We hear about remote problems from two different kinds of TV owners. One group has an infrared remote that stopped responding overnight. The other has a Bluetooth voice remote that won't reconnect after a software update. This is common on sets like the U7K, U8K, and U9K lines. The fix is different for each case, which is why battery-swap advice alone often isn't enough.
The Quick Camera Test: Is It the Remote or the TV?
Before you try any fix, find out which part is actually broken. Point your phone's camera at the front tip of the remote. Press any button while you watch the screen, not the remote itself. Most remotes send an infrared flash that your eyes can't see, but a phone camera sensor can. If you see a flash, the remote is sending a signal and the problem is on the TV's end. If you see no flash at all, even after fresh batteries, the remote itself has failed.
If the camera test shows no flash, no amount of battery swapping will fix it. For Hisense TV owners, the HiRemote app turns an iPhone or iPad into a working remote over your home Wi-Fi. It usually pairs in about 30 seconds, with no new batteries needed.
Fix 1: Replace or Reseat the Batteries
Start with the obvious fix, since it solves most cases. Remove both batteries and check the metal contacts inside the compartment for dust or a thin white crust, which is corrosion. Wipe the contacts dry, then insert two fresh AAA batteries of the same brand and date. Mismatched batteries, one old and one new, cause more intermittent failures than people expect.
When this won't help: you already ran the camera test above with fresh batteries and saw no flash. That means the remote's internal circuit has failed, not the batteries. For a full walkthrough of Hisense-specific causes, see our Hisense remote troubleshooting guide.
Fix 2: Clear the Line of Sight to the Infrared Sensor
Most TV remotes are infrared. That means they need a straight, unblocked path to a small sensor window near the bottom of the TV's front edge. Soundbars, decorative trim, and even bright sunlight hitting the sensor directly can block the signal. Move anything sitting between you and the TV. Close curtains if sunlight is the issue, then try the remote again from a few different angles.
When this won't help: Bluetooth voice remotes don't need line of sight at all. They connect wirelessly rather than with an infrared beam. If your remote has a microphone button, skip this fix and go to the Bluetooth re-pairing step instead.
Fix 3: Re-Pair a Bluetooth Voice Remote
Bluetooth voice remotes occasionally drop their pairing after a TV software update installs in the background. On Hisense's Bluetooth remotes, hold Home and Back together for 5 seconds to force the remote back into pairing mode. Wait for the TV to confirm the connection on screen before pressing anything else.
When this won't help: if your remote has no microphone or voice button, it's almost certainly infrared-only. This step won't apply. Check our Hisense Bluetooth pairing guide for the full process and what to do if re-pairing fails twice in a row.
Fix 4: Restart the TV Instead of the Remote
Sometimes the remote is fine and the TV's receiver has simply frozen. Unplug the TV from the wall, wait roughly a minute, then plug it back in and try the remote again. This clears a frozen receiver without changing any of your settings or losing your channel list.
When this won't help: the TV won't power on at all, even after being plugged back in. That's a power issue, not a remote issue, and it needs a different troubleshooting path.
Fix 5: Replace the Remote With a Phone App
If the physical remote is lost, cracked, or confirmed dead by the camera test, a phone-based remote app is the fastest replacement. It's free to download. For Hisense TVs, HiRemote connects over your home Wi-Fi. It covers VIDAA, Android TV, and Hisense's Roku-platform sets, plus the H65, H75, and H85 4K ULED lines. It handles power, volume, channel navigation, and smart-TV menu navigation. It also includes a full keyboard for typing streaming app passwords instead of hunting letters on screen.
The app is free to download and holds a 4.4-star rating from 1,600+ App Store ratings. An optional yearly subscription unlocks extra touchpad and playback controls. Check current pricing on the App Store listing before you subscribe.
When this won't help: your phone and TV need to be on the same home Wi-Fi network. Very old Hisense sets running VIDAA 3.0 or earlier don't expose the network control needed to pair at all. If your TV isn't a Hisense model, check your TV brand's own listing in the App Store first. The pairing method differs by manufacturer.
If your Hisense TV runs on the Roku platform specifically, there's also a browser option. The free online Roku remote works from a phone or laptop with no app to install. You just need the TV's IP address from its network settings.

Frequently Asked Questions
Why is my TV remote not working?
Most TV remote failures come from dead or mismatched batteries or a blocked infrared sensor. Voice remotes can also lose their Bluetooth pairing. Start with a fresh pair of matching AAA batteries. Then use your phone's camera to check for an infrared flash when you press a button. If you see no flash with fresh batteries in place, the remote itself has failed. It needs replacing or substituting with a phone app.
How do I fix a Bluetooth remote that won't reconnect?
Hold Home and Back together for 5 seconds to force the remote back into pairing mode. This works for most Bluetooth voice remotes, including Hisense's U7K, U8K, and U9K models, after a software update interrupts the connection. If the remote still won't pair, restart the TV first, since a frozen Bluetooth receiver can block pairing from either side.
Can I use my phone as a TV remote?
Yes, most smart TVs support a phone-based remote over the same home Wi-Fi network as the TV. For Hisense TVs specifically, HiRemote turns an iPhone or iPad into a working remote with power, volume, channel, and app-launch controls. It pairs in about 30 seconds. For other brands, check that manufacturer's own App Store listing first, since the pairing method differs between brands.
Does unplugging the TV fix a remote problem?
Sometimes — unplugging clears a frozen receiver inside the TV, which can look exactly like a dead remote. Leave the TV unplugged for roughly a minute before plugging it back in, then test the remote again. If the remote still doesn't respond after a restart, the problem is more likely the remote's batteries, sensor, or pairing. The TV itself is probably fine.
Is there a free remote app for Hisense TVs?
Yes, HiRemote is free to download on the App Store and holds a 4.4-star rating from 1,600+ ratings. It covers Hisense's VIDAA, Android TV, and Roku-platform TV lines, with an optional paid tier for extra touchpad and playback controls. The free tier covers the core functions most people need: power, volume, channels, and app shortcuts.
