About A24  Wireless screen projection function

          wifi-display function, the projector displays the image and sound of the mobile phone screen through the mirroring function of the smartphone. This is not achieved using the Bluetooth function. It is achieved through the screen mirroring function that comes with the phone.

          Operation instruction video connection:https://youtu.be/GvPwHOPKnuc

          Note: Not all Android smartphones support the screen mirroring function. For smartphones that support screen mirroring, there are options similar to this in the “Settings” or “More Functions” options of the smartphone, for example: “Screen mirroing”, “Wifi-display”, “multi-screen”, “screen projection”, “play to”, “media output”, etc.

          If the projector’s pre-installed screen mirroring app is not compatible with your Android smartphone, you can also download and install Airscreen, happycast and other apps that support wifi-display on the projector.

Tips：

          Some video apps with copyright protection cannot support wireless projection from other devices to the projector. For example, Netflix, iTunes Movie, Google Movie, Amazon Prime do not support this function on some smartphone and computers. All Android system projectors on the market are the same.

A24   Projector Maintenance Guide

  1. How to solve the problem of remote control not working?

        1.1 The projector comes standard with a 2.4G wireless remote control. If the remote control does not work, you need to re-operate the remote control to pair with the projector.The operation method is to take out the battery of the remote control, start the projector, wait for the projector to turn on, then move the remote control close to the projector, and then install the battery of the remote control, and the remote control will re-pair with the projector.

        1.2 If the pairing is unsuccessful, replace a remote control and try again.

        1.3 If the replacement of the remote control still fails, it may be that the cable between the remote control receiver and the motherboard is loose. Reconnect the cable between the receiver and the motherboard.

        1.4 If there is still a problem, there may be a problem with the remote control receiving circuit board or the main board. Just replace the corresponding parts. There is a disassembly video guide below.

  1. The lens of the BYINTEK A24 projector has no light coming out, and the LED does not work, how can I solve it?

           Fault phenomenon:

           After the projector presses the power button, you can hear that the fan inside the projector is working normally, but there is no light coming out of the lens at all, maybe the LED is not working.

First, disassemble the projector to check whether the cables on the power board are connected properly. If the cables on the power board are connected normally and there is no looseness, the projector still does not work, and a new power board needs to be replaced. If it is still not normal, you need to replace the LED. If the lens still has no light after replacing the LED, you need to replace the motherboard.

Usually replace the power board projector is normal. LED damage is generally caused by high voltage breakdown of the projector’s LED due to lightning strikes or unstable household power grids.

  1. Replace the power board of BYINTEK A24 series projector

           Fault phenomenon: 

           The power indicator on the top cover of the projector is not on, or there is no light coming out from the inside of the projector lens (that is, the LED does not work), it may be a problem with the power board, and the power board needs to be replaced

           Operation instruction video connection: 

  1. Replace the focus motor of BYINTEK A24 series projector

           Fault phenomenon:

           If you press and hold the “F+” and “F-” buttons of the remote control, the projector lens cannot move back and forth, that is, it cannot be focused. It may be that the focusing motor is not working, or the circuit board connected to the focusing motor is not working. Replace both parts.

  1. A few minutes after the projector is turned on, a black shadow appears in the middle of the screen and gradually expands. This may be because the LCD cooling fan inside the projector is not working.
