Hisense TV Problems | 10 Common Issues & Easy Fixes In 2025

Hisense TVs have become one of the most popular budget-friendly options in the smart TV market. Their 4K UHD and QLED models offer great features at affordable prices, making them a solid choice for streaming, gaming, and entertainment. However, like all smart TVs, Hisense models can sometimes run into problems whether it’s a black screen, Wi-Fi not connecting, sound delay, app crashes, or random restarts.

This guide explains the most common Hisense TV problems and how to fix them step by step without needing to call a technician. Let’s go through everything you need to know.

1. Hisense TV Won’t Turn On

One of the most common complaints from Hisense users is that their TV simply won’t power on. You press the button or remote, and nothing happens no light, no logo, just a blank screen.

Possible Causes

• Power outlet problem

• Faulty power cable or adapter

• Internal board issue

• Remote sensor malfunction

Fixes

1. Check the Power Source:
   Plug another device (like a phone charger) into the same outlet to confirm it’s working.

2. Reset the Power Cable:
   Unplug the TV for at least 60 seconds, then plug it back in firmly.

3. Try a Different Outlet or Power Strip:
   Sometimes surge protectors can block power.

4. Check Remote and TV Button:
   Try turning it on manually using the physical power button.

5. Factory Reset (if it turns on partially):
   If the TV shows a logo but freezes, press and hold the reset button (found on the back) for 15 seconds.

If the TV still doesn’t respond, it could be a faulty power board in that case, contacting Hisense customer support or a certified repair center is best.
