Cheapest LCD screen separator/heater

Can I use a small cheap LCD separator/heater for iPhone to replace LCD matrix on my 13’’ MacBook Air?

Update (08/30/2019)

Looks like heat is not necessary at all to remove the bezel. It could be done with a cheap razor blade. But be careful with the camera cable in the left-bottom corner. The display did not get a single scratch after the removal of the bezel.

Keep going… Maybe the display matrix could be removed similarly.

Update (09/01/2019)

I found out that adhesive tape on the right side of the matrix could be easily removed by simply pulling it out from the bottom to the top. The bottom side is detached by removing 5 screws on it. After that I inserted razor blade into the top end of the right side. 2 millimetres of the blade were between the matrix and the adhesive tape. The blade is flexible enough to dive into the narrow (1-2 mm) gap between the matrix and the aluminium case and then to make a 90 degrees turn to enter between the matrix and the adhesive on the aluminium body.

On making a turn at the top right corner, razor damaged the matrix. A very small piece of glass (0.5 mm x 0,5 mm) was detached from it and stayed attached to the aluminum body because of adhesive. Each matrix corner is made of a very thin glass. So the top left corner was damaged similarly when the razor blade made a turn.

The entire matrix was successfully detached without a single scratch on backlight sheets. But the matrix cannot be reused because of damaged corners.

After that I used cotton buds and acetone to remove remains of adhesive tape from the aluminium body.The outer parts first. Acetone from nail polish removal bottle acts like a hot air gun: adhesive become very soft and easy to remove. When I removed adhesive from the inner parts which are very close to the backlight sheets, I tried to remove excessive acetone from cotton bud. But one time I just forget to do so. Acetone leaked and penetrated free space between the 2 topmost backlight sheets. Now I have an ugly blot on the 2 topmost backlight sheets.

One could think that the need of buying an incomplete set of 4 backlight sheets makes the entire replacement too expensive. But In fact the price of an incomplete set of 4 backlight sheets from an old MacBook is identical to the price of the cheapest hot air gun which I did not buy. I also did not buy any other special equipment for detaching bezel or LCD matrix. So the overall price remains low.

Take the time to review the two links I have in my answer on the next steps.

@danj I watched them all but I still cannot find out how to attach the backlight Sheet N2 which is connected to the electricity. Looks like it is attached by special adhesive which conducts electricity.

It was detached very easily. But how to attach it back without any subsequent problem - that is not clear to me.

Why did you take it out? It looks like your display was OK as well??

par

@danj I've made a bad mistake during cleaning. I used acetone for it. It leaked and damaged display sheets. I decided to replace them all with the new ones.

Sadly, you've dived deeper than I have. I've only replaced the LCD.

Misha Krasnorutsky  for as long as you get to heat it uniformly you should be okay with it. There is no reason why it should not work. Give it a try and let us know how it worked out.

I will try it next month. There are still some things that I can't figure out. One of them is how to attach the matrix straight. As far as I know, I should first attach the metal bottom part to the matrix. I suppose there will be some special marks on the bottom edge. These marks will help me to attach the metal part to the right place.

The second thing is how to put the backlight components to the right position.

I suppose I can use a hot pan with recently prepared borscht instead of LCD heater. Because the water temperature cannot be higher than 100. And after a few minutes it will be about 80 celsium degrees. And then I simply put the pan on the LCD back side.

par

Misha Krasnorutsky not sure about the Borscht since I do prefer Perogies. Yes, you could use a pan if you have constant heat and can control it :-)Add some pictures of your setup etc. so that we can see what you see and that way we can all create a plan together.

Unlike an iPhone or iPad you really can’t separate the cover glass from the LCD panel as the glass is part of the LCD its self. Review this Youtube vid MacBook Air 11-inch LCD Screen Take Apart note how thin the full panel is!

I don't want to use vacuum to separate the screen. I want to use this cheap device only as a heater with temperature control. Such devices are usually smaller (7 inches) than MacBook Air LCD screens (11-13 inches) - but I hope I can still use them.

I suppose if I heat up the aluminium back part, nothing bad will happen to the other parts.

Sometimes you need to heed someones vast years of experience. I've been fixing systems for over 40 years.

While you may not have the correct tools force fitting a tool to do a job it's not able to do will more than likely fail. I think you'll have to give your way a try but don't expect it to succeed.

@danj This guy on the video

https://www.youtube.com/watch?v=2YscW-yl...

uses a heater plate at 80 celcium degrees.

He said (in Russian) that using heater plate is much easier because everything can be separated very easy.

Let's look at this from a physics point of view I have a metal rod which has mass. If I heat one end of the rod it will take a bit of time and a lot of heat for the heat to reach the other end of the rod and the entire rod would end up being heated. Let's say the glass attached to the other end of that rod and then the bezel. Wouldn't it be just easier and require less heat to just heat the bezel than all of the pieces in-between? Here only heating a small area and carefully lifting the bezel plate.

Don't forget you will damage the sheets that sit in the well of the lid. So you can't heat the lid that high to get the heat through the metal, glass and bezel. The person is struggling in your vid not in mine.
