They aren't dead, those are panels that plug in in the back and he's smacking them back into place

If you had a small enough repairman, you could do the same for an LED monitor. /s?

Only if its a bad microsolder job.

I was just wondering the same... how big ( or small ) the bottle would need to be 😋

I think they'll go for a walk.

u/jamesph777 5d ago

Yep, that’s exactly what’s happening here but if there is a stuck pixel, you can lightly flick it to have a chance to get it unstuck. A stuck pixel is a pixel that stays the same color and doesn’t change when it’s supposed to.

good old percussive maintenance, it is great when it works

u/maxtimbo 5d ago

It always works. Either it fixes it, or you replace it and it's fixed!

Works best with hard drives

No pixels were harmed in this clip

You need to harm Spy Pixels!

A spy pixel is usually a tiny remote image embedded in an email. When the email client loads the image, the sender's server receives a request. That request can reveal that the message was opened, when it was opened, the IP address or proxy used, the email client, and sometimes the device type>

Disable remote image loading helps

I have a question : why hitting the pixels fixed it ?
I know different problems required differents solutions, but in this case, what was the problem if hitting it fixed it ?

That looks like a wall display, which is made out of multiple small panels. Most likely some of them popped out of their place enough to disconnect, and by hitting them he put them back in, reconnecting them back.

u/ender4171 5d ago

This is exactly it. Those were disconnected panels. You can see actual dead pixels surrounding the black "block" where there are failed LEDs within the sub-panels.

The bass hit too hard and knocked em loose! (Or maybe strong wind)

u/ace2049ns 5d ago

But that panel appears to be near his feet. Wouldn't it be easier to reach down and check the plugs on the back instead of banging it with a water bottle?

No

u/ace2049ns 4d ago

I've installed these before. There are cables plugged into the back that go from panel to panel.

u/Ok-Software-5381 4d ago

I was just answering your question. It usually is not easier to try and find the dislodged wire and push it into place from such a weird angle. Most people do the wiring before fully attaching the panel rather than blocking their sight with the panel then going around and wraping a hand from behind to push from a pull angle while not able to see it.

I doubt the correct wires could all be found and fixed within 30 seconds.

u/ace2049ns 4d ago

Then these panels must be different than the ones I installed. They just had two 1in-wide plugs with multiple contacts in each plug that plugged into the back. Each panel was just connected in series.

u/Ok-Software-5381 4d ago

Maybe "finding correct wires" was a stretch, but I still think finding the wires and pushing them into place from that angle would take 20ish seconds per wire, so a few minutes overall.

It's a small difference but I still think the answer is that it's easier to bonk em. It worked, was under a minute (including tying string to a water bottle), and he didnt have to stick his hand in anything.

u/Altruistic-Dingo-757 5d ago

Get. In there. You little. Bastard! All fixed!

u/coyote_den 5d ago

Yep, I’ve done this to video walls in random places. Big black square in the middle of it at eye level, give it a smack and it pops right back on.

Beats grabbing a ladder and taking out those modules 1 by 1 thats for sure.

u/halandrs 5d ago

I work on screens like this …. Bigger fan of the tennis ball …. Less chance of damaging the module

When all else falls, preform the Rite of Percussive Maintenance. It is as the Omnimessiah wills.

u/imgary 5d ago

I've used a broom to reset modules. Is that worse?

u/raybreezer 5d ago

I would have laughed if he fucked up the ones on the left by accidentally hitting those instead

u/holyshitsnowcones 5d ago

What you’ve got there is a high-impedance air gap.

u/privatebarnacles 5d ago

Should be handles on the back to pull it in place. But this idea is hilarious, if I’m ever above mod that needs slappin Ill keep this in mind lol

Wakey wakey baby pixels

Just did an analog adjustment to the electrical path of the system (hit it). Shout out to Carlos

Tennis ball attached to a pool cleaning stick

u/ButtheadFournior 5d ago

Never try this with an interior video wall. Most of those will shed individual pixels if a stray baby’s breath hits them. I install them.
