Main lcd not working.

My player can do everything it should,but there is no display at all. Are there any internal fuses, or does anyone have a circuit diagram. Any help would be great.Have taken the back off the display to see if there are any loose or dry joints but it looks ok.

If the unit is a flip face then suspect the ribbon cable to the main circuit board from the front display. If it isn't a flip face then suspect that the back light lamps are out. If you can see a very very very dim image of the display when it is running then for sure it is a back light problem.

Where is the 5 amp fuse providing 12 power to the display on thetford fridges

The 5-amp fuse that provides 12V power to the display on your Thetford N180 fridge is most likely located in the main fuse box. Some Thetford fridges have a separate fuse specifically for the display, but others use the main fuse for power to the display and other components.
I would recommend checking the main fuse box again to make sure that the appropriate fuse is in place and that it is not blown. If it is in place and not blown, you can check the wiring leading to the display to ensure that there are no loose connections or damage to the wires.
If the fuse and wiring are fine, the issue may be with the display itself and it may need to be replaced. If you are not confident in troubleshooting the issue, it is recommended to seek assistance from a qualified technician.

2001 Honda Cb 400 Super Four no instrument display

If the LCD display for the clock and fuel gauge is not working on your 2001 Honda CB 400 Super Four, there are several potential causes and steps you can take to troubleshoot the issue:
  1. Check the Fuses:
    • The first step is to check the fuses. A blown fuse could be the reason why the display is not working. Locate the fuse box (usually under the seat or near the battery) and find the fuse responsible for the instrument panel. If it's blown, replace it with a fuse of the same rating.
  2. Inspect the Wiring and Connectors:
    • Loose or corroded connectors can also cause display issues. Carefully inspect the wiring and connectors leading to the instrument panel. Look for any signs of wear, tear, or corrosion. Clean and secure any loose connections.
  3. Check the Battery and Charging System:
    • A weak or dying battery might not provide enough power for the instrument panel to function properly. Check the battery's voltage and the bike's charging system to ensure everything is working correctly.
  4. Inspect the Instrument Panel Itself:
    • The problem could be with the instrument panel itself. This could be due to internal faults like a bad LCD display or other electronic issues. In such cases, the panel might need to be professionally repaired or replaced.
  5. Look for Grounding Issues:
    • Poor grounding can cause various electrical issues on motorcycles. Ensure that the ground connections are clean, tight, and free of rust or corrosion.

It just wont power up

If you get any power lights, or LCD display, then it is possible that the main processoer could be locked up do to a small power supply. If nothing works, then check for a blown fuse on power supply , or a bad power supply.

Problem on the main display screen on my Nokia 6085

Sounds like a bad lcd flex cable, i fixed mine by ordering the part from an international parts carrier, but if you are not technically inclined to open up your phone and possibly destroy it, i would not recommend it.

Main LCD display doesn't work!

This is a tricky one. There is a very small/thin ribbon cable which connects the LCD display to the main board. If this shifted, or came loose - highly unlikely, but possible - it might explain the issue you are having.

You will have to open it up to see if anything is loose, or not properly connected.

Or, I would suggest taking it to a qualified service center for repair. If the LCD is not damaged, shouldn't be too expensive. If the LCD just burned out, then look to spend about US$120-160 for the repair, including parts.

Face Plate

If this is a "flip face" type of display then you may have a broken lead in the ribbon cable that connects to the main board from the flip face. This is a very common problem. You'll need to replace that ribbon cable.
