The phone repair business is booming due to all the cracked screens, why are you not taking the opportunity to make some easy money? Any one can replace a cracked screen with a brand new screen assembly, but this is not what this tutorial is all about. If you are looking to just replace your screen with a screen assembly, check out my other instructable called "How to Repair Your Cracked iPhone 5 in Less Then 20 Steps". What this instructable is all about is making a bigger profit margin from repairs. I have been in the business of buying cracked iphones and ipods on ebay for dirt cheap and replacing the screen with a screen assembly. I easy made over $2,000 a month doing this. I dedicated a lot of time, but I became an expert over time and did each repair and sold it back on ebay the very same day I received them. I would make sure I would have a constant stream of iphones getting shipped to me by constantly monitoring auctions. All I did was search up "cracked iphone". You will be amazed how many there are and how cheap. This was my income while I attended college. Let me tell you, it does NOT take a genius to fix these things!
As time went on, I began to ponder why I could not salvage the lcd. While the glass screen was clearly cracked and needed to be replaced, the lcd was just fine. Just seemed like a waste of resources to be buying a prebuilt assembly when all I need was the glass! However there was no way to get that pesky glass of the lcd display, believe I have tried! Upon further research I found a lot of people selling glass only replacements on ebay. Were these people trying to scam me, or did they know something I did not?
So I took the task to google and did some research. What I found did not surprise me. Hundreds of posts all over the web asking how to separate the lcd from the glass. Yet all the answers yelled back "Impossible!", "cannot be done!", and "Don't waste your time". Surely somebody out there has to have figured out how to separate the cracked screen.
That very day I discovered it. It is a tool called an lcd separator machine. I am not going to describe too much into detail what it does since I want to show you how to use it, but if you want to learn more about the device check out some lcd separator machine reviews and you will understand.
In this instructable, I will guide you how to separate the lcd from the glass on an iphone 5s, and then put on a brand new screen. Again check out my other instructable if you need to know how to take the iphone apart.
What you will need:
- lcd separator machine
- Goof Off spray
- iPhone 5s mold
- loca glue
- replacement glass
- uv light
Make sure you are working in a dust free area!
Step 1: Set the Temperature
Turn on your lcd separator machine and put the temperature to 80 degrees. Let the machine heat up. It will tell you when it has reached your desired temperature.
Step 2: Put the Screen Onto the Hot Plate
Once the alloy plate is hot enough, put the broken assembly on to it. Clamp it down with your four clamps that are attached to the machine. Make sure the assembly does not move around.
Step 3: Use the Molybdenum Wire
Slide the molybdenum wire into one side of the assembly. Get it in between the lcd and the broken screen. Gently move the wire back and forth like you would be flossing your teeth. Once you reach the end, go back to the other side. Keep repeating until the lcd is loose and you can take it off.
Step 4: Use That Goof OFF!
You can now turn of the lcd separator machine and toss the broken glass into the trash. The lcd will have the loca adhesive glue on it. You need to take that off so it is nice and clean. I prefer to use Goof Off as it seems to work the best, but you can try any adhesive remover you would like. After the adhesive is removed, wipe the lcd with some rubbing alcohol. Make sure there are no smudges or finger prints on it.
Step 5: Put the Lcd Onto Mold
Once it looks nice and shiny like new, put it into your mold. The mold is meant for the replacement glass to align perfectly. You can try without it, but these molds are pretty cheap.
Step 6: Loca Glue Time
You probably noticed this by now, Apple or any other phone company does not use any regular glue. They use loca glue, which stands for liquid optically clear adhesive. If you want to learn more about it go ahead. All I am going to say is that you cannot use any other glue besides this adhesive. It is meant for touch panels.
Apply the loca glue like the pattern shown in the picture. This pattern is so there are no bubbles.
Step 7: The New Glass Screen
Once you put down the loca glue, it is time for the new screen. Do not rush this step, don't worry the glue does not dry. Put one end of the glass at the end of the lcd and then slowly lower the other end. Once the loca glue gets a hold of the glass it will spread out by itself. No need to put heavy pressure onto the screen as the glue will move to fill out slowly.
Step 8: UV Light
Now the cool part. Loca glue does not dry by itself. The only way it cures is by uv light. You will need to buy a uv lamp. I just took my girlfriend's uv nail dryer, works the same and more convenient :). All it takes is 5 minutes and the glue is dry. Wipe off any excess glue off the sides. Your screen is now ready to be put onto the iphone!
Step 9: Conclusion
This repair does cost an initial investment for the tools, but you will get your money back after 3 repairs. A screen assembly costs over $25, a replacement glass costs $6. If you were to replace the assembly and resell it back on ebay you would make over $60 since iphone 5s are highly priced right now since they are the latest version. So think about it, if you begin to salvage the lcd that is an estimated $19 profit added onto the repair job.
Why give away my money making technique? I recently graduated college and have obtained a full time job that pays me more then I could ever make from the repair business. Making money to pay the bills is a challenging aspect to everyday life, trust me I went through it just like you. I do not do this anymore so I do not care if more people know about it, I rather help someone out then keep it a secret. I just wanted to make this instructable to help answer so many questions that I receive on a daily biases. I hope this helps!
