The "how it looks afterwards" was really helpful Mr... Thank you!

I figured this was a cap problem based on my problems with a 2008 LCD TV monitor...replaced those in 2017 and its still going strong in 2024

in my frustration i punched the screen then loads of dust and fluff came from underneath the IMAC, works great now but not reccommended, mine is 8 years old and was way slow, not any more!

I think only the early intel iMacs use magnets to hold the screen on. Later models got screwed with just adhesive, because Apple. Thanks for reminding me about the battery and paste.

hi

doesn't work

Thank you

is this common to AOC monitors?

Did it work for anyone !? -.-

Mine was glued and the screen broke. Be cautious

Bet you generated a few extra jobs for yourself from the 'gently pry the screen with a screwdriver part.

the backlight of my 2010 27" imac looks exactly the same!

just what i was looking for...... especially the part that showed how the computer looks if the left bank has failed...thanks... very much appreciated.

I can also confirm baby wipes work perfectly for this. Had 3 Macbooks with screens so bad from this problem I couldn't even give them away. Had all 3 looking brand new in about an hour. Credit to our man in the video above though, for looking for solutions and sharing them with the greater audience so we don't all end up emptying our pockets to Apple. Thanks and keep doing what you do. 🙌

iMacs with adhesive tape are a nightmare to service, someone without experience working on mobos will likely break a clip or something... thanks, Apple, for a nightmare design.

I had been suffering from a fan that was making a lot of noise for some time. Finally opened up the 2019 iMac 27", carefully blew all the dust (and it was a lot) out with a compressor, disassembled the fan, took it apart and cleaned it nicely. I did not hear the iMac anymore and the fan runs quietly in the background. I taped the monitor at 6 points with strong black tape because then I can clean it regularly. Not pretty but effective.

Hi, I came across this video while doing a search. Currently I'm using a 2017 iMac. I'm trying to get a dust cleaning, but it costs $100. should i do that?

I managed to clean it with both Listerine and Lysol. Aproximately one hour of elbow grease later the screen looks like new. Bought an antiglare protective and voilá!

mais il y a 3 ventillateur dans un imac lol

The best way to remove the coating is to use a toilet cleaner. 10 minutes, all gone. 😂

I choose the hard way as always and went for screen disasembly to solder the connector. Tryed to save aluminum tape, you cant just cut it and seal with electrical tape. When removing white plastic that holds connector i broke led lamp, just remove led strip and leave white plastic in place. Will order led strip now.

What is the monitor model name?

Go to any Home Depot, Lowes, etc. and buy a quart of Denatured Alcohol. Apply it onto a clean paint rag, microfiber cloth (even a paper towel will work). Rub it vigorously onto the screen and do process over and over until all coating is gone. This process is GUARANTEED to work. Clean the screen with glass cleaner (Windex, etc) to leave your screen perfectly clean. Good luck.

Baby wipes are the clear winner. Took less than 10 minutes to remove the whole coating. My baby wipes contains: Aqua, Glycerin, Gluconolactone, Potassium, Sorbate, Sodium Cocoampoacetate, Allantoin, Sodium Benzzoate, Pathenol, Dimethicone, Calcium Gluconate, Citric Acid.

WaSTE OF TIME. THIS WAS AN OLD ASS IMAC FROM 2010.

Hello and thank you for sharing your experience. For my part, I tried the first solution of breaking the connector and trying to solder directly but it did not work. So I was patient and disassembled the whole screen to make this repair. The difference is that I didn't use thinner wires and connected the whole thing to the screen via heat-shrink tubing. I directly soldered the flat cable to the printed circuit board, having glued it beforehand with a cyanoacrylate dot. I took the opportunity to do this operation on each side and here is a wiring complement for the right side: D1+ D34- D2+ D35- D3+ D36- And for those who would like to test each LED circuit, you should apply 36V DC voltage per 12 white LEDs in series and allow about 1A.

3m machine polish compund 39009 works for me in my apple watch coating

Nah

Baby wipes does the job with not much effort. Tried it myself and took me about 10mins to remove the coating off my entire 15" screen. I tried the listerine method first, and gave up since I was rubbing for about 30 mins and I was able to remove the coating only on a very small section of my screen, so I searched for other methods to try. At first I thought it was a joke but I have baby-wipes around and decided to try since baby wipes did not seem to me not a drastic method to try. I was shocked and amazed how easy and well this worked.

This video may or may not be what I’m looking for so I was going to ask a few questions. But first, I scanned the comments to see if they were already answered. This guy answered ZERO viewer questions! What is the point in posting a video like this if you’re not going to engage with your viewers and answer questions?! That’s stupid!

Did I miss something? You just replaced every capacitor? No diagnostic or what? I'm confused

What if I buy that compound alone, could I use it for the whole screen?

Listerine does work, as does rubbing alcohol. I found kitchen degreaser spray a little faster than those even. Moisten the cloth, not too wet, cos you need some friction. Use a fingernail behind the cloth in stubborn areas. If it seems to stop working, moisten a fresh area of the cloth to use. The fibres seemed to get clogged and stop working after a short time. I was using a chux wipe. Finally, no spots! Just a bit glarey, but doesn't bother me as it looks cleeeean at last.

Why make it simple when you can make it complicated... Instead of destroying the plastic contactor, I put a drop of WD4O, for electrical contacts, two small wedges (mini nails) to force the contacts towards the welds. Adhesive, reassemble the screen, test, bingo!

v34 is pretty expensive, and I'm currently looking for alternatives. Does every polishing compound work that contains "medium" cut and some number between 2000 and 2500?

Do you have link to a full vídeo of disassembly process, please?

cool...robot voice

Perfect repair manual. Thank you!

Please more detail regarding what electrical connections must be disconnected and then re-connected

For all those with a screen where nothing seems to work try glass etching cream/paste. You can get this online and it's normally used to create etched designs on glass. It worked for me to get rid of all the coating from my 2015 macbook pro 15' after I tried everything including mouthwash, wipes, alcohol, acetone, baking soda - you name it, I tried it and ended up with a blotchy screen. The whole thing took 30 minutes and this is what I did: covered the body with a plastic bag taped down to create a proper seal; taped around the edge of the screen (even though these protective measures were overkill as the paste dries quickly and becomes non-reactive); cleaned the screen with alcohol; placed laptop on towel with screen down and body at 90 deg. angle; put on rubber gloves (important) and applied cream in sections with a rag and worked it in a circular motion for several minutes until cream was dry (don't apply and leave for longer than a couple of minutes); used another rag to remove the dried cream and polished the treated area; continued process until entire screen is done (worked cream into edges and used finger - as long as you're wearing rubber gloves - to apply cream in corners and around edges); used paper towels to polish the entire screen and old toothbrush to get dried cream out of hard to reach areas around the rubber seal; removed protective tape and bag; cleaned screen and edge with alcohol (isopropanol). The end result was a screen with no coating that looks like new. I normally don't share tips online but thought you might benefit from knowing that this approach really works.

Thank you for video.

Would this be basically the same process for the 2017 iMac 27 in? My iMac boots up, fan turns on and the startup chimes normally, but the screen is black and will not turn on. I took my iMac to my local U Break I Fix store and they said that the login name and round logo can be seen faintly. They couldn't pinpoint the exact problem, but they narrowed it down to a display replacement or replacing the backlight chip.

you NEED to blow out the heat sink fins too. My fins were so covered- you couldn't see through them. I actually removed my motherboard so I could really get at the fins on both the CPU & the GPU. I almost considered applying new thermal paste on both processors but when I saw all the dust buildup on the fins; I knew I found my overheating problem. My CPU average temps went from 195ºF to 130ºF, GPU at high load never goes higher than 185ºF but generally runs around 160ºF. And this is with fans speeds under 2000RPM Prior to cleaning; with the fans @3500+ RPM; CPU temp 185ºF - 205ºF; then sudden shutdown; GPU would get too 200ºF + as well. Very unstable. Happy ending after a thorough cleaning. stay safe everybody.

great video top marks from me. thanks

Magic eraser worked for me

Hi did You make video for dissembling display for replacing whole light stripes ?

Mouthwash did nothing for me

what causes backlights to die?

Out of one full day looking at videos, oh God i spent hours watching videos! Yours might seem like the solution.. i will try it out tomorrow and see if mid grade compound will do the job. Thanks for sharing.

I have the Same Problem! But the capacitors didn't exploded, all i just did is remove all the parts then clean them or brush them lightly then put them together, and try if it works! (remember this method is temporarily not pure fix!) i just want to share with you! BTW My Monitor is NEC AS192M
