HP 6730b Screen Replacement – Complete Guide in English

Replacing a broken, cracked, flickering, or blank screen on your HP 6730b laptop is one of the most effective ways to restore normal visual performance. Whether your display is damaged from impact, wear, or panel failure, this guide explains what to check, which screen type is compatible, and how replacement works.

Signs You Need a HP 6730b Screen Replacement

You may need a screen replacement if your laptop shows any of the following:

• Cracked or physically damaged display

• Lines or horizontal/vertical stripes

• Flickering or unstable image

• Dim or uneven brightness

• No image but power is on

• Color distortion or dead pixels

These symptoms usually indicate the LCD panel or its internal components have failed and need replacing.

Compatible Replacement Screens for HP 6730b

The HP 6730b typically uses a 14.1-inch LCD panel with an XGA (1024 × 768) resolution. Replacement options include:

1. Standard Replacement LCD

• Resolution: 1024 × 768

• Same quality as original

• Affordable and reliable

2. LED Backlit Replacement

• Brighter screen

• Lower power consumption

• Better energy efficiency than CCFL

• Slightly more expensive, but preferred if compatible

Tools You Will Need

Before starting a screen replacement, prepare:

• Small Phillips screwdriver

• Plastic pry tool (non-metal)

• Tweezers

• Anti-static wrist strap (optional)

• Clean microfiber cloth

No soldering is needed — the screen is connected using screws and ribbon cables.

HP 6730b Screen Replacement – Step-by-Step

Important: Always power off the laptop, unplug it, and remove the battery before beginning any repair.

Step 1 — Power Off and Remove Battery

1. Shut down the laptop fully.

2. Unplug the power adapter.

3. Remove the battery to prevent electrical damage.

2 — Remove Bezel around the Screen

1. Use a plastic pry tool to gently release the screen bezel (the plastic frame around the display).

2. Work slowly to avoid cracking the plastic.

Step 3 — Unscrew the LCD Panel

1. Once the bezel is removed, you’ll see screws holding the screen to the metal mounting brackets.

2. Remove these screws from both sides.

4 — Disconnect Display Cable

1. Tilt the screen forward.

2. Carefully disconnect the ribbon cable at the back of the LCD panel.

3. Do not pull on the cable itself—pull from a reinforced section or use tweezers if needed.

Step 5 — Install New Screen

1. Align the new screen in the same position.

2. Connect the display ribbon cable securely.

3. Re-attach the mounting screws.

6 — Replace Bezel and Battery

1. Snap the bezel back into place gently.

2. Reinsert the laptop battery.

Step 7 — Power On and Test

Boot the laptop and verify that the new screen displays properly — check brightness, color, and viewing angles.

Compatibility Checks Before Buying a New Screen

✔ Confirm the screen size (usually 14.1 inches)
 Check the resolution (most HP 6730b screens are XGA 1024 × 768)
✔ Verify whether the screen is CCFL or LED backlit
✔ Check the connector type and position (commonly a 30-pin connector for this model)

If you replace a CCFL screen with an LED version, make sure your laptop supports LED backlighting, as power and inverter requirements differ.

Tips to Avoid Common Mistakes

 Forcing the bezel off
 Pulling on ribbon cables instead of connectors
 Using an incompatible screen panel
 Touching LCD surface with bare fingers
 Not checking backlight type

Avoiding these errors ensures a successful installation.

Cost Considerations

The cost of screen replacement depends on:

• Screen panel type (Standard vs LED backlit)

• Whether you install it yourself or hire a technician

• Shipping or part sourcing fees

LED backlit replacements are usually more expensive but more energy-efficient and brighter.

When to Consider Professional Repair

Choose professional help if:

• You are not familiar with laptop hardware

• You want warranty or guarantee on the repair

• You need verification of compatible parts

• You want a faster or more precise installation

Technicians can also test display cables and motherboard connections to ensure no other parts are damaged.

Final Notes

Replacing the screen on your HP 6730b can make your laptop clear, usable, and productive again. A correct screen replacement restores sharp visuals, eliminates flickering or distortion, and extends the useful life of your laptop.
