Common faults and repairs of LCD monitors

Black screen or no display:

Possible causes: This may be caused by power problems, wiring problems, backlight failure, or a fault in the monitor itself.

Solution: First check whether the power cord is connected properly to ensure a stable power supply. If the power is normal, then the problem may be in the wiring, and you can try to replug the connection cable. If none of the above methods work, you may need to contact a professional repairman for processing.

Color distortion or offset:

Possible causes: This may be caused by signal transmission problems, driver errors, or problems with the monitor itself.

Solution: First check whether the cable connection is firm and ensure that the signal transmission is normal. If the problem persists, you can try to update or reinstall the monitor driver. If the problem still cannot be solved, you may need to consider replacing the monitor.

Uneven brightness:

Possible causes: This may be caused by aging of the backlight, damage to the backlight tube, or other hardware problems.

Solution: Check whether the backlight is evenly illuminated. If you find that the brightness is darker or brighter in some areas, you may need to replace the backlight tube. If the problem persists, it is recommended to contact a professional repairman for diagnosis and repair.

Dead or broken pixels:

Possible causes: This is usually caused by a pixel failure or physical damage to the screen.

Solution: For pixel failures, you can try to use some pixel repair software to fix the dead image. But please note that this does not guarantee a complete fix for all problems. If the problem is severe enough to affect use, the entire monitor may need to be replaced.

A Practical Guide to Customizing TFT LCD Displays for Embedded Projects

When designing an embedded system, picking the right display module is more than a technical choice — it directly shapes how users interact with your product.

From medical devices and HMIs to industrial controllers and smart panels, standard TFT LCD modules may not always be enough. That’s where custom displays come in — offering flexibility in electrical interface, mechanical layout, and visual performance.

This guide covers the five key areas you should consider when customizing a TFT LCD for your embedded project.

1. FPC Layout and Pin Mapping

The Flexible Printed Circuit (FPC) connects your LCD module to the mainboard, and in custom designs, this interface is often the first thing to change.

Ask yourself:

Do you need a uniquely shaped or angled FPC to fit inside your housing?

Are there ICs, resistors, or other components on the backlight or CTP that require mechanical clearance?

Is your SBC’s connector pinout compatible with the LCD’s FPC layout?

A mismatch here can lead to signal errors, mechanical stress, or even damage to components.

2. Backlight Brightness and Color Temperature

Not all embedded devices live under the same lighting.

If your product is used outdoors or in industrial lighting, consider high-brightness backlights (≥800 nits). For environments where aesthetics and color warmth matter (like smart mirrors or indoor kiosks), choose the right LED color temperature:

3000K (Warm White): Soft, suitable for medical or ambient lighting

5000K (Neutral White): Balanced tone, accurate colors

6500K+ (Cool White): Sharper, more industrial feel

A poorly lit display can make a great device feel underwhelming.

3. Touch Panel Shape and Bonding Options

If your display includes a touch interface, customizing the Capacitive Touch Panel (CTP) is critical.

Typical customizations include:

Round corners, logo cutouts, button holes

Bonding methods:

Optical bonding: Improves visibility, reduces reflections, stronger seal

Air bonding: More affordable and easier to assemble

The bonding method directly impacts touch accuracy, display clarity, and long-term reliability.

4. Surface Treatments: AG, AR, and AF

For devices exposed to bright light or frequent finger contact, display surface treatments make a noticeable difference.

AG (Anti-Glare): Scatters reflected light, improving readability

AR (Anti-Reflection): Enhances contrast in sunlight or strong lighting

AF (Anti-Fingerprint): Reduces smudges, improves touch feel

Combining AG+AF is a common choice for public-facing touchscreen displays.

Recently found out that the Rand McNally TND 550 has no references anywhere online for how to open it for e.g. a battery replacement.

Let me throw my two cents in!

I found out the hard way that using a heat gun to pry off the touch panel only grants access to the, uh, touch panel adhesive backing. That is not the way to go about this.

Turns out the body clips together - the seam between the rubberized back portion and the glossy plastic front portion is where you gotta attack it with a metal spudger blade. Bottom center is the best starting point because it's relatively flexible and also the least seen place for if/when you scuff the plastics. Then it's just a matter of moving around the seam, unclipping the two pieces. Once it's fully open, make sure to watch for the two ribbon cables - one goes to the LCD and the other to the TFT panel.

Basically, like opening a 4th gen ipod, but the seam is a lot tighter.

I hope this helps at least one person avoid my heat gun mistake haha

What are the common sizes and resolutions of industrial control displays? How to choose?

The size and resolution of industrial control displays need to be selected in combination with the application scenario, operating distance and display requirements. The size and resolution of industrial control displays are very diverse and need to be determined according to specific application requirements.

Common sizes and resolutions of industrial control displays:

Industrial control displays have a wide range of sizes, from small 6.5 inches to large 55 inches or even larger, and resolutions range from lower 640x480 (VGA) to ultra-high-definition 3840x2160 (4K UHD).

Common sizes include 6.5", 7", 8", 10.1", 10.4", 12.1", 15", 15.6", 17", 19", 21.5", 22", 23.6", 24", 27", 32", etc.

Common resolutions include 640x480 (VGA), 800x600 (SVGA), 1024x768 (XGA), 1280x1024 (SXGA), 1280x800 (WXGA), 1366x768 (HD), 1920x1080 (Full HD), 1920x1200 (WUXGA), 2560x1440 (QHD) and 3840x2160 (4K UHD).

Selection of industrial display screen size and resolution:

Choosing the right size and resolution requires comprehensive consideration of key factors such as application scenarios, display content, viewing distance, installation space, budget, operating system/software support, etc. Applications with large amounts of display information and long viewing distances require higher resolutions and larger sizes.

The operating system and software also need to be able to support the selected resolution. When touch function is required, the size should be moderate and easy to operate. Budget is also an important consideration. When choosing, it is recommended to give priority to application requirements, and then choose the most cost-effective product within the budget.

In short, choosing the size and resolution of the industrial control display is a trade-off process, which requires comprehensive consideration of factors such as application scenarios, installation space, budget, operating system and software support. It is best to consult a professional industrial control display supplier, provide your specific needs, and let them recommend the most suitable model for you.

DIY: Marauder with Screen and GPS For Flipper Zero

Many of you would have seen the humongous ESP32 add-on module with touch screen and GPS for Flipper Zero shared in discussion groups, forums, etc. Well, this tutorial will provide you with all the information you need to build one yourself.

This build consists of mainly 4 parts. The TFT LCD 2.8" 240x320 SPI ILI9341 Touch Display cost me around US$5.50, the ESP32-WROOM-32U module cost around US$3, the NEO-6M GPS module cost around US$2.20 and an 8dbi 2.4GHz Wifi Antenna which cost around US$2. All of these parts can be easily found in online marketplaces like Aliexpress, Amazon, etc. Here is how you need to wire them up together. How you wish to lay this out or mount on a prototyping board is entirely up to you. As long as the connections are correct, you are good to go. The GPS module is optional, and mainly, it's used for the war driving functionality.

Next, you need to download all the firmware needed from here. Please download the Bootloader, Partitions, Boot App and Firmware files for v4 (Yes, v4 files, not any others) and save it on your computer.

Now, press and hold the BOOT button on your ESP32-WROOM-32U module and connect it to your computer using a data-capable USB cable (some USB cables can only charge), then let go the BOOT button. Open Google Chrome or Microsoft Edge browser and go to ESPWebTool. Click the CONNECT button, then select the ESP32 usb serial connection. It should look something like below but can vary a little between different computers and operating systems.

Select the firmware files for each slot exactly like below (take note of the 0x1000, 0x8000, etc. and their corresponding .bin files), then hit the PROGRAM button.

When completed successfully, you can unplug the USB cable from the ESP32 module and now you can connect your Marauder module to your Flipper Zero. Please ensure that your Flipper Zero is turned off before you connect it, and also turn off your Flipper Zero before disconnecting it. The 3.3V pin is also used by your Flipper Zero's SD card reader and connecting/disconnecting external modules that use this pin while the Flipper Zero is on can potentially corrupt the SD card. So, if everything went according to plan, your Marauder module should boot up and everything should look like below.

NOTE: If your Marauder boots up, but when you try to touch the screen and get no response, try tapping around the bottom part of your screen and see if the touch panel seems to be in inverted position from the actual display. Should this happen to you, just flash your ESP32 module again following the steps above, but use the v6 firmware. This should resolve the issue.

In this build, I just prototyped this on breadboard, but you can of course make it permanent by soldering it on to a prototype board and 3D print a case for it. This setup is essentially just using the Flipper Zero as a battery pack, instead of using the Flipper Zero to control Marauder. The large screen does make some things easier to do, compared to the small screen of the Flipper Zero, and there may be some functionality (not much) that is not currently in the Flipper Zero Marauder companion app. Here is a video showing the different menus in Marauder.

Personally, I don't think I will actually want to bring something so big around with me, along with my Flipper Zero. I think what makes Flipper Zero special is just how compact it is and all the different functionality cramped into it. This would probably be better off as a standalone unit by just hooking up a battery, but that's just me. Well, that's it for this tutorial. I hope you found this helpful.

Here's a good intro to Marauder if you are unfamiliar.
