What are the reasons and solutions for the white screen when the industrial control LCD screen is turned on?

LCD industrial control LCD screen is now one of the devices that can be seen everywhere. Industrial industries have gradually used industrial control LCD screens, and industrial control LCD screens occasionally have white screens. So, how to solve the white screen failure of industrial control LCD screen? It is a very common phenomenon that the LCD industrial control LCD screen turns on the black screen or blue screen. Black screen and blue screen are problems with the system or hardware, and the white screen failure of the display screen when it turns on is generally a failure of the LCD industrial control LCD screen itself.

Causes of LCD industrial control LCD screen failure:

The white screen failure of LCD industrial control LCD screen may be caused by three aspects: problems with the LCD panel drive circuit, problems with the LCD panel power supply circuit, poor contact of the screen line, and problems with the motherboard control circuit.

If the industrial control LCD screen can be turned on normally, it means that the backlight and high-voltage generation circuit are working properly, indicating that the LCD panel has not received the drive signal; if the screen disappears after shutting down, and then a white screen occurs, it may be a problem with the power board.

This means that no matter whether it is turned on or off, as long as the power is plugged in, the high-voltage generation circuit is in working condition and the backlight source is always lit. That is to say, the high-voltage generating circuit is no longer controlled by the switch, that is, the switching signal sent by the motherboard to the high-voltage generating circuit has lost control. Since the switching signal sent by the motherboard microprocessor is generally controlled by several transistors, the fault may be that the transistor that controls the switching signal is damaged.

LCD industrial control LCD screen fault repair:

1. Remove the shell and check whether the screen line interface is loose or not connected properly.

2. Then turn on the power switch and use a multimeter to measure whether the power supply voltage of the screen line interface is normal. If the power supply voltage is normal, check whether the timing signal and drive signal in the LCD panel drive circuit are normal; if not, then check whether the fuse resistor or fuse inductor near the output end of the screen line is open or damaged. If damaged, replace the damaged components.

3. If the fuse resistor or fuse inductor near the output end of the screen line is normal, then check whether the output voltage of the DC-DC voltage conversion circuit that powers the LCD industrial control LCD screen is normal. If the output voltage is abnormal, check the fuse resistor, PWM controller, switch tube, inductor coil, filter capacitor and other components in this power supply circuit, and then replace the damaged components.

4. If the output voltage of the DC-DC voltage conversion circuit is normal, there are damaged capacitors and other components between the output of the DC-DC voltage conversion circuit and the screen line interface. Check and replace the damaged components. 5. If the power supply voltage of the screen line interface is normal, then check whether the timing signal and drive signal in the LCD panel drive circuit are normal. If not, check the output signal, input signal and power supply voltage of the chip that generates this signal to determine whether the drive chip is damaged. If damaged, replace it.

Another 2022-present portable computer thing. This is a 1991 Corvallis Microtechnologies PC5-L. It's a ruggedized, waterproof handheld MS-DOS computer meant for industrial applications. It ran on Ni-Cd batteries and they died so now it runs on AA's I got two of them for $50 on eBay during one of those months when i impulse buy obscure electronics as a form of escapism This thing is an absolute brick. You could murder someone by hitting them on the head with this, and it would work fine afterwards. Here's pictures of its organs for anyone curious:

That thick red wire around the screen PCB is a heater. Yep there's a setting to heat up the LCD so it doesn't get sluggish or shatter when you decide to leave it in the freezer. The thing runs on a little system-on-chip thing, which is interesting to see coming from the early 90's. Iirc the datasheet says it's capable of analog video out as well as driving the LCD, but I haven't poked around enough to enable it. Might be cool to hook it up to a TV. I did, however, open those 512k storage modules and I saw some unpopulated footprints on the boards. So I ordered some of the same chips, and at some point I'mma try soldering them on and see if it recognizes the extra space. They came with two voltmeter modules, which I couldn't get to work, so I took one of the casings and made it into a USB and WiFi adapter using an ESP32 running Zimodem, since this thing has RS232 ports on the top. I also made my own charging adapter, since they didn't come with one. I see that internal PCMCIA slot, and I tried putting a CF card adapter in, and tried installing the drivers, but it didn't work. I'm not good at DOS tbh, and I know nothing of what this slot is for. I might come back to it later. I did all of this in 2022-23 and haven't messed with it since. Except to use it to talk to my Kaypro 4 '84:

More on that one later. I love portable computers !!!!!

Gundam Calibarn watch!

Been hit hard by the Witch from Mercury brainworms lately, so when I first saw this junker watch for sale I thought it could make for a fun gundam project!

The watch looked fine in the sale listing, but its actual condition wasn't great- the spring bars holding the straps had rusted and gotten stuck, and the straps had to be cut away to access and dislodge the bars.

The gasket had also melted, and the inside of the casing was covered with some sort of fishy-smelling residue. Thankfully though, the main watch module was still functional.

It took a good while to clean everything up and buff out the scratches, but once that was done I could get started on the customisation!

First off, the old yellowed straps were replaced with a fresh white silicone strap to match the calibarn. I also designed a custom sticker for the watch face based on some gundam decals. It took many attempts to apply the sticker without air bubbles forming, but the final result was worth it!

For the permet effects, I cut up some rainbow holographic film and applied it the lcd screen. The effect is subtle most of the time, so the watch is still easy to read. However, it shines beautifully when it catches the light!

All in all, I'm pretty happy with how this project turned out! The total cost of the watch + materials was much cheaper than if I had gotten the same watch brand-new, and it's always a great feeling to clean up something old for use again.

If you want to try making your own, I recommend using a junk/secondhand watch for this - I nearly broke my watch fiddling around with it, so please don't do this with anything expensive! There are plenty of tutorials on youtube for any customisations you want to make, so explore around and see what works for you!
