The stains aren't on the outside. So what's going on inside? Wanna help support this electronics fool? / thatelectronicsfool www.paypal.me/theworkbenchYT ko-fi.com/thatelectronicsfool
Cellulose in the Polarizer is breaking down.. it creates a corrosive gas that attacks similar components.. replace all the cellulose layers the others won't be far behind. This happens to most Cellulose film products that are more than 20 to 30 years old depending on the storage conditions.
If that is the case, unfortunately I'm not hoarding, errr.... have any inventory of any other LCDs I can take the sheets from. It's gonna have to remain this way for now. The 24" one I took the one sheet from doesn't have any other sheets I can use.
@@ThatElectronicsFool The issue with other old monitor parts is they are aged as well.. Best to use new Polarizer Film.. New stock is readily available online and is very cheap.
I think most people could it with a few tools and supplies, just gotta give it a shot and have a bit of patience. I had never actually tried replacing stuff like this before, I have only taken broken LCDs apart in the past. Thanks for watching!
Very interesting. So I looked it up, the only thing that moves me away from thinking it's the same as vinegar syndrome is that it doesn't smell like acetic acid. Didn't think of making a mention of it in the video, but the affected area smells a lot like cinnamon rolls to me.
Doesn't look at all like the vinegar syndrome. Besides the smell not being there (as mentioned by @ThatElectronicsFool), the vinegar syndrome has almost an oil spill effect as opposed to these 'burn' marks.
I think the LEDs are for whats called tally light, the frosted long ellipses above each screen indicates ; Red= on air. Green=on preview (selected on video mixer preview bus).
I think it's dead bugs getting cooked inside. I have dead bugs in my computer monitor. Terrible construction. Mine is not smashed just dead so oblong black pixels. Maybe someone pushed the LCD panels trying to "massage" away the bugs :D Good job on replacing the sheets. Maybe these displays could come in a box with a large TALLY light on the back.
Ah yeah, tally light in the back makes sense. As for the stains being due to bugs, I looked at a lot more areas than I showed in the video, but none of it had any visible evidence of bug material. Unless they were some really microscopic things that caused the rest of the material around them to start delaminating over time when they decomposed.
Definitely looks like rust. But then it begs the question of what those sheets are made of. I'm gonna guess whatever it was made of got oxidized or chemically degraded somehow. So I concur with t1d100, some kind of burn, possibly exposure to high power radio waves, perhaps it was used in a radio or tv station.
Possibly. I asked my buddy who gave it to me. Said it was originally in a server room and was supposed to be used to monitor that video signals were getting to the server that was recording whatever was being sent to it. Said nobody ever really went into the room to check it, and so it was determined to be underutilized and got taken out.
That was an excellent and fascinating repair, well done! 🙂 BTW, looking up that unit online I see assorted sites selling it for between 2.5K and 3K Euros ...........
Thanks! And yes, I had no idea how much these went for when I saw the pic of it in the text message. To think it was just gonna end up getting thrown away...
It can't be image burn because that usually appears on the display but that is very very strange I was wondering the reason maybe for the glue and stuff in the scholastic material used in some sort of vibration Like a lorry or some sort of industrial vehicle🤔🤔🤔🤔🤔🤔
maybe it was in a Broadcasting station each light could represent a Pacific camera that's being used in a studio maybe not who knows it just seems like that🤔🤔🤔🤔
After asking about it, it turns out it was installed in a server room where it was meant to be used to make sure video signals were reaching the server that was recording whatever was being sent to it. Apparently it was rarely ever actually accessed for the intended purpose, and so it got taken out.
Similar spot shape makes me think not bugs. I'm guess radio, or microwave, burns.
roach poop

That's true. I'll have to look into it. Thanks for the suggestion!
Very nice repair! I couldn't do it! Wow!

Seems like googling the term of this phenomenon is kinda difficult with many vague searches.
The term you're looking for is vinegar syndrome on lcd.

Inventory Enthusiast :) subbed right away, great video.

Definitely leaning towards believing it's been caused by some sort of transmitter in the vicinity of where it was used.
Looks likea build up of heat has degraded whatever that layer is made of. These sort of screens are left on 24/7.

@@ThatElectronicsFool Sadly there's an enormous amount of such waste around the world, and it's usually for tax write offs.
So freaking weird... The mystery of the weird brown stains... We shall never know. Great fix tho

Cool video that looks like bugs
looks like humidify got in there. water demage - rust
thats roach poop
That looks like nicotine stains.
And if that was in a rack with a ventilator it could be that it was sucked in and pushed trough.
