Question about HP Compaq Presario CQ70-120US Laptop
Usually this is a result of the ribbon cable being loose or worse broken. You can have it looked at by a tech or you can disassemble the laptop yourself to ensure the ribbon cable is securely in place. If you're lucky the cable will be a press on adapter on both ends so you can attempt to replace just that as a troubleshooting step. The worst case is purchasing a new screen. Cheers, Ravi Shanghavi
