troubleshooting tips for a non responsive screen

Low quality replacement screen

Not all smartphone screen replacements are created equal. Lower quality replacement parts could be refurbished or unreliable. If a deal sounds too good to be true, it probably is. Make sure you buy your smartphone replacement parts from a trusted source, like

Connectors not reseated properly

When you reassemble your device, it’s easy for connectors to get reattached to the wrong spot, turned around, or mixed up in the process. If you are having trouble with your screen, double check that all of the connectors are facing the right way and are making good contact with the motherboard.

Replacing only the glass

The LCD and Digitizer are sold together for a reason – it’s extremely difficult to separate them without causing serious damage. So that “bargain” screen replacement might just be glass, and it might end up costing you extra in the long run.

Damage from static electricity

The tiny electrical components of a smartphone or tablet are extremely delicate. Fuses can be blown by something as minor as static electricity, so you might want to wear an anti static wrist band before you handle the interior parts of your device.

Screws missing or out of place

When putting your device back together, it’s crucial to put every screw back in its proper place. Keep track of where screws go by grouping them in empty ice cube trays or sticking them to the back of a piece of tape. You can also use a magnetic screwdriver to help keep track of small metal parts. Also take care not to tighten screws too tightly.

Debris on internal components

Oil from your fingers, dust, and moisture can all cause damage to the internal components of your device. You can avoid this by wearing gloves and working in a clean environment.

Software not recognizing new hardware

Sometimes your device fails to recognize the replacement screen you installed. This issue can often be resolved by disconnecting the battery for a few moments, then reassembling the phone as usual.

Camera shorted out

If your screen is completely blue, it might be due to a problem with the front facing camera. Try disconnecting the front facing camera and turning the phone on. If the screen works after this, you need to replace the front facing camera.

Cables or pins bent out of place

There are lots of tiny parts within your phone, if any of them have been bent too far or moved out of place, your device will not work. If any of these components are damaged, they must be replaced.
