How to Repair a White Screen
The first step in repairing a white screen is to identify the cause of the issue. Once you know what is causing the issue, you can begin to troubleshoot and repair it. Here are some of the most common ways to repair a white screen.
Check the Power Supply
The first thing you should do when troubleshooting a white screen is to check the power supply. If the power supply is faulty, it may be causing the white screen. To check the power supply, you'll need to unplug the TV and disconnect all cables from the power supply. Once the power supply has been disconnected, use a voltmeter to check the output voltage. If the output voltage is incorrect, then the power supply will need to be replaced.
Check the Main Board
If the power supply is working properly, then the next step is to check the main board. The main board may be causing the white screen if it has become damaged or faulty. To check the main board, you'll need to unplug the TV and disconnect all cables from the main board. Once the main board has been disconnected, use a multimeter to check the voltage levels. If the voltages are incorrect, then the main board will need to be replaced.
Check the T-con Board
If the main board is working properly, then the next step is to check the T-con board. The T-con board may be causing the white screen if it has become damaged or faulty. To check the T-con board, you'll need to unplug the TV and disconnect all cables from the T-con board. Once the T-con board has been disconnected, use a multimeter to check the voltage levels. If the voltages are incorrect, then the T-con board will need to be replaced.
Check the HDMI Port
If the T-con board is working properly, then the next step is to check the HDMI port. The HDMI port may be causing the white screen if it has become damaged or faulty. To check the HDMI port, you'll need to unplug the TV and disconnect all cables from the HDMI port. Once the HDMI port has been disconnected, use a multimeter to check the voltage levels. If the voltages are incorrect, then the HDMI port will need to be replaced.
Check the Video Card
If the HDMI port is working properly, then the next step is to check the video card. The video card may be causing the white screen if it has become damaged or faulty. To check the video card, you'll need to unplug the TV and disconnect all cables from the video card. Once the video card has been disconnected, use a multimeter to check the voltage levels. If the voltages are incorrect, then the video card will need to be replaced.
Check the LCD Panel
If the video card is working properly, then the next step is to check the LCD panel. The LCD panel may be causing the white screen if it has become damaged or faulty. To check the LCD panel, you'll need to unplug the TV and disconnect all cables from the LCD panel. Once the LCD panel has been disconnected, use a multimeter to check the voltage levels. If the voltages are incorrect, then the LCD panel will need to be replaced.
