The worst thing is that people who throw away LCD TVs usually crack the screen when they dump them. Because they don't care. I found once 50" LED TV at the dumpster, and it had bad solder joint at power supply connector, when I fixed it, I saw the crack, and the crack probably came afterwards and the real reason for being in trash was just bad solder joint.

I suspect this "fell off the wall" We know it was powered when it fell, because the mains cable has been yanked, broke the connector off the pcb, and the L or N arc'd across as it was eventually pulled out which left the sooty smudge you saw first

Aaah no , if it’s been upside down all of the colour will have leaked out

That's still good as a light panel!

TCON is short for Timing Controller board. These boards re-time the signal from a standard source timing to the specific timing required by the panel. By timing we're talking about front porch, back porch, and vertical blanking timings. Standard timings have standard values, while the panel itself will have different values (but overall the timing is the same) so a TCON is mostly just delay lines and buffers and maybe a PLL if the total pixels per line or lines per frame is different. As the panel needs to run at the same rate as the incoming signal it's a fairlly lightweight process. (After all if it's 60Hz panel, it needs a 60Hz input signal, but the timing details can vary within those limits).

Quick tip for checking lcd screens. Use a bright light pressed up to the screen. It will help you see defects like cracks and bruises. In a pinch, you can use your cellphone led. The bright the light, the better. So a cheap $1.00 torch may not be best.

I reckon it took a fall and pulled the power out on the way down

There must be large sheet of polycarbonate or acrylic in there, and a large sheet of polarized film. Plenty to salvage and repurpose or play with.

Last time I found a cracked screen TV, I made over 100 euros selling the circuit boards on ebay, just sayin'.

I'm betting it took the damage in the dump room, which is sad. There's tutorials online to show you how to turn it in to a light panel. The lenticular lenses make the light straight on like it would be coming in a window. Great for 'natural' light in the bunker.

I'm in the U.S. and in this area we have bulk trash pickup twice a year where the city will haul away almost anything you put on the curb for free. I don't know much about fixing TVs, but I've brought home a bunch and gotten several working ones. The biggest one is a 60" Vizio with half the backlights burned out. I kept it with the intention of putting new backlights in (there's a video tutorial), but a set costs $80 and I haven't been able to justify the cost, especially considering that if I accidentally crack the LCD panel, I'll have wasted my money. Also, the backlights bruning out is apparently a common problem with that model as it supposedly sends a power surge when first turned on, which shortens their life. Next is a 50" Samsung, 4K TV, which seemed to work perfectly, but started glitching around the three hour mark. I haven't had the ambition to do much with it. I keep meaning to run it with the back off and a fan blowing on it to see if it's a heat problem. I have a 47" LG that works, but it has some moisture in the screen. I'm torn between trying to take it apart and see if I can wipe down the layers, or just letting it sit and see if it dries out on its own. I also have a 43" Vizio that works, but also has moisture in the screen. I have a 40" Toshiba that works great, but has one stuck green pixel on the screen. I have three 40" Samsung TVs that all seem to work perfectly. I have a 32" LG TV that had moisture in the screen when I got it, but which dried out and now just has a couple spots that are SLIGHTLY darker than the normal screen, but aren't that noticeable. I also have some smaller TVs in the range of 20" down to about 17". I recently gave away a 46" Seiki TV. It didn't have anything 'wrong' with it, but I didn't like the fact there was no way to turn off overscan. If the TV has a resolution of 1920x1080 and I set my computer to 1920x1080, I expect a pixel-perfect image, not one that's been enlarged and has the edges cut off. Many years ago, my friend and I found two identical TVs, about 60" or so. At the time I didn't want them, so he gave them to his brother. One had a bad power supply and the other had a cracked screen. He combined the parts and made one good TV out of them.

"That's not a TV, THAT'S a TV!"

Ironically I am watching this on my 2024 86" LG 4K TV which incidentally weighs 50Kg

If it has a loose connector its a tell tell sign that someone triped over the power wire and it fell to the ground

"bigger than my arm reach, check that out" .. dave continues to flex dem cheex

Let's be honest. This is a better outcome for a video. Othervise too many people would get jealous.

Maybe it fell off/from wherever it was mounted and the cable was ripped off in the process and when it hit the floor it got cracked?

I've seen exactly that damage before. It's fallen forwards and ripped the cable out. In think the usb was squiffy too. I was expecting the broken screen and sure enough. What a pain it is to repair, I'd need a bigger workshop!

There is still a way to use such panel for the artificial light. For all dark rooms, with no natural light, once the upper layers are removed it can bright nice light.

I wonder if the burn mark on the plug was some guy who after seeing the cracked LCD just grabbed the power cord and yanked it out in a fit of rage?

Maybe was wall mounted and it fell off. While falling the power cable was ripped off by the weight and the burn marks could be due to arching during Unexpected Rapid Disconnection :)

Just a few days ago, I unintentionally did a dumpster dive. I was transporting hundreds of wine glasses from one area of a venue for an upcoming sports event to another area; I just happened to look into one of the recycle bins which was beside a staircase I was standing near. I thougt what I saw was some kind of kitchen machinery. It was just laying there in the bottom of the bin; but on closer inspection it turned out to be a Sony TC152SD tape recorder (from the late seventies), just lying there at the bottom of the bin. I wasted no time in picking it out and taking it to my locker. It's at home now (without power cable); I just have to figure out if it works, and if not, how to get it working. Beautiful looking thing. I salvage a couple of motors from a Standing fan yesterday, the ones where the fan head rotates horizontally so as to cover a wide area; it that had been thrown into a giant skip at work, that and some sort of power switch for connecting I don't know what. Gotta do my research. But it's fascinating how easily things are thrown out over here (I'm in the UK) Anyway; I have to wonder what they got as a replacement.

RSVP that TV. I do wonder which came first, the broken connector or the cracked screen. Judging by the skid mark on the connector, I'd say that was the reason for them getting rid of it, then they cracked the screen when they dumped it or moving it. Sadly, I can't be impressed with these "big" LCD TVs. We used to have a pair of 150" units in our old studio, which were pretty much the largest LCD panels ever made (they were prototypes, never manufactured or sold commercially). No idea what happened to them after we moved to our new studio, probably shipped back to Sony. Now we've got those huge video walls that are made up of the modular LED panels. The big one is about 15m long, so they blow away any TV you can get these days. Really impressive to look at, until you poke your head around back and see how much wiring and power goes into the thing. Makes you wonder how they ever got it working in the first place!

Damn, that´s big. I guess if it could float both Jack and Rose would fit on it 😛

Even when damaged, I wonder if screens this size have something useful inside. Large backlight diffusion layer for uniform lighting? Or something.

One of those portable power packs that you can power a tv would be good to take dumpster diving. That tv must have been a pain to get home.

Darn, I bet there weren't even any gold bars or $500k scopes under it in the dumpster either. Dumpster diving just isn't what it used to be. 😪

Fixed my last TV that went out with a used power board for like $35. It was a 42 or 45”…years ago. Still working.

I wanted to try to fix just _a_ TV recently. Found one on the local market internet thingy, it was 82 inch. Couldn't fit it in the car. Just getting it of the wall already risks a crack, because the TV flexes a lot. There was an issue with the connector to the leds, the leads were sooo thin. Also a little control IC went short on the power board. But lifting the panel up to get access to the leds went wrong, because of the enorm size of it. It cracked. It's just to. hard to handle, you need a frame with suction pads or something. The plastic is now my bench table top. The leds will be my bench lighting.... Insane amount of leds and power in the thing.

I've almost wrote good on ya Dave, but it turned into bloody Murphy in a sec. Mega-bummer! Screen sizes and weights are inversely proportional to their probability of a catastrophic failure, that's a new addition to the bloody Murphy law right there! 🙃

the injection mold for that back plastic must have cost half a million

Reminds me of the 70+ inch tv that was put up in the coffee area in our old office. The two idiots mounting it to the wall mount it only in the drywall and called it good, i warn them that it won't hold but they didn't care, it fell next night, brand new tv went into the garbage

Well, this was a rollercoaster :D

shine a bright light directly at the panel next time!! you will see the crack and save yourself the trouble, i agree with others and guess this either got cracked when getting tossed or fell off a wall/table while plugged in.

Hmm, looks like a screen I saw in a dentist over Norwest way - endlessly playing kids movies... The fish in the tank opposite must have developed square eyes.

I wonder if it were one of the "must destroy before throwing away" type of scenario. Seems like they might have just ripped the power cord off to try to "break" the unit. Maybe when they did it, it shorted something.

Likely that burn mark was just from a poor electrical connection on the plug, do that was likely all that was wrong with it originally.

Dang!....so close but so far! That would have been perfect for the new room at home.

"Bloody Murphy!", I must remember that one!

Absolutely gutted! I'm sure the screen was fine when it went into the dumpster room but got broken in there... Usually happens. People don't value things when they stop working so end up breaking something more important. I always try to offer help to local people who have something that's broken and tell them _"it's likely to be something simple and easily fixable"_ so they don't end up breaking it more. Such a shame!

You can use the TV's backlight for studio lighting for taking youtube shots. As always thanks for the video.

This guy has the best dumpster in the world.

The answer to that power connector would be to wire in a power cord (I recommend having it unplugged from the wall outlet while wiring it in, lol). Give it some strain relief and should be gtg. I'm sure most of us, if not all, have an extra power cord from either an old pc or monitor.

Good score we found a 72 inch but didn't know if it worked but took it home plugged it in n it did work looks like I'm at the movies I'm happy it was. a good thing we took it

When the back panel is wider than you are tall you know you've a big-assed TV.

They probably broke it when throwing it out.. I bet that plug was the only issue. lol... Oh well. At least now you don't have to carry it.

I immediately jump out of the chair.run to the tv and stretch the arms...😂

Ahh bummer!! Better luck next time! That thing looked like a futuristic security door when it stood up and you crouched down! My lastest find was a curved 34" ultrawide 144Hz monitor, the power connector was a bit loose but still working, and it was missing the external power supply!

Shove some bare wires up the clacker... the channel that just keeps on giving!

Thats it I'm moving to Australia

Legend has it this thing's huge. What a silly setup.

....... with the operational backlight, I wonder if you could use this as an 86" lighting panel?

Wouldn't the longest wire go to Earth? You want to keep that connected till the bitter end?

They can't all be perfect 😀

At least you tried. Cheers for that.

They throw away the best tech in Australia. Best you can find in Southern California is a 32” Sony Trinitron that requires 3 guys with back braces and a 1 ton truck to move.

That TV looks surprisingly light for its size. Try picking up an 80 inch plasma TV! It takes two people to lift it, and even then it's difficult.

The cracked screen was probably "post mortem" as it was being dumped, because "Why take care with handling, if it's already kaput?".

I have a feeling that you will soon find a discarded tesla in the dumpster room.

It might make a nice lighting panel? !

I've got a few spare boards for that TV and they all work

I would still apply a video signal just to make sure it's dead; often the screen is blanked when no signal is present. I found a tossed LCD TV and despite the nasty crack, most of the screen was fine.

Nice softbox / lighting panel and surely someone out there needs a controller board / PSU? Nice find regardless...

I need a tv that big when i move into my new apartment

Sometimes ya win some, sometimes ya lose some!!

That’s not a TV, this is a *TV* …

The worst thing is, they probably threw it away due to the broken connector and the screen cracked in the process. It's insane how bad consumerism has gotten that people are just willing to throw away thousands of usd and not even bother to try to fix it... this was literally a 10$ fix (the 10$ is to buy the soldering iron to fix the connector)

You can actually get replacement screens for alot cheaper than its worth to buy the whole tv especially these days since diy repair is so huge you can get the screen for around $200-$250 and sell the tv for about $800 their 86" models from oldest to newest models still sell between $1000 and $5000 refurbished/new. I know this because i fix broken flat screens alot and resell.

I didn't pay for this TV, I'm not Dave picking this up from the dumpster, but I am still very disappointed that it's broken...

Use the backlight panel for something cool like , fake window or something

HELLO DAVE I live in Ipswich and when they have kerbside collections I quite often go and collect TVs from the kerb to dismantle for parts for a friend who sadly has just passed away. If you think that’s heavy try some of the older Plasma TVs they weigh a ton. Interesting but I see a lot of different brands of course the cheaper we’ll known brands are always in large numbers but in the last 2 collections I have yet to see an ALDI TV the BRAUHN brand. That would be in around 150 TVs in 4 yrs. Unfortunately you no longer see CRT TVs.

The closest I have come to that was a laptop with a broken screen of unknown tech. I think the cracked part was actually glass. I removed the broken glass and visually it worked but the touchscreen functionality was gone. So I'm wondering if the break is just cosmetic and potentially repairable with a big sheet of plastic, or does it usually damage it to the point it can't display an image at all?

Call Of Duty on that bugger!.... Sweet Bujeebus!!!😂

Probably would make a nice daylight ceiling light wit that surface

The Ali scrap value has to be worth it if nothing else ☺️

The backlight and its diffusers would make a pretty good 'window' for the bunker, you know. But for best effect, you'd want a 86" sheet of toughened 3mm glass to replace the panel.

There is strain relief on the metal flap that cable comes through.

2020 is pretty current

Bad luck there. Would have been nice.... Just imagine it as 4K microscope display.... SEE IF THE PCB ASSEMBLIES SELL ON EBAY OR SIMILAR, if still working these could be worth many dollars. Chassis may have scrap metal value too.

Pretty sure Northridgefix has had a lot of these in, he says they always die after a year, and it's a port issue (multiple traces break loose). Some are fixed from reflowing the port, but most require fixing all the traces. Maybe this can be an excuse for Dave to get a JBC nano?

"... a 2020 vintage" - wait, what? 2020 was 4 years ago! And at the end... yes, I was expecting something. Too good to be true.

use it as the best lamp you never seen , remove cracked screen then run it only for backlight , attached on ceiling

it would make a nice big wall light

What a bummer! You can even sell the LED strips if you feel like

I pickup a lot of samsungs for free on FB marketplace, couple of caps later, resold for 50-100 dollah. All these 2010-2018 seem to have cap issues, easy fixes.

65in visio found and repaired here in the usa ...was just a few LED s replace up and running ...it sucks working on theses things

I made skylight from RGB-strips, it copies the sky color outside with ESP-camera. With giant TV one could show clouds and stars and birdshit. It does matter if it is cracked, as roof windows tend to crack because of ice and snow. DIY Perks did something like that?

TV Prolly fell off the wall and cord was yanked out from the weight of the TV when it fell. the boards if good, can sell for ~75-100 each.

That crack was absolutely soul-destroying :(

Oh that's too bad, but at least no financial loss on your part!

I would not be in such a hurry to scrap the 86" TV myself. It depends on the crack/scratch. If the TV still works but has a deep scratch, I could use it as a monitor or kids room TV or remote or outside view. Lots of low quality display possibilities. If it is just scratched (that is what it looked like to me in your limited view we see, then you might even be able to buff it out. My point is think outside the box.

Curious how much a lew LCD screen would cost?

Super nice find, shame about the result. Cracks can be detected before doing any work by shining a torch on the screen. Biggest I've found is a 50 inch toshiba. The problem with it was the ribbon connections to the panels were broken. Still got it but will probably not bother bridging the broken ribbon connections. I'll remove the tcon and power board , sell them and dump the rest at the tip.

Big arc as it suddenly went open circuit on its way to the ground.

Cheers Dave " Bloody Murphy " lol

I estimate Dave's wingspan to be about a Turkey Vulture

Dave, No Cinderella story ending there, oh well perhaps another LG tv that needs all the boards replaced might come around or do you think these boards might willy nilly fit in another brand of TV? its all the same factory line just the badging and sw might be different

makes for a really nice light though

I'm the same I live in a very posh area of London England the things I find. TVs computers.

Is signs of something that smoked typically called an earny/burny (sp?) in Australia?
