GE LOGIQ E9 Video Card Repair Service (DAC-BA04 – No Video Output / Black Screen / Display Failure / Image Output Loss)

The GE LOGIQ E9 ultrasound system uses a dedicated video processing card (DAC-BA04) to handle image rendering, digital-to-analog conversion, and video signal output to the monitor. This board plays a critical role in displaying real-time ultrasound images generated by the beamforming and image processing system.

Failure of the video card will directly result in loss of display or severe image output abnormalities.

Common Fault Symptoms

Our professional repair service covers all typical GE LOGIQ E9 video card failures, including:

• No video output (black screen on monitor)
• System boots normally but no display
• Intermittent or unstable image output
• Flickering or distorted display signal
• White screen / blank screen issue
• Image frozen on startup logo
• No signal detected by monitor
• Display works after repeated restart (intermittent failure)

Technical Overview (Video System Function)

The DAC-BA04 video card is responsible for:

• Converting processed ultrasound image data into video signal output
• Managing digital-to-analog display conversion (DAC function)
• Sending image data to system monitor via video interface
• Synchronizing display refresh with image processing engine

Failure in this module results in loss of video signal even when system is fully operational internally.

Related Board / Part Information

Common related identifiers in LOGIQ E9 video/display subsystem:

• DAC-BA04 Video Processing Board (main video card)
• Video interface / output controller circuit (varies by revision)
• Display communication interface board (system-dependent integration)
• Back-end image rendering output module (integrated GPU-like function in system architecture)

📌 Note:
GE LOGIQ E9 video architecture may vary slightly by revision (BT / XDclear platform versions), but DAC-BA04 remains the core video output processing module in most configurations.

Common Root Causes

• Video output IC failure or DAC chip malfunction
• GPU / image rendering pipeline corruption on video card
• Power rail instability affecting video processing circuit
• BGA solder fatigue due to thermal cycling
• Signal transmission failure between CPU and video card
• Firmware or initialization failure of display subsystem
• Connector oxidation or poor contact on board interface
