HP Notebook PCs - Diagnosing a Liquid Crystal Display (LCD) for Damage
LCD display screens on notebook computers are made of two thin layers of glass with dark liquid crystal material in between. The glass is covered on the outside by a layer of plastic. Customers often feel that there cannot be a broken LCD display because they cannot feel the break. However, cracks in the glass usually cannot be felt because the plastic covering rarely breaks or fractures.
When the LCD display glass is broken any of the following may happen:
It is important to understand that lines on the LCD can also be caused by video driver issues or a problem with the media you are using. Video driver issues can normally be resolved by downloading and installing a new video driver. However, if the damage is due to a broken LCD, you should understand the following policies.
Accidental Damage Protection (ADP)
HP provides its customers the option to purchase an Accidental Damage Protection (ADP) plan. This plan must be purchased prior to any damage occurring. Customers may purchase the ADP plan through the retailer where they purchased the computer.
The ADP approach is simple: you break it; we fix it, quickly and conveniently for you. The service covers all parts and labor, but more importantly, it also covers a complete range of damage that warranty or service contracts don't, including unintentional spills, drops, falls, and collisions. Accidental Damage Protection even covers a damaged or broken LCD display.
Customer Induced Damage (CID)
Customer Induced Damage is not covered under standard warranty. It is included only in Accidental Damage Protection. Most damaged or broken LCDs will be considered as CID.
Occasionally there are exceptions. Therefore, you may wish to contact a service agent for additional information. Also, for customers who receive their unit from service with damage, the repair will be set up as an exception.
Examples of Customer Induced Damage (CID)
The following table shows examples of damaged panels and common descriptions for the damage.
All of these examples are of damaged panels that would not be covered by standard warranty.
What can I do now?
In most cases, this damage is considered customer induced and is not covered by any standard warranty. Therefore, it will be the owner's responsibility to cover the cost of repair unless they have previously purchased ADP. If the computer is out of warranty, a fee-based service may be initiated by contacting HP.
If you do not have an Accidental Damage Protection (ADP) policy and do not want to pay for the repair of a damaged LCD, you can connect an external monitor and use the notebook as-is. Or you could purchase a keyboard, mouse, and monitor, and use the notebook as if it were a desktop tower. LCD screen damage usually doesn't affect the operation of the notebook computer. You can also remove the hard drive and use it in an external enclosure on another computer.
Attempting a do-it-yourself repair
Attempting a do-it-yourself repair on notebook computers is not recommended for most customers. An improper action can cause irreparable damage to the computer. It is recommended that all repairs be done by an experienced and authorized service provider. If you choose to perform do-it-yourself repairs, do the following to identify and order the correct replacement parts.
We recommend that you only order parts from an authorized HP repair parts dealer. Parts ordered from third-party companies may not perform as expected and may cause additional operational problems.
