Hisense TV has many users and offers good quality and technology at a cheaper price compared to Samsung, Sony, and LG. Hisense TVs have excellent technology and quality and usually work well, but like all TVs, they may have problems.

If your Hisense TV won't turn on and flashes red, don't worry, many users have experienced this problem and this article provides solutions to troubleshoot and fix it.

Why is Hisense TV blinking red light?​

Many factors can cause your Hisense TV to blink red.

1. Power board failure

This is the most common cause of Hisense Smart TV blinking red. When your TV inside has a damaged capacitor, a fuse failure, or a burst internal component, it can cause the power board to fail.

Swollen caps and burnt capacitors are the most common causes of power board damage. Other causes may also cause power board damage.

2. LED backlight array failure

Another possible cause is the LED back array problem, although this cause is rare, we should not ignore it. When the LED back array fails, your Hisense TV may function normally, but the power button will flash red. For this issue, you need to contact the appropriate technician to solve it.

3. TV stuck in standby mode


When you use Hisense TV for a period of time, it may get stuck in standby, and the red light on the power button will blink. At this time you will not be able to do any operation to make it continue to work.

4. Bad power supply

Sometimes bad weather such as lightning can burn out the TV's circuit board, or problems such as damage to the power cord can cause a power shortage.

5. Wrong input source

When you use Hisense TV's port to access other devices, you need to select the correct input source. For example, if you use the HDMI port to access a device such as a game console, but do not select the correct HDMI input source, this will result in a Hisense TV error and may prevent the power from turning on.
