2016 Nautique G23 Screen Fading and Glitching? The HV700BP Fix (PN 78350617)
The screen at the helm of the 2016 Nautique G23 fades out, starts glitching, and touch response becomes unreliable. This is the Murphy HV700BP display, and these exact failures are among the most common issues we see on Nautique LINC 2.0 boats. Here is what is happening and how to fix it.
In this guide
- What the HV700BP is and how it differs from the standard HV700, plus the part number it carries
- The 4 failures we see most: fading LCD, glitching display, unreliable touch, and ghost touch
- Why the OEM backlit LCD degrades and how to remove the display
- How we replace the defective OEM components with brand new parts and fix yours for less
What Is the Nautique G23 HV700BP?
The 7 inch Murphy backlit LINC 2.0 display
The 2016 Super Air Nautique G23 uses the Murphy HV700BP at the helm, the backlit panel variant of the 7 inch HV700 platform. Built by Murphy / Enovation Controls, it is the brains of the LINC 2.0 system, controlling ballast, speed, engine data, fuel, audio, and navigation through a single touchscreen. The same platform is also found on the G21, G25, 230, and 210 Nautique models from the same era.
The HV700BP differs from the standard HV700 in its LCD backlight design, which is what produces the fading and glitching as the primary failure symptom on these units. Like the standard HV700, it is a mail-in repair only, the glass separation process requires specialized equipment.
Fits 2012 to 2017 Nautique G23, G21, G25, 230, and 210 models equipped with the LINC 2.0 touchscreen. If PN 78350617 appears on the rear housing of your display, this is the correct repair.
The 4 Most Common Failures
What goes wrong on the Nautique HV700BP
The backlit LCD panel and the touch controller are the two components that tend to fail first on the HV700BP. LCD degradation is usually the first thing owners notice, and touch problems follow.
🌓 Fading or Dim LCD
The display gradually loses brightness and color accuracy. What was once crisp and readable in direct sun becomes washed out, dim, or almost impossible to see during afternoon sessions.
📺 Glitching Display
Color bars, flickering, random visual artifacts, or sections of the screen displaying incorrect colors. The OEM backlit LCD develops these glitches as the panel and its connections degrade under years of heat and UV.
👆 Unreliable Touch Response
Taps land off-target, controls require multiple presses, or specific zones stop responding consistently. Touch problems tend to develop alongside the LCD degradation as the same aging process affects both components.
🔮 Ghost Touch
The screen registers inputs no one is making. Ballast settings change, menus open, and controls activate on their own. As the touch controller ages it becomes noise sensitive and floods the system with false signals.

Why the OEM LCD and Touch Fail
The defective OEM design, not user error
The HV700BP backlit LCD was not designed for what a Nautique helm sees over a decade of use. The same set of forces works against it every season:
- Direct UV at the open helm, full sun for hours every day degrades the OEM backlight components and the protective layers above the touch sensor grid.
- Heat cycling, the unit heats up during use and cools overnight, season after season. Repeated thermal expansion stresses the internal connections and the LCD panel components until they begin to fail.
- Aging touch controller, the internal capacitive touch IC becomes increasingly noise sensitive after five to seven years. Ghost touch and inaccurate response are the visible result.
- Marine humidity and vibration, hull vibration and condensation work on the internal connections over thousands of hours, accelerating the degradation of both the LCD and the touch grid.
How to Remove the Display
Standard hand tools, about 20 minutes at the helm
The HV700BP comes out of the G23 dash from the front as a complete unit. No heat gun, no dash disassembly, no specialty tools required.
- 1Disconnect the boat battery before any work at the helm. Pull the negative terminal first.
- 2Remove the mounting fasteners on the rear of the dash holding the display housing. Set the hardware aside to reuse.
- 3Disconnect the wiring harness from the back of the unit. The LINC 2.0 connector is keyed, so note which plugs go where before pulling.
- 4Slide the display forward out of the dash with the bezel attached as one complete unit and pack it safely.
- 5Ship it in with the prepaid UPS label we email after checkout.
