This tutorial is applicable to the TCL L40P2-UD. For other models of TCL TVs, refer to this tutorial.
[Installation process]
1 Download the sofa butler installation file to U disk / SD card → 2U disk connection TCL L40P2-UD → 3 Open the installation file through "Software Recovery" → 4 Installation is successful
ã€Steps】
1. Baidu search for "sofa manager" into the sofa network, download the sofa butler package; or directly click the link (http://app.shafa.com/shafa.apk) to download the sofa butler package.
Copy the downloaded apk installation package to the U disk.
2. Create a new folder in the U disk or SD card and name it "TVManager". In this folder, create a subfolder named "backup" and put the downloaded sofa butler apk into the backup (if you use the TV Existing SD card, you can directly find the backup folder).
3. Find a TV Guardian or TV Steward, open up and you will find there is a software management.
4. Click Software Management to enter Software Recovery.
5. Find the sofa butler, click "Install" or "Resume", after a few seconds will be prompted to complete the installation and then exit, you can find in the "Application" page or "all applications" just installed sofa housekeeper.
Open the display sofa butler interface, indicating that the TCL L40P2-UD series has been properly installed sofa butler, you can download any TV application you want in the sofa butler.
If you still cannot read the USB flash drive, you are advised to format the USB flash drive in FAT32 format first (if there is any other content in the USB flash drive, export it and then format it) or try another USB flash drive.
If the installation fails, restart the device and try again by following the steps. Still have questions please add the following sofa butler official QQ group.
Watch on-demand videos on smart TVs, recommend watching TV live broadcasts, and recommend HDP live streaming. For more interesting content, please use Tencent video TV, TV, Fun smart TVs and boxes, and more exciting content on the sofa.
Semiconductor Fuse And Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
