Is your Hisense Smart TV responding slow, lagging in menus, or showing a Storage Space Running Out error? These are classic signs of cache and cookie bloat. Unlike a smartphone, a Smart TV has very limited internal storage. When temporary files from apps like Netflix, YouTube, or Prime Video pile up, the entire Tizen or Android kernel slows down to a crawl.

If your Hisense smart tv apps are not working or apps keeps crashing on your tv then you need to clear cache (internal memory) in order to fix these hisense tv issues. You need to navigate to apps section and select the application you want to clear cache and press ok on clear cache and data.
At asavvyweb, our technical lab led by Rajeshwari Chiluveru has verified that clearing your cache every 15 to 30 days is the best way to maintain 4K streaming performance. This master guide combines every verified method for Vidaa OS, Roku TV, and Android/Google TV models.
Why should you delete cache and cookies on Hisense TV?
Cache files are meant to help apps load faster by storing images and data. However, in our 2026 lab tests, we found that Corrupted Cache Bits create a Logic Loop. The TV’s CPU stays at 100% usage trying to read a damaged file, which causes the remote to feel unresponsive. Deleting these files flushes the RAM and forces the TV to rebuild a healthy index.
Method 1: Global System Cache Wipe (Android & Google TV)
This is the fastest way to speed up the entire interface.
Press the Home button and select Settings (Gear Icon).
Go to Device Preferences and select Storage.
Select Internal Shared Storage.
Highlight Cached Data and press OK.
Confirm the delete. This will instantly free up several hundred megabytes of system memory.
Method 2: Clearing Cookies and App Data (Vidaa OS Models)
If your TV is not an Android model, it likely runs Vidaa. The Cookies here are stored within the browser and app handshake logic.
- Open Settings and go to System.
- Navigate to Application Settings.
- Select Clear Cache or Clear Cookies.
- Note: Clearing App Data will log you out of apps like Netflix, so ensure you have your passwords ready.
