I purchased a used laptop computer, DELL Latitude 3510, on Yahoo! Auctions, but I noticed that there were burn marks (pressure marks?) on the LCD screen, as shown in the gallery below.
If I had noticed it sooner, I would have returned it, but since quite a few days have passed, I gave up on returning it and decided to replace the LCD panel myself. At the same time, he will increase the memory from 8GB to 16GB.

The specifications of this machine are as follows.

Pre-prepared tools and parts

The tools and parts prepared in advance for the work are shown in the gallery below. In this example, we prepared a 10 mm wide (transparent) double-sided tape for the tool, but since the display bezel has very narrow widths, we recommend using 3 mm wide double-sided tape (black) for repairing LED screens. recommend to.
Actually, if I used transparent double-sided tape, the gap between the bezels would look whitish and the border with the LCD wouldn't fit properly, so I replaced the bezel with black double-sided tape later!
Actually, I replaced it three times and finally got the hang of it 🤦‍♀️

Removing the display bezel

This model has a thin display bezel with almost no gaps, so use a stainless steel peeler. Once the spatula gets into the gap, switch to the Jirako spatula and carefully peel off the bezel.
When reusing the display, be careful not to damage the LCD panel with the spatula.

Removing the LCD panel

Pull out the double-sided tape protruding from the bottom of the left and right sides of the LCD panel. Perform this on both the left and right sides. When you remove this double-sided tape, the LCD panel will come off at the same time.

LCD panel cable removal

Disconnect the cable connector circled in red. The connector is covered with an insulating cover and locked, so peel off the insulating cover, then use tweezers to release the lock and pull out the connector.

Preparing a replacement LCD panel

I prepared the following LCD panel purchased from Yahoo! Auctions. Please note that this LCD panel does not have screw holes for mounting. The LCD panel of the Latitude 15 3510 (P101F) is compatible with both types with and without screw holes.

Installing the replacement LCD panel

After connecting the LCD panel cable connector to the replacement LCD panel connector, apply new insulating tape (black) over the transparent insulating tape to secure it in place.
The cable for the LCD panel should be hooked to the metal claw at the left end of the cable facility groove (red line) at the bottom, and then laid along the groove. If a claw sticks out toward you when disassembling it, use a flathead screwdriver to press it down firmly to crush the protrusion. If there is a protrusion, the left side of the bottom edge of the bezel will not stick properly.
Also, the two parts on the back of the bezel hinge are joined with nails, so turn the main body over and press it with your hands to secure it firmly.

Operation test

Before assembling, check the operation by supplying power from the AC adapter. Currently, 8MB of memory has been added to 8MB, so it is OK if the installed RAM can be recognized as 16GB.
After testing, remove the display's protective sheet and attach the display bezel.

Installing the display bezel

The double-sided tape on the display bezel is useless once removed, so remove all double-sided tape that is stuck halfway. After removing it, apply new double-sided tape (black double-sided tape with a width of 3 mm) along the inside of the bezel frame.
Peel off the protective sheet on the replacement LCD panel and attach the display bezel.

When you install the display bezel in the process of "Applying new double-sided tape (1-2)" below, the adhesive tape at the bottom edge of the bezel will stick to the masking cellophane (black) of the LED backlight of the display, so you will have to peel off the bezel. To be on the safe side, you may want to extend the tip of the double-sided tape to the outside of the display bezel without removing it, so that you can remove the tape from the outside after final confirmation.

In this example, transparent double-sided tape is used, but as mentioned above, we recommend double-sided tape (black) for LED screen repair with a width of 3 mm.
If pasting fails and you need to re-stick the bezel, completely peel off the peeled-off LED backlight masking cellophane at the bottom of the LED, then apply two rows (6 mm) of double-sided tape (black) for LED screen repair with a width of 3 mm. Width) and reupholster.
The trick to attaching the bezel is to slowly and carefully attach the bezel while making sure that the width of the black edge of the screen at the four corners is even. Therefore, the screen should be in a display state when pasting.

Installing the battery and base cover

After installing the display bezel, connect the battery cable connector inside the main unit, and then install the base cover.
For the final test, press the power button to power on the battery and confirm that the battery status is normal.
