This tutorial is for Sony KD-49X8300C TVs. For other Sony TV models, refer to this tutorial.
Installation process
1 Download the sofa butler installation file to the U disk → 2U disk connection Sony KD-49X8300C → 3 local playback Open the installation file → 4 installed successfully
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. Connect the U disk to the Sony KD-49X8300C TV, and then enter the main interface of the Sony KD-49X8300C.
3. Find security and restrictions on the main screen.
Click the Unknown Source option and click Open.
4. Return to the main interface, enter the application assistant, read the contents of USB1
Find the sofa butler apk installation package that was previously put into the USB flash drive (Note: If you had previously installed the sofa butler's APK installation package into the USB flash drive, but you did not see the installation package in this step, please format the USB flash drive. Or replace a new U disk again)
5. Complete the installation.
6. After the installation is complete, click "Open" to enter the sofa butler interface to quickly install all types of TV applications.
Open the display sofa butler interface, indicating that Sony KD-49X8300C has correctly installed the 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.

Via In Pad PCB
What is Via In Pad? In shortly,via in pad is the via holes are at the SMD pad.The vias are very small,usually under 0.3mm.Why and how? First is there is no enough space to layout,you have to put the vias and holes closer even together.Second it helps thermal management and for high frequency boards,it may help improve signals.
Because the SMD pads are for SMD components loading,so the solder can not flow to inner layer or the other side when assemble.That is the most important for via in pad board.
How PCB manufacturers like us to do via in pad board? We will fill all vias with non-conductive epoxy and plate copper over it ,so the vias are flat same as others. Many PCB factories are unable to do such capability.
The key technology is how we fill vias and guarantee there is no any solder (surface finishing) in the holes.
Filled via in pad is a way to achieve intermediate density with an intermediate cost compared to using blind/buried vias. Some of the key advantages associated with using the via in pad technology are:
.Fan out fine pitch (less than .75mm) BGAs
.Meets closely packed placement requirements
.Better thermal management
.Overcomes high speed design issues and constraints i.e. low inductance
.No via plugging is required at component locations
.Provides a flat, coplanar surface for component attachment
Via in big pads are not a big problem.but for BGA,that is technology.As BGA pads are very small,10mil or 12mil,and there is no enough space.Manufacturing is not easy as other boards.
