Laboratory Findings: 6 Ways to Fix Hulu on Sony Bravia
Required for this Verification: Sony Bravia Remote, Access to “My Account” on Hulu.com, and a stable 15Mbps internet connection.
Method 1: The 60-Second Deep Power Reset
This is the most successful fix for a frozen Hulu logo.
- While the TV is ON, pull the power plug directly from the wall.
- Press and hold the physical Power Button on the TV frame for 30 seconds.
- Wait 1 minute, then plug it back in.
Simple Wording: This drains the “ghost” electricity that keeps the Hulu app stuck in a logic loop.
Method 2: Removing the Hulu “Identity Token” (Fix for P-DEV320)
If you see a DEV error, your TV’s “ID card” is old.
- Log into your account at Hulu.com on a phone or computer.
- Go to Account > Manage Devices.
- Locate your Sony TV and select Remove.
- Restart the Hulu app on the TV and sign back in.
Result: This forces Hulu to generate a brand-new security key for your Sony TV hardware.
Method 3: Forcing a “System WebView” Update
Sony TVs use an internal engine to draw app graphics. If it’s old, Hulu will lag.
- Open the Google Play Store on your TV.
- Search for Android System WebView.
- If an “Update” button is visible, click it immediately.
Method 4: Manual DNS Re-routing (Fix for RUNUNK13)
If Hulu is slow to load ads or movies, your internet provider is taking a “long path.”
- Go to Settings > Network & Internet > WiFi.
- Select your network and click IP Settings > Static.
- Change DNS 1 to 8.8.8.8 (Google DNS).
- Restart the Hulu app.
Method 5: Disabling “Energy Saving” (Fix for App Crashing)
Hulu requires a lot of RAM. If the TV is in “Eco Mode,” it may kill the app to save power.
- Go to Settings > System > Power.
- Turn OFF Power Saving Mode.
Method 6: Clearing the Individual App Data
- Go to Settings > Apps > See all apps > Hulu.
Select Clear Cache, then select Clear Data.
Note: You will need to type your password again, but this removes any “junk” files that are causing the app to crash.
Common Sony Hulu Questions & Expert Solutions
Q: Why does Hulu buffer while Netflix works fine on my Sony TV?
A: Hulu uses a different “Handshake” for its advertisements. If your router has a strict firewall or ad-blocker, Hulu will pause to wait for the ad to load. Netflix does not have this specific technical hurdle. Try Method 4 (DNS change) to fix this.
Q: Will resetting the Hulu app delete my profiles?
A: No. Your profiles and “My Stuff” list are stored in the Hulu cloud. Resetting the app only cleans the temporary files on your Sony TV hardware.
