Testing your iPhone LCD screens without the proper device is too time consuming and often times gets neglected when repair store owners purchase wholesale LCD screens for their shops. Every iPhone repair shop should have one of these iPhone tester machines in their store.
This device doesn’t have a brand name and comes straight out of China. There is an English and Chinese version. The first one I bought was actually Chinese but only took a little tinkering without instructions to get going. It’s not a very complicated device.
iPhone LCD Tester Compatible List:
This specific iPhone testing device will test iPhone 4 and iPhone 4s LCD screens. It doesn’t matter if it’s CDMA or GSM. It will not test iPhone 5 LCD screens.
The iPhone LCD Tester Kit Comes with the Following Items:
- Main Testing Box
- Replaceable Flex Connector Circuit Board
- AC Wall Adapter
I’ll highlight a few reasons why you should pick one of these up ASAP.
- Initial Quality Control – In every batch of wholesale LCD screens that you purchase, there are bound to be some defects missed by the manufacturer, distributor and in the shipping process. Even if it’s under 5%, you’re able to quickly get together an RMA to your vendor days or weeks faster. With the volatility of some of the higher end screens, it’s important to sift through any defects quickly and return them before the value is lowered.
- Hooking up LCD to iPhone LCD Tester Device – Connecting the LCD and digitizer flex is much easier than on a mainboard because there are no other parts that get in the way.
- No Mainboard Needed – You do not need an iPhone 4 or 4s mainboard to test. The connections on the mainboard are not designed to be connected and reconnected hundreds of times. They will eventually go bad and, unless you know how to solder or re-flow, you’ll end up with a worthless paperweight. With this device, when the connection contacts wear out, you replace just that one part for about $15-$20.
- Quality of Test – Once you’ve connected and started the process, the first thing that appears on the screen is a high resolution image. Spotting fake iPhone screens is pretty easy. Then a button is pushed and it runs through ROY G BIV colors so you’re able to spot any dead pixels, discoloration, screen burns or watermark spots. If the digitizer has some bad spots, it can and will tell you. The digitizer test is not perfect, but it does a fairly good job. Also, if it detects any grey lines or dead spot areas, the test will stop and prompt the user to continue through the test.
- Speed of Test – Our technician, Kirk, is truly a one man machine. Using two devices at the same time, he’s able to test about 1,500 LCDs a day. If challenged, he could do many more. There is no wait time for the device to boot up in between screen tests and the programming automates a lot of the process. It’s made for speed. The average time for an everyday tester I would estimate to be at no more than 15-20 seconds per screen – including hookup, test and disconnection.
- Use of Flex Extenders – Many repair stores use a flex extender with an iPhone board to conduct their test. It reduces the number of connections to the mainboard and gives you more flexibility when connecting and testing the LCD screen. With this device, you can use the same flex extenders to prolong the use of the replaceable chip. These run for about $5 to $8 each.
