Introduction

This laptop needed a new LCD. It is actually a straight forward task and does not require a lot of special tools. I did remove the fan since it was easier to remove one of the connectors, but it is not an absolute must, I just preferred it that way.

Okay, so here is a HP 6730b that was accidentally dropped. The cracks in the LCD are clearly visible on the left side of the image. Shut down the computer. Disconnect all external devices connected to the computer. Disconnect the power from the computer by first unplugging the power cord from the AC outlet and then unplugging the AC adapter from the computer. Close the screen and turn the computer over. Remove the memory/WLAN module compartment cover by loosening the Phillips 2.0×5.0 "captive" screw. They are secured by a spring clip at the back, so they will not be easily removed. All that is required is to loosen those.

The last steps are to remove the display hinges from the LCD panel. Remove the four Phillips screws from each side of the panels. The panel is now ready to be replaced. With everything re-assembled, hopefully this is something like what you will see.

A great guide - clear instructions. However, there was a missing step at the end, step 15, which was to move the ribbon cable from the back of the old screen on to the new screen. My new replacement screen didn't have this cable, but moving it is easy enough to do. Thanks!

I would like to express my thanks to the author of this guide - the instructions are extremely comprehensive and the pictures are very helpful. As with the earlier contributor, I had to move across the cable from my old screen to the new one, but much more importantly thanks to the guidance set out above I once more have a laptop I can use. Thanks again!
