00:00Did you know a genuine Samsung TV remote from the parts shop is $38, and the fancy smart
00:05touch ones run $76?
00:07A cheap universal at Best Buy is $15.
00:10People buy those every week because a clicker stopped changing the channel.
00:14Ten seconds with a camera you already own, you find out if that remote is actually dead,
00:19or if you're about to spend $20 to $80 on a plastic stick you never needed.
00:23Here is the part that should bother you.
00:25Half the time it was $2 of batteries and a cotton swab.
00:27The other half, a white crust on the springs was blocking the juice, and the remote was
00:31still firing a beam you cannot see.
00:34I have used this test every time someone in my house swears the remote died.
00:38I'm not driving to the store for a $38 OEM clicker until the phone says the old one is silent.
00:44By the end of this, you will know the camera check, the contact clean, the battery spring
00:48tweak, the pencil trick that recarbons warn buttons, and the one modern remote that fails
00:52this test on purpose because it is not using infrared at all.
00:55That last one is how people bury a perfectly good solar cell clicker.
00:59Your old-school TV remote does not talk with radio or Bluetooth.
01:03Almost every standard TV, cable box, soundbar, and streaming stick remote uses infrared light,
01:08same family as a heat lamp.
01:10Pulsed in a code, the TV understands.
01:12Your eyes cannot see it.
01:14Your phone's camera sensor often can.
01:16Point the nose of the remote at the lens, press a button, and watch the screen.
01:20A white, purple, or flickering flash at that little LED means it is firing.
01:25No flash while you mash buttons?
01:27It is not sending.
01:28Flash is there, but the TV ignores you.
01:30The remote is alive and all about, and the problem is line of sight, the TV's IR window,
01:36the wrong input, or a universal that never got the right code.
01:39Fresh batteries first if you have a pair sitting around.
01:42Open the camera app.
01:44Face the remote's nose at the lens, 5-15cm away.
01:47Press and hold volume or power.
01:49Look at the phone screen, not at the remote.
01:51Dim the room a notch if you are squinting.
01:53Do not stare into the LED.
01:55You will not see anything with your eyes anyway.
01:58Now the phone quirk.
01:59A lot of rear cameras, especially on iPhones, have a hard infrared filter.
02:03Sony's own support note says,
02:04Get the remote within about 2 inches of an iPhone camera.
02:08Or you may see nothing even when the clicker is screaming.
02:11If the back camera is silent, flip to the selfie camera.
02:14That front lens often has a weaker filter, so the flash shows up.
02:17If both cameras on your phone show nothing,
02:19borrow a second phone before you declare the remote dead.
02:22One android in the junk drawer has settled more arguments in my house than any store receipt.
02:27Still no flash with fresh batteries and a phone that should CIR.
02:30Pop the battery cover.
02:31White crust.
02:33Green fuzz.
02:33Dark residue on the springs.
02:35That is leaked battery chemistry sitting there like an insulator.
02:38Dip a cotton swab in isopropyl rubbing alcohol.
02:4170% or higher.
02:42And scrub until the metal looks like metal again.
02:45Stubborn crust gets a dab of white vinegar on a swab.
02:47Short contact.
02:48Then alcohol again to rinse the acid off.
02:51Then let it dry fully.
02:53Do not flood the board.
02:54Do not scrape the plating off with a knife.
02:56While you're in there, look at the spring.
02:58If it is flattened, the battery is barely kissing the contact.
03:01Which is why the remote works if you smack it and dies when you set it on the couch.
03:06Gently bend that spring out about a millimeter.
03:08That is the trick that saves remotes people already through in a drawer.
03:11If this is already useful, subscribe.
03:13It is free.
03:15Members get the longer tests I keep off the main upload.
03:17The sticky button recarbon and the bluetooth remote that fools the camera are next.
03:22If you are comfortable opening the shell.
03:24Screws hiding under a label or the battery door.
03:27Or clips you ease apart with a plastic pry tool.
03:30Wipe the carbon or metal pads on the circuit board with alcohol.
03:33Then flip the rubber button pad and wipe the black conductive pills on the underside.
03:37Finger oil, soda mist, and dust sit on those pills.
03:40And the button stops completing the circuit even though the IR bulb is fine.
03:44Let it dry.
03:45Snap it back.
03:46Camera test again.
03:47If a button still feels mushy after that wipe.
03:49Take a soft 2B pencil.
03:51Not a hard H pencil.
03:52You want the graphite.
03:54And color the contact face of the worn pill like you are shading a map.
03:57Thin.
03:57Even coat.
03:58That.
04:00Graphite is conductive enough to complete the circuit again on a lot of old rubber pads.
04:03Let it sit a minute so it is not smearing.
04:06Reassemble.
04:07Camera test.
04:08If the pill is torn or missing, this will not grow a new one.
04:11Then you are in replacement pad.
04:12Or new remote territory.
04:14Flash on the phone.
04:15TV still ignores you.
04:17Point straight at the dark plastic IR window on the front bezel.
04:20A few meters out.
04:21Nothing between you and it.
04:23Bright sunlight and some LED bulbs dump enough infrared into the room that the TV's receiver gets confused.
04:28Close the curtains.
04:30Or kill the lamp and try once.
04:31Move the other remotes off the coffee table so you are not talking to the soundbar by accident.
04:36If this is a universal, confirm it still has the code for that set.
04:39The camera already told you the clicker is alive.
04:42You are aiming, not shopping.
04:44Infrared also bounces.
04:45A white wall or a light ceiling will ricochet a healthy beam around a corner.
04:49A dark wood cabinet eats it.
04:50If your cable box lives behind a solid door, that is why the remote died the day you closed the
04:55cabinet.
04:56Leave a gap or bounce off the wall behind the TV before you spend $10 on an IR
05:01repeater.
05:01Now the modern trap.
05:03A lot of Samsung solar cell and smart remotes pair over Bluetooth once the TV is on.
05:08Infrared is only for waking a TV that is fully off.
05:11Point that remote at your camera.
05:13MASH volume.
05:14And you can get no flash at all.
05:15Because volume is not using the IR bulb.
05:18The remote is not dead.
05:19It is on a different language.
05:21Samsung's own test still says look for a colored light when you hold power.
05:25Power is the IR left over.
05:27If power flashes and volume does not, you are holding a Bluetooth remote, not a corpse.
05:32Pairing lives in the TV's remote or Bluetooth menu.
05:35Do not throw a $76 solar cell clicker in the trash because the camera stayed dark on the volume key.
05:41While the TV is still on, you already own a backup.
05:44On a Samsung, open the SmartThings app, add the TV, tap the device, and an on-screen remote shows up.
05:50Volume, mute, home, back, arrows. Free.
05:54It needs the TV on the same Wi-Fi.
05:57It will not help if the set is stone dead with no network, which is why you still want the
06:01IR test for the physical clicker.
06:02It will get you out of a lost remote night without a $15 universal.
06:06This same camera trick works on a lot of AC remotes, soundbar remotes, and older stereo clickers that still use
06:12IR.
06:13If the window unit stopped answering in July, do the 10-second test before you order a $30 HVAC remote
06:20with a part number you have to guess.
06:22If the remote took a swim, pull the batteries immediately.
06:25Do not power it.
06:26Dry it for days with real airflow.
06:28Not a sealed bag of damp rice is your only plan.
06:31Then fresh batteries and the camera.
06:33Water plus leftover voltage is how you turn maybe into a corpse.
06:37And do not mix old and new cells in the same bay.
06:40The weak one leaks first, and that is the crust you just scrubbed.
06:43If this stops you from tossing a remote that still had a beam in it,
06:46send it to whoever was about to check out a $38 clicker.
06:49Take care, and I will see you in the next one.
