Introduction

When trying to troubleshoot the monitor, check for the most obvious physical problems. Such as, a crack on the outer case of the monitor, shattered LED screen, or low light emission from the LED.

Parts

No parts required.

If there is a crack on the outer case of the display so that the display is working properly, but there is distractions on the screen from the shattered case. In that case, the outer case can be easily replaced. It is just a matter of pulling the plastic case that’s stuck against the LED screen, and push the new case back in its place.

•    Shattered LED screen is when you push your finger against the screen, you see some kind of a rainbow effect around your finger. If the LED screen is shattered, it is unusable, and needs to be replaced with a new LED screen.

If the light coming out of the display is not bright enough, check the picture settings manually, and try to adjust sharpness, contrast, and brightness.

•    If setting the picture manually did not change the brightness, it simply means that the LED in the back of the LED screenis broke. That means a new LED screen is required.

In order to get to the screen assembly, you need to remove the screen bezel (plastic frame around the screen)

To remove the bezel, you need to unscrew two screws in the bottom of the front screen hiding behind screw covers.

Frist, remove the screw covers with a small hobby knife. Use a PH #0 (Philips screwdriver) to unscrew the couple of screws in the front screen bezel.

Once you are done with unscrewing, snap off the screen bezel. To do that, you need to reach your fingernails of both hands on the inside of the screen bezel in the left or right side of the screen, and gently lift up and out.

This assumes the reader has fingernails! You should be using the appropriate pry tool for this step.

You will hear a snapping sound. Work your way around the screen bezel.

Once you take out the screen bezel, four screws mount the LED screen. Unscrew them, tilt the screen forward, and lay it on the keyboard exposing the backside of the screen.

Feels like there should be a "before" picture of the screws that need to be removed here.

Also, my Toshiba Chromebook 2 (CB35 - B3340) had no screws. Just adhesive in the four corners of the LED. Rest of the repair works.

Once you do that, you will see the screen has only one connector. Use the hobby knife to lift up the adhesive tape (Be careful not to cut it) Pull the adhesive tape back, and grab the back of the connector with both your fingers, and gently pull the connector back out. Now the screen is loose.

You have a caution noted in parenthesis that should have a special bullet.

Put the new 13.3’ LED screen in its place and start by connecting the screen connector. Put the screen where it is supposed to be mounted at, and screw back the four screws that hold the screen.

Now it’s a matter of putting the screen bezel back by pushing it in to stay around the screen.
