In most cases, laptop screens are replaceable and won't justify buying a new device. So, if the replacement price exceeds the cost of buying a laptop, it might be time to invest in a new one. If the display is functioning correctly, it is likely that the connection has become loose or the screen itself is damaged. Consulting a screen repair specialist will help you identify what is needed to fix this issue.
At times, the broken or cracked screen may have damaged the main components of the screen and rendered it unusable. When this happens, the repair can be too expensive, as the LCD panel and sometimes even the entire laptop case needs to be replaced, in addition to the screen and hinges. Windows laptops come in various sizes, so it would be difficult to list all the costs of laptop screen size. If you don't have time to take your computer to a store for repair right now, consider connecting an external monitor to your laptop or MacBook via the HDMI or Thunderbolt port.
If the laptop model is old and its parts are hard to find, opting for a new laptop is the best option. If the laptop model is recent, then it doesn't make sense to buy a new one just because of a broken screen. Having a broken laptop screen is inconvenient, but you can still use your computer and access your data even if the display is damaged. A computer repair specialist will be able to properly assess your laptop's broken screen and let you know if it's worth repairing.
But if for some reason your laptop screen breaks, try visiting a certified repairer to replace it. A screen uses many technological components, which sometimes means that older computer models are too outdated for screen replacement to be effective.
