Introduction
The Jensen VX7020 was designed with RV enthusiasts in mind. Not only is it an innovative addition to any vehicle, but it also provides every necessity and luxury for those long trips.
Not only is it equipped with all the navigational know-how you could possibly need, but it is filled with extras from Bluetooth-connected integrated speakers to DVD/CV system for entertaining passengers,
Unfortunately, over time problems can occur even with state-of-the-art technology. For example, even the trusted Jensen VX7020 could develop issues with its touchscreen display, whether it is not turning on or not responding to touches.
If your device has incurred a fault, it is imperative that you get it back up and running before your next road trip. Therefore, this will be a valuable guide to help you find the problem and get it sorted before you head out on the road.
How to Fix Jensen VX7020 Touch Screen Not Working?
1. Display Won’t Follow Commands
With the abundance of touchscreen technology in our modern lives, it may be surprising how complex and challenging a task it can be for a computing system.
Tracking every compression and feeding that information through a CPU is a surprisingly arduous and complicated process.
Critically, a touchscreen must be able to track your finger movements incredibly accurately, considering the volume of icons and options available on the screen. However, you may have noticed that there is an issue with accuracy over time.
Even with the most pinpoint and deliberate touches, you may have found that the screen is doing something different.
In this instance, you are likely to be experiencing calibration issues. Essentially, your touchscreens input and the internal CPU can go out of alignment over time. It can result from CPU deterioration or improperly installed updates and a host of other sources.
To prevent your screen from having a mind of its own, you can perform a simple screen calibration to rectify this problem quickly.
Activating the calibration setting on your Jenson VX7020 is a reasonably straightforward process.
First, you must turn the screen off and back on. Then select the ‘Settings’ icon and scroll to the bottom of the list. Press the calibration option, and you will be given instructions on the screen that you can follow easily.
You will press the center of crosses on the screen that appears with your finger. It may seem like a strange process, but you are essentially setting new screen parameters that the Jensen can interpret and realign its display.
After you have completed the calibration cycle, you should conduct a few of your regular tasks, like setting up navigation and connecting to your phone. Now it should be taking your instructions more accurately.
Be mindful not to use any sharp objects like pens during the calibration process. It may feel like you will get a more accurate display, but you may unintentionally damage the screen instead.
2. The Screen is On But Unresponsive
If the screen is on, but the screen is not reacting to your inputs, then the system may have crashed. Although there are a number of potential reasons and sources for system crashes, most often, it is a result of an overloaded RAM chip.
It is considered an Achilles’ heel for many vehicle touchscreens, as they prioritize power efficiency over performance to allow it to be powered by the vehicle battery.
Unfortunately, this can happen from time to time and without much warning. Luckily, there is a reasonably simple solution. Performing a soft system reset will most likely resolve this issue immediately.
Conveniently, the display unit has a manual reset button located directly under the On/Off button. It is a tiny button that may require the tip of a pen to compress. Press the button for around 3 seconds.
The screen will go blank for around 30 seconds, and it should reboot on its own. Give it around a minute to calibrate and activate its internal systems. With any luck, you will not have your Jensen VX 7020 back up and running as expected.
Be mindful that if you have any stored Bluetooth connect phones or maps preloaded into the system may be deleted as a result of the reset. However, you can re-enter them into the system by following the on-screen instruction once the reset has been completed.
If screen crashes become a regular occurrence, you should consider having them inspected by a professional technician.
Soft resets are a very convenient solution to several other problems with the screen too. So if there is ever an unusual problem or screen issue, it should be your first port of call as an easy and effective solution.
3. The Display Will Not Turn On
Suppose you try switching the Jensen VX7020 on as normal but find the screen blank. This problem is not often associated with the Jensen itself. Instead, it is more likely to be an electrical issue. Fortunately, there are a few simple steps to assess this problem.
Confirm that your RV itself will turn on as usual. Try to start the vehicle and identify if there are any unusual symptoms.
If the vehicle simply does not turn over, you have found the source of the problem. It will most likely be your vehicle battery is dead, and it cannot provide power to your screen.
Alternatively, if the vehicle is struggling to ignite, there could be an issue with your vehicle’s battery condition. Over time batteries will degrade and not be able to produce the necessary amount of voltage to power all or its systems.
Therefore, the issue may be with the vehicle’s electrical power, which an automotive technician should inspect. The solution would be a simple battery replacement which should get everything functioning properly again.
A safety mechanism in all modern vehicles is a fuse box system. There are fuses for each electrical device within your vehicle, which are designed to break the electrical circuit.
They do this if too much power is pushed through the system, which could damage the component or overheat, setting fire to the wires themselves. The Jensen touchscreen is no exception. Consult your car’s manual to identify the fuse box location.
The Jensen is designed to be powered by the radio compartment electrical system. Therefore, the radio fuse location should be identified first. Replace the fuse with the same amp rating and attempt to turn on the device, even if it doesn’t appear damaged.
Replacing the fuse is a simple solution. However, if this becomes a regular occurrence, you should seriously consider having the electrical system inspected. Your Jensen may have been installed incorrectly, allowing it to pull too much power from the battery and damaging it over time.
Unfortunately, this is not an exhaustive list of electrical power issues associated with the Jensen. There could be a number of other sources, from fried circuitry, broken wires, screen issues, etc.
These issues are far more complex and challenging to resolve, so attempt the above solution first before you assume the worst.
4. Inconsistent Instruction and Murky Display
The Jensen is a superb addition to any road trip, providing easily programmed and clear instructions to keep you on the right roads. However, over these long distances, we can all be guilty of snacking on the road and not have the best washing solutions to hand.
Often, touchscreens that are not washed regularly can build up a coating of oil on the display unit. The oil build-up can be subtle and may only obscure the screen slightly.
However, a thick enough coating will eventually create a barrier between your finger and the screen, which begin to act as if it is malfunctioning.
The best practice is always to keep a clean and oil-free screen to ensure that it functions properly and looks as clear as possible. The best method is to use a damp cloth and a little dish soap to thoroughly wipe down and clear any residual oil from your hands.
Conclusion
When a problem occurs with your Jensen VX7020, it is imperative that you resolve it as soon as possible. It is a vital navigational and entertainment tool that is a necessary addition to any RV adventure.
Although some inconvenient problems can occur, reading this article will equip you with enough knowledge to identify and resolve them easily. Although there are a host of potential issues, you will likely find a solution from the list above.
