Comen STAR8000C Patient Monitor LCD Backlight Inverter Board INV1506 (2p bigger)

Comen STAR8000C Patient Monitor LCD Backlight Inverter Board INV1506 (2p bigger)

 
 
► Brief Introduction
 

This component is the backlight driver board for the STAR8000C patient monitor, part number INV1506. It contains two lamps and provides a stable high-voltage AC power supply to the LCD display, driving the screen backlight to illuminate. It is a key component for the device's image display.

The circuit board is secured inside the device with two screws. Its two ends connect to the main board and the display screen respectively, ensuring the backlight drive of the display.

The driver board has two high-voltage transformers with warning labels to prevent accidental contact damage during maintenance.

 
 
► Features

1. Adaptive Brightness Adjustment

It can adjust the screen brightness according to the device's instructions. Whether the lighting in the ward is strong or the lighting in the ICU is dim, it can adjust to a suitable brightness that is neither glaring nor reflective, ensuring normal brightness during use.

2. Ensure Uniform Screen Brightness

The circuit board uses an independent high-voltage drive circuit to drive the two lamps of the display screen separately, achieving uniform brightness output across the upper and lower areas of the screen. This ensures clear and color-accurate ECG waveform and data display.

3. Multiple Circuit Protections

It integrates multiple protection mechanisms including short-circuit, overvoltage, and overcurrent protection. When a lamp ages and breaks down, or when an interface becomes loose and short-circuits, the driver board immediately cuts off the high-voltage output and sends a fault signal to the main board to prevent high-voltage backflow from damaging the device's main board.

4. Reduce Electromagnetic Interference

The optimized filtering design significantly reduces the ripple and noise of the high-voltage output, avoiding screen flicker, wavy patterns, and other interference. It also reduces electromagnetic radiation, minimizing interference with the device's ECG signal acquisition and ensuring the accuracy of monitoring data.

►FAQ
 

Q1: Is there a risk from the high-voltage transformer on the driver board? What precautions should be taken when replacing it?

A1: It generates thousands of volts during operation, posing a risk. Before replacement, the power must be disconnected and the device's capacitors must be discharged. Avoid direct contact with the transformer pins and high-voltage output interface during operation. Wearing insulated gloves is recommended.

Q2: The screen backlight flickers, and it still flickers even after replacing the backlight tube. What could be the cause?

A2: It's most likely due to aging of the filter capacitors on the driver board, causing excessive high-voltage output ripple and preventing a stable current supply to the backlight tubes. Replacing the driver board will solve the problem. It's also recommended to replace the aging backlight tubes at the same time to avoid further damage to the driver board.

Q3: What does the warning label on the driver board mean? Can it be removed?

A3: The label is a high-voltage warning, reminding repair personnel of the high-voltage danger present to prevent accidental contact. It's not recommended to remove it. The label also provides insulation protection, preventing dust and liquid from entering the transformer pins and reducing the risk of short circuits.
