In some cases, replacing the backlight or the entire display panel may be necessary to resolve the issue.
How do I know if my Hisense TV’s flickering issue is caused by a hardware problem?
If your Hisense TV’s flickering issue is caused by a hardware problem, you may notice some distinct symptoms. For example, if the flickering is accompanied by a buzzing or humming noise, it could indicate a problem with the backlight or the power supply. Additionally, if the flickering is more pronounced in certain areas of the screen or is accompanied by a dimming effect, it could indicate a problem with the display panel or the backlight.
Other signs of a hardware problem include a complete loss of picture or sound, a distorted or discolored image, or a burning smell coming from the TV. If you notice any of these symptoms, it’s essential to contact a professional TV repair technician or the manufacturer’s customer support for further assistance. They can help diagnose the issue and recommend the necessary repairs or replacement.
What are the options for repairing or replacing a flickering Hisense TV?
