Trouble with your Projecta LCD Control Screen not working in your caravan? Follow this easy guide to diagnose, replace and get it working. Projecta LCD Control Screens are the primary interface between users and their power management units in Australian caravans and motorhomes. Like any electronic device, these screens can develop faults over time.

Is your Projecta LCD Control Screen not working properly?

When your Projecta LCD Control Screen develops faults like unresponsive power buttons or display issues the solution is usually a replacement screen. We sourced ours through Projecta’s excellent warranty service. From my research Projecta LCD Control Screen problems are generally fixed by replacement rather than DIY repairs.

Understanding Projecta LCD Control Screen Issues

One of the most common issue involves unresponsive power buttons – that’s what happened to ours. Some users may experience display problems, communication errors, or complete screen failures. Understanding these problems helps caravanners identify when their Projecta LCD Control Screen requires attention.

• Power buttons become unresponsive despite the system functioning through mobile apps
• Screen displays show distorted information or fail to illuminate
• Communication errors between the screen and BMS unit appear as error codes
• Temperature related issues from extreme Australian heat conditions

Safety Precautions

Before replacing your Projecta LCD control screen we need to make sure we’re doing it safely. Working with caravan electrical systems, even 12v ones like I did requires careful attention to safety:

• Disconnect all power sources before beginning replacement work
• Ensure battery isolation switches if installed are OFF throughout the process – otherwise disconnect the battery or batteries from the system
• Use appropriate personal protective equipment
• Ensure completely dry conditions before handling the new screen
• Avoid working during rainy conditions or high humidity

Power Isolation Procedures

Proper power isolation prevents damage to both old and new units:

1. Locate the main power switch on your BMS transformer unit
2. Switch off the unit completely
3. Disconnect battery power using isolation switches
4. Wait several minutes for capacitors to discharge safely
5. Test circuits with multimeters to confirm complete power isolation

Turning Power Off At The BMS

Tools Required

• Small flathead screwdriver for removing dress rings
• Phillips head screwdrivers for mounting screws
• Clean workspace
• Proper lighting
• Anti-static precautions

Removing The Faulty Screen

1. Ensure complete power isolation
2. Locate the dress ring surrounding your existing screen
3. Carefully insert a thin blade behind the dress ring
4. Apply gentle pressure to release retaining clips
5. Remove the dress ring to expose mounting screws
6. Unscrew the four mounting screws
7. Carefully disconnect the communication cable by grasping connectors (not wires)
8. Note cable orientations for proper reconnection
9. Remove the faulty screen from its mounting position

Installing The Replacement Screen

1. Remove all packaging materials from the new screen
2. Remove protective films from the replacement unit
3. Inspect the new screen for shipping damage
4. Remove the dress ring from the replacement unit
5. Position the new screen to align mounting holes
6. Connect the communication cable securely
7. Install the four mounting screws using diagonal pattern tightening

9. Install the dress ring by clicking it back in place

Reconnecting Power And Testing

1. Reconnect battery power using isolation switches in ON position or reconnect the battery or batteries
2. Activate the BMS unit’s main power switch
3. Your replacement screen should illuminate immediately
4. Test all button functions to confirm proper operation
5. Verify power button works correctly (press for on, press again for off)

Reconnecting To Mobile Apps

New screens require fresh Bluetooth pairing with mobile devices:

1. Download the latest PM200 & 300BTJ Remote App from your app store if you don’t have it already
2. Ensure Bluetooth is enabled on your device
3. Look for the pairing code in the top-left corner of your new screen
4. Enter this code into your phone app (not the serial number on the back)
5. Verify battery type and capacity settings match your specifications
6. Update system firmware if prompted

My Thoughts On Projecta Customer Service

Projecta customer service is awesome. Ours would have been one of the very early Jayco All-Terrains with these in them. When I contacted Projecta with a couple of previous problems they helped me out and got the problem sorted very quickly.

So once again Projecta have been very good to deal with. Fantastic customer service. I recommend them to everyone. Quentin and Ben Blood are both absolute legends. Great service and a big “thanks mate” to you both.
