You posted to 'PC Desktops', but the manufacturer's web-site:

http://h10025.www1.hp.com/ewfrf/wc/product?product=4164692&lc=en&cc=us&dlc=en&lang=en&cc=us

has a picture of a notebook computer.

So, if you need to ask HOW to replace the LCD screen, my strong recommendation is to STOP and take your computer to a qualified technician, for proper and safe trouble-shooting and repair.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS].

Have you fitted the correct screen? Make sure the part numbers are identical otherwise the LCD screen is similar to the LED screen.
Check your model number.

We can't see LED light chip directly


Post the laptop manufacturer name, and model number.
The model number is on the Bottom of the laptop.

Post in a Comment.

Plus add additional info about what are you referring to?

Offhand, I would guess a reference to the LED backlighting on the laptop.
If this holds true, and you have no Backlight, the normal procedure is to replace the LCD screen.

With most laptops utilizing LED's as a Backlight, the LED backlighting is incorporated into the LCD screen assembly, and that's why when the LED backlighting goes bad, the LCD screen itself is replaced.

You may want to try and call Olympus Customer Service to see if this is a part that is able to be purchased as a replacement part. Their telephone number is 800-622-6372 option 2 and then option 3.
