As an expert in display technology, I can provide you with a comprehensive guide on how to determine if your LCD screen is broken. There are several signs and tests you can perform to ascertain the condition of your LCD screen.
Step 1: Visual Inspection
The first step in diagnosing a broken LCD screen is a thorough visual inspection. Look for any visible cracks, discoloration, or dead pixels on the screen. Dead pixels are small dots on the screen that do not change color and could be black, white, or any other color. A cracked screen might indicate that the glass is broken, but the LCD underneath could still be functional.
Step 2: Power On the Device
Turn on the device and check if the screen lights up. If the screen remains black or shows a distorted image, it could be a sign that the LCD is damaged. However, if the screen lights up but has lines running across it, it might be a loose connection rather than a broken LCD.
Step 3: Test the Touch Functionality
If your device has a touch screen, test its functionality. If the screen is cracked but the touch still works, it might be that only the glass is broken. However, if the touch does not respond, it could indicate that the LCD, which is responsible for touch functionality in many devices, is damaged.
Step 4: Check for External Damage
Examine the device for any signs of external damage that could affect the screen. This includes dents, deep scratches, or any other physical trauma that could have caused internal damage to the LCD.
Step 5: Connect to an External Monitor
If possible, connect your device to an external monitor or TV. If the image displays correctly on the external screen, it could mean that the LCD in your device is broken, as the image data is being processed correctly but not being displayed on the device's screen.
**Step 6: Test with a Different Power Source**
Sometimes, a device might not display an image due to a faulty power source or battery. Try charging your device fully and then test the screen again. If the problem persists, it's less likely to be a power issue.
Step 7: Software and Firmware Checks
Ensure that your device's software and firmware are up to date. Sometimes, display issues can be caused by software glitches that can be resolved with an update.
Step 8: Professional Diagnosis
If you're still unsure, it's best to take your device to a professional for a diagnosis. They have specialized tools and expertise to accurately determine if the LCD is broken.
Remember, replacing an LCD screen can be a complex process and is often best left to professionals. If your LCD is indeed broken, it's important to have it replaced as soon as possible to prevent further damage or data loss.

If your screen looks fine and all touch works but is cracked then you just need the glass, but if the screen looks black or touch will not work then you need a LCD. Another way to find out if the LCD is broken is to bull down the scroll bar and move it back and forth on every side to see if the touch works.Aug 21, 2014
