"), SD-to-USB adapter, access to PMB server

 Step 1: Power Cycle the Screen

This fixes most freezes and boot failures. Try this first.

  1. Remove the screen from the wall.
  • Loosen the grub screw a few turns. They sit on the side of the frame that holds the screen on.
  • Older screen models (silver frame around the glass) also need the screen frame unscrewed from the wall.
  1. Remove the gray metal protective box from the back of the screen. Take off the 3 small nuts.
  2. Unplug the power connectors at the top left corner of the top board. They use black and red wires. If there are 2 sets, unplug both.
  3. Wait 5 to 10 seconds, then plug the power back in.
  4. Check that the system boots normally and responds to touch and RFID cards.
  5. Reinstall the screen in reverse order.
  6. If the screen still freezes or won't boot, go to Step 2.

Step 2: Rewrite the Micro SD Memory Card

Call PMB support at (888) 259-5125 first. Let them know you want to troubleshoot the SD card.

Remove the card

  1. Remove the screen from the wall, the same way as Step 1.
  2. Remove the gray metal protective box from the back of the screen.
  3. Unplug the power connectors. Power must stay off for the rest of this step.
  4. Remove the Micro SD card. It sits along the right edge of the bottom computer board, just below the network wire connection.

Never remove or install the Micro SD card while the power connectors are plugged in.

Rewrite the card using an SD-to-USB adapter

  1. Insert the Micro SD card into an SD-to-USB adapter.
  2. Plug the adapter into the PourMyBev server.
  3. Support will open the HDDRawCopy program PMB and write the card. This may take 5+ minutes
  4. Remove the adapter once it hits 100% and take the finished Micro SD card back to the screen.

Reinstall the card

  1. Reinstall the Micro SD card into the beer wall screen.
  2. Plug the power connectors back in.
  3. Check that the system boots normally and responds to touch and RFID cards.
  4. Reinstall the screen into the wall.

If this does not fix the issue, the Micro SD card may need replacing. Use a card that is at least 8GB, Class 10 speed or faster.
