If the screen is physically damaged or cracked, or if the hinges are broken, we do not cover the repair or provide a refund within a waranty. If the laptop does not turn on, or it turns on but there is no display, this could be related to a motherboard issue, and we do not provide a warranty for such incidents. The LCD must be intact with no signs of dents or drops. If it flickers or has lines on the screen, then yes, we offer a warranty within 30 days on our screen repair services.
