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?
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.
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.
