The Blackmagic Design Spares - ATEM 2 M/E Panel - Cable Set is a comprehensive internal wiring kit designed for the legacy 2 M/E Broadcast or Advanced Panels. Because these panels are physically large, they rely on a network of internal "veins" to carry power and high-speed data between the different M/E rows and the central logic board.
Replacing a cable set is often the final step in troubleshooting "ghost" errors that a PCB replacement didn't fix.
What’s Included in a Full Cable Set
-
High-Density Ribbon Cables: The wide, grey multi-pin cables that connect the Left and Right Section PCBs to the Center Master PCB.
-
FFC (Flexible Flat Cables): Extremely thin, paper-like cables used specifically for the LCD menu screens and "Scribble Strip" displays.
-
Power Distribution Harnesses: Heavier gauge wire looms (often color-coded red/black/yellow) that carry DC voltage from the internal power supply to the various boards.
-
Grounding Straps: Short, braided, or green-jacketed wires used to bond the various metal chassis components to prevent static buildup.
When to Replace the Cable Set
-
Intermittent "Flicker" Issues: The panel works fine until it is bumped or moved, at which point an entire bank of buttons or an LCD screen cuts out.
-
Pin Corrosion: In humid or coastal environments, the gold or tin plating on the tips of the ribbon cables can oxidize, leading to "data corruption" (garbled text on screens).
-
"Creased" or Pinched Cables: If the panel was previously opened for repair and a cable was pinched between the metal standoffs during reassembly, it can cause a partial short-circuit.
-
LCD "Lines": Vertical lines on the display are often caused by a microscopic crack in the FFC (Flexible Flat Cable) rather than a failure of the screen itself.
Technical Installation Note
Repair Level: 3 (Moderate). 1. ZIF Connector Caution: The FFC cables for the displays use ZIF (Zero Insertion Force) sockets. You must flip the tiny plastic gate "up" before inserting the cable. Forcing a cable into a locked socket will strip the silver contacts off the cable.
2. Cable Routing (Dress): Broadcast panels are packed tightly. You must follow the original "pathing" of the cables. If a cable is routed over a heat-generating component (like a voltage regulator), the insulation may eventually melt.
3. The "Click" Test: For the larger grey ribbon cables, ensure the plastic "ears" on the side of the socket click into place. A partially seated ribbon cable can cause "phantom" button presses where the switcher thinks you are hitting buttons you aren't touching.
4. Static Management: Cables act like antennas for static electricity. Always ground yourself before handling the internal looms.
Diagnostic: Cable vs. PCB
-
It's the Cable if: You can make the problem appear or disappear by gently "wiggling" the wire while the panel is powered on.
-
It's the PCB if: The problem is constant and unchanging, regardless of physical movement or cable reseating.
Pro-Tip: Reseating Before Replacing
90% of "cable failures" in ATEM panels are actually just loose connections caused by vibration during transport in a flight case. Before buying a new set:
-
Open the panel.
-
Unplug each ribbon cable.
-
Clean the tips with a specialized electronic contact cleaner (like DeoxIT).
-
Firmly reseat them.
This simple maintenance task often fixes "dead" buttons and flickering screens for free.
