Why Do Onn TV Problems Happen?

While inexpensive, Onn TVs are generally reliable. But like any electronic device, they can experience technical glitches or failures over time.

Common causes include:

• Faulty hardware components – e.g. bad capacitors
• Outdated firmware leading to software issues
• Connectivity problems with cables, WiFi, HDMI ports
• Damaged speakers or audio circuits
• Issues with the TV remote and sensors
• Power surges frying electronics
• Overheating due to poor ventilation

Many problems are easy to diagnose and repair yourself with basic troubleshooting. Other times you may need assistance from Onn support or a professional repair technician if internal components have failed.

Troubleshooting Onn TV Issues

Below are the most common problems reported with Onn televisions and their possible fixes.

Onn TV Not Turning On

If your Onn TV will not power on at all when you press the power button on the set itself or the remote control, try these troubleshooting tips:

• Make sure the TV is securely plugged into a working electrical outlet. Unplug and replug all connections.
• Inspect the power cord for any damage. If the cable appears faulty, replace it.
• Press and hold the power button on the actual TV set for 30+ seconds to force a hard reboot.
• If the above steps did not work, do a factory reset via the small pinhole reset button on the TV’s rear panel. Use a paperclip to press the button in for 15-30 seconds until the TV reboots. Set up the TV afterwards as if new.
• If the TV still fails to start up, the problem is likely an internal hardware failure requiring professional service.

Onn TV Stuck on Logo Screen

If your Onn TV gets stuck on the logo splash screen when booting up and never actually loads the Smart TV interface, try:

• First, unplug the TV power cable and press & hold the power button for 60 seconds to discharge residual electricity.
• Check that all your HDMI connections are properly inserted. Faulty HDMI cables or loose connections can disrupt the boot process.
• If you have a separate streaming box or media player connected, disconnect all devices and see if the TV boots up normally without anything plugged into HDMI.
• Do a force reboot by pressing and holding the physical Reset pinhole button on the TV rear panel for 10+ seconds using a paperclip until the logo appears again.
• Reset your TV to factory settings via the Settings menu (see directions below).
• As a last resort, call Onn support – a stuck logo screen is usually due to corrupt firmware or defective hardware.

Onn TV Keeps Rebooting Randomly

If your Onn television suddenly turns off then immediately turns back on repeatedly in a loop, try these fixes:

• Unplug all devices connected to your Onn TV via HDMI cables first. If the reboot looping stops, then one of those peripherals is the issue.
• Toggle off CEC device control settings on your TV under System > Control other devices. This can prevent connected devices from accidentally power cycling your TV.
• Perform a factory data reset. From the main System settings menu, select Advanced > Factory Reset. This wipes all saved preferences that may be corrupted and causing crashes.
• If random reboots still occur, speak to Onn support. There may be faulty capacitors, RAM issues or problems with the main logic board.

No Picture or Sound on Onn TV

• If the TV is on (lights or logo displaying) but screen is black with no menu showing or audio heard, first thoroughly check cable connections. If using an external box or device, change the TV’s input mode to match the port.
• Toggle between different HDMI inputs and cables to isolate the issue. Also directly connect the Onn TV to cable/antenna feeds to test.
• Try a force reboot – unplug TV for 2 minutes, press/hold power button 30 seconds, then plug back in.
• Reset picture/audio settings under the TV’s Settings menus or do a factory reset. Corrupt saved settings may be causing no AV.
• If new cables, input switching and resets don’t restore missing picture/audio, it’s likely a failed internal component like the LED backlights or sound IC chip. Professional repair needed.

Fixing Onn TV Picture Quality Issues

• For Onn TV picture problems like distorted images, fuzzy video or discolored video try adjusting your picture mode presets under Settings > Picture. Vivid, Standard and Movie modes optimize settings for different viewing needs.
• To manually correct distorted video, slowly calibrate options for brightness, contrast, sharpness, color saturation under the Picture menu.
• Ensure any external devices properly output video resolution supported by your Onn TV, like 1080p or 4K. Incorrect input signals can lead to AV distortions. Use compatible cables.
• For color issues specifically, toggle various HDMI ports to see if that helps. Also re-seat cable connections. Faulty HDMI ports or loose cables cause color problems with video sources.
• Still seeing fuzzy, distorted or black & white video? Could be faulty T-CON or mainboard failing so professional repairs may be needed.

If you have a black screen on Onn TV or blinking red light, check the provided guides.

Fixing Onn TV Sound Problems

• If your Onn TV has audio issues, first check the obvious stuff – make sure TV sound isn’t muted and volume isn’t too low. Press the physical Volume and Mute buttons on remote.
• Ensure correct audio output mode is enabled. Navigate to Settings > Audio > Audio Output and select Stereo, PCM, or Dolby formats. Auto detect can sometimes not work properly.
• Similarly, confirm ‘Volume Mode’ is set to normal under Audio Volume Mode adjustments. Toggle off any volume leveling options.
• Try a basic reboot by simply turning off and unplugging the Onn TV for 2 minutes. Power back on and test speakers.
• If above doesn’t restore sound, do a factory reset of your TV under Settings > System > Advanced System > Factory Reset.
• Still having Onn TV speaker problems after resets? Could be blown speakers or faulty audio processor IC. Time to get a repair quote.

How to Fix Onn TV Remote Issues

Common problems with Onn television remote controls include buttons not working, remote not being detected, short range and difficulties pairing.

Before assuming the remote control itself is faulty, do the following:

• Check remote batteries are fresh and installed correctly based on polarity +/- alignment. Dead batteries are the #1 cause of remote issues.
• Make sure you are pointing remote directly at the TV’s IR receiver window from no more than 20 feet away. Look for blinking IR light.
• Thoroughly clean remote button contacts with alcohol and cotton swabs – stuck buttons are a common reason for remote control failure.
• Also clean the IR transmitter window on front of remote with glass cleaner and cloth. Dirty sensors reduce IR range.
• Try pairing original remote again – go to Settings > Remotes & Devices > Pair new remote.

If problems persist, continue troubleshooting:

• Disable CEC HDMI device control which can disrupt remote functionality due to connectivity with other devices.
• Reset remote to factory settings if possible to clear any corrupted programming.
• Update TV and remote control firmware to latest available software since bugs often addressed.
• Use the Roku app on your smartphone or tablet to serve as backup remote if hardware buttons fail.
• Purchase a compatible universal remote or replacement Onn remote if all else fails. Easy replacement remotes start around $10-15.

Fixing WiFi Connection Issues on Onn TVs

Here are the steps to resolving difficulties connecting your Onn television to home WiFi:

• First, ensure WiFi router itself works normally with other devices like phones to isolate the problem is with the Onn TV. Reboot the router and Onn TV box if needed.
• Under TV network settings, delete old WiFi connections causing issues, then setup the wireless network again from scratch. Enter correct new password if changed.
• Check for firmware updates for Onn TV. Newer system software versions can improve connectivity.
• If connection drops or lagging video occurs randomly over a previously working WiFi setup, reduce interference. Move WiFi router closer to TV, check router band selection (2.4 Ghz vs 5 Ghz) or eliminate obstacles between the devices.
• During retries, toggle OFF and ON the ‘Connect via Wireless’ setting instead of just skipping option when going through network config wizard.
• As last resort try a wired ethernet connection instead or get mesh repeater node to strengthen WiFi signal to entertainment area.

Fixing Onn TV App Problems

• Force close a problematic app by pressing the Home button for 5 seconds then reopened. This clears any memory glitches.
• For sluggish or constantly buffering apps, check internet connection then reboot the Onn TV and router box. Then test streaming speeds to confirm no bandwidth issues interfering with apps.
• Delete then reinstall any persistently frozen or crashing apps. Corrupt local files often cause apps not to work properly.
• Clear the cache partition and data for buggy apps under System > Storage to wipe temporary files causing problems. Note this resets app login info and settings.
• Check for app software updates available from the Roku store. Also update the Onn TV system software itself. Recent upgrades could fix app bugs.
• If one app struggles but internet connection seems otherwise fine on the TV, delete then reinstall that singular problematic app to refresh coding.

Fixing Onn TV Randomly Turning Off

• Rule out physical remote control issues first. Confirm IR sensor unobstructed. Check batteries fresh; replace remote if damaged buttons stuck causing power signal to TV.
• Disable auto power options like Sleep Timers, Screensavers that blank screen or Eco/energy saver modes triggering premature shut off.
• If problem started suddenly, make sure vents are dust free and ambient temperature not too high. Overheating can lead to random crashes and reboots. Add cooling fan if placed in poorly ventilated cabinet.
• Connect devices to Onn TV correctly so CEC (Consumer Electronics Control) signal confusion does not occur. Try disconnecting HDMI inputs one by one to isolate interference from a problematic source item.
• Perform factory reset if you still suspect software related issues rather than hardware. Under Settings menu choose Systems > Advanced System Setting > Factory Reset.
