U4 Quad Hybrid Android TV Box Unboxing and Teardown with DVB-T2, DVB-S2 and ATSC Tuners

Yesterday, I wrote about U4 Quad Hybrid Android Digital TV receiver based on HiSilicon Hi3796M processor, and supporting for DVB-T2/T/C, DVB-S2, and ATSC standards. Today, I’ve received the device, taken a few pictures, and torn it down to find out more about the hardware. The full review will come out in a few weeks.

U4 Quad Hybrid Unboxing

DHL did their job quickly as I received the set-top box in about two days in the following package.

The box comes with a 12V/1.5Am AV and HDMI cables, a WiFi antenna, an IR remote control requiring two AAA batteries (not included), a user’s manual in Korean language only and… a separate tuner…

So let’s check that tuner more in details…

The demodulator chip is LG3390A, so an ATSC tuner is included in the package. Not very useful in Thailand, but it’s good to know it’s included. I also open the cover of the bottom connector.

And if I’m correct, what we have here is Aihora AV2012 DVB-S2 tuner chip, so that little expansion board should support both ATSC and DVB-S2.

The box itself look fairly nice. We’ve got a USB 2.0 host port and a a USB 3.0 host port on the side (both limited to 500 mA), as well as a micro SD slot, the AV port, and a mini USB port for an IR/LED extension cable (not included). The rear panel features ANT IN and LNB IN antenna connectors, coaxial S/PDIF, the WiFi connector, HDMI output, 10/100M Ethernet, and a power jack for the 12V input.  If the antenna ports do not mean much to you, a look to the Korean user’s manual may help, as ANT IN is referred to “Ter In” and LNB IN to “Sat In”, which should be the left connector if for DVB-T2/T/C and the right connector for DVB-S2/T2, and if you want ATSC + DVB-S2, you simply need to insert the ATSC tuner. The sad part is that doing so would void your warranty according to the sticker on the rear panel… So I don’t really get it.

You could also watch the unboxing video for something more visual.

U4 Quad Hybrid Teardown

You’ll need to remove three screws to open the device. The one on the rear panel above the HDMI port, and two on the bottom of the case.

There’s a sticker in Korean on the bottom about Shenzhen Sosci Technology, which specializes in, you guessed it.. LED aquarium lights! I’m not sure if there are other companies with the same name, and I picked the wrong one, or they simply chose to diversify. The MAC address suffix 00:11:AD points to Shanghai Ruijie Digital Technology, an Internet service provider, and the company that actually sent me the product is called Shenzhen Vivant Technology, so lots of parties involved here!

The board called W96M_MAIN VO.4 feature the HiSilicon processor with a heatsink, an 8GB FORESEE NFEFEH68-08G eMMC flash, two SKhynix H5TQ4G63AFR DDR3 chips (2x 512MB), and Realtek RTL8188ETV Wifi module.

If we zoom in on the tuner area, we can see AVL6762TA DVB-T2/T/C demodulator, and on the main board itself and located on the bottom right of the picture above, Hisilicon Hi3136 is the DVB-S2/S demodulator.

There’s also two LEDs, an IR receiver, and a 4-digit LED panel on the front of the board.

There’s basically nothing on the bottom of the board, except S1 switch which should be the firmware recovery button.

I’d like to thanks Shenzhen Vivant Technology for sending a review sample, and you contact them if you wish to purchase in quantities. They also sell U4 Quad Hybrid for $119.99 shipped by DHL on Aliexpress, but a cheaper option is to go with China Post for $106.69 instead.
