Hisense Roku TV Blinking On and Off: Fixes
It’s really annoying when your Hisense Roku TV starts blinking on and off. This usually means there’s a problem with the power supply, a software glitch, or the TV is too hot. First, make sure the power source is reliable and check if there are any updates for your TV’s firmware. If your TV keeps blinking, it could be getting too warm. Try placing it in a spot with good airflow, away from sunlight or heat sources. Also, make sure all cables are plugged in tightly.
Looking at how the TV blinks can tell you what’s wrong. If it blinks once, it’s likely a power issue. But if it blinks many times, the problem could be more serious, like with the mainboard or the backlight. For instance, two blinks might mean a small problem with the mainboard, and four blinks could point to an issue with the backlight’s wiring.
Try turning the TV off, then unplug it for 30-40 seconds, plug it back in, and turn it on. This can often fix small issues. If it doesn’t stop blinking, you might need to reset the TV to its original settings. Remember, this will delete any settings you’ve changed. If you’ve tried all these steps and the TV still blinks, it’s best to get help from a professional to avoid damaging your TV further.
