Einleitung

Here is a Toshiba C655D-S5200 that had a broken case. It had severe water damage and the case was broken at the hinges. I salvaged as many parts as possible and wanted to use the LCD panel for a project. Over the last few years that I have been a member of iFixit, we had a couple of questions about what to do with spare panels. So, I figured I'd spend $32 and purchase a LCD controller board and investigate how difficult it would be. The trickiest part was to find a controller board that matches the panel.The LCD panel in this Toshiba is a LTN156AT05-U09. I contacted a couple of vendors on Ebay and found one that was very responsive and accommodating. I ordered the controller board and it arrived in 2 weeks from China.

    • Here is the Toshiba with the water damage and a broken case.

    • The LCD is in good shape and has no cracks.

    • Visible damage to the hinges that lifted the entire top case

    • Four rubber plugs covering some screws.

    • Removing the plugs reveals the Phillips screws.

    • as well as the right bottom

    • Use a plastic opening tool, or similar to pop the bezel of the LCD assembly

    • Continue to slide the tool all the way across the top

    • Once the bezel has been released from the tabs, it can be further released be applying some gentle manual pulling

    • Continue to pull on the sides

    • and finally on the bottom.

    • With all the tabs released the bezel can now be removed

    • Here is the LCD assembly without the bezel

    • Remove the Phillips screw that connects the LCD frame to the back cover. This is the left one

    • The LCd can now be moved forward and away from the rear cover

    • There are three screws on either side that hold the panel to the frame. Remove those

    • Here are the three M2x4 screws

    • Remove the three Phillips screws on the right side as well.

    • with the screws removed the panel can now be moved out of the LCd frame. The LCD is still connected by the display cable.

    • Here is the panel number clearly visible. this is an important number and needs to be noted.

    • Remove the display cable carefully. It is very thin and this particular one had some clear tape holding the cable to the panel. Remove it if it is present and disconnect the cable

    • LCD panel all separated from the laptop.

    • Here is the universal driver board. It also includes a separate PCB for the menu button. The cable is 40cm long and will allow for multiple choices for a custom case

    • Here is the only shortcoming of this kit as far as I can see it. The menu buttons are on the same side as the cable connector, it will get in the way of placing it in a case. Some re-soldering may be necessary

    • All it takes to connect the driver kit to the LCD panel is to plug it in. The connector is a perfect fit.

    • This kit offers HDMI, DVI and VGA input. I opted for the VGA for testing purpose

    • The LCD driver requires 12Volt to work, I used a spare 12V 1.4A switching power supply. the LCD fired right up and displayed a crisp image.

    • Only shortcoming on this kit, the push buttons for the menus are in the same direction as the cable connector. Otherwise this kit definitely exceeded my expectation.

    so i bought a lcd controller board turns on fine the only problem is that is shows 4 squares with the same images

Now its time to think about a case for the monitor. Great little project for a rainy day and it does save another LCD panel from the landfill.

Hello, Nice work…i have v56 universal board with LP154WX4 (TL) (C1) ..after the firmware is installed …i just get very light blue color display…not able to figure out the problem ? can you please suggest….?

Silas Paine -

Another issue, if it’s like mine, is that the color accuracy (and bit depth?) isn’t too good. I used an LCD out of a top-end 2008 Macbook Pro, so I know the color should be better than it is.

James Nielson -

does the board support 14’’ lcd screens?

VALEN FRANCIA -

that will depend on which board you have and if it is listed as supporting your monitor. The trick here is to match the monitor with a driver board. Always verify this with he vendor.

oldturkey03 -

Same here. In my case I have a pile of LCDs but the problem is most of them are the older type are CCFL backlit.

Unfortunately there aren’t that many applications for a CCFL VGA 14.1” panel but anyone who does come up with one please message me “darnstadium

@oldturkey03 - Noting the shortcoming you mentioned, I have an idea for you. It looks to me like the connector is simply a straight line of pins, in a through-hole configuration. I'm thinking you could desolder the connector from the board, flip it 180 degrees and resolder it on the other side. In a single line connector the pins will still be in the same position, only now mounted on the back side, which is what you were hoping for in the first place. Hope that works for you!

@dadibrokeit yes it was actually fairly simple to adjust it for my needs. Luckily the maker of that kit had subsequently made revision to the button bar as well :-)
