Not starting

If your BioCon 750 is not starting, but the power light is lit, this suggests that the device is receiving power but is not fully initializing or operating correctly. There are several steps you can take to diagnose and potentially resolve the issue:

1. Check the Power Supply and Connections

• Verify the power cord: Ensure that the power cord is securely plugged into both the device and the power outlet. Sometimes, the power cable may look connected but could be loose.
• Test the power source: Try plugging the device into a different power outlet to rule out issues with the electrical outlet.

2. Look for Error Messages or Codes

• Check for any displayed error codes on the screen (if applicable) or indicator lights that might give you a clue about what's preventing the unit from starting. Some devices display specific codes when there’s a malfunction.

3. Perform a Soft Reset

• Turn off the unit completely (if not already off) and wait for a minute or two.
• Turn the unit back on to see if the issue clears. Sometimes, performing a reset can resolve minor software or internal glitches.

4. Inspect the Display Panel

• Test the screen/display: If the light is on, but there is no other sign of activity (like the display not turning on), there could be an issue with the screen or internal components like the motherboard.
• Look for any backlight: Is the screen completely blank, or is it just not displaying content? A completely blank screen could indicate a power supply issue to the display.

5. Check the Fuse

• Inspect the fuse of the BioCon 750. Some devices have an internal fuse that can blow due to power surges or internal electrical issues.
• Replace the fuse: If the fuse is blown, replace it with one of the same rating as specified in the user manual.

6. Examine the Internal Components 

• Loose connections: Open the device and check for any loose wires or connectors. Sometimes, internal connections may loosen, especially in high-vibration environments.
• Overheating: If the device has been running for extended periods, it could be overheating. Allow it to cool down and see if it starts after some time.

7. Verify Internal Battery (if applicable)

• Some models of the BioCon 750 may have an internal backup battery that helps maintain memory settings. If the backup battery is dead or low, the device might not start properly.
• Replace the battery: If you suspect this is the issue, check for the battery in the device and replace it.

8. Software or Firmware Issue

• Firmware corruption: Sometimes, software or firmware issues can prevent the device from starting properly. Check if there are any firmware updates available from the manufacturer or service provider.

If you just re-asembled the device: Most likely the slimest flat cable to the display, this cable easly come loose when you reasemble the motherboard to the screen.
