Not sure anyone will care, but I just got and disassembled the USDTV HT-7012. This is the 'father of the DB2010' (what they used to use). This unit is thinner and heavier than the newer, more common unit most often discussed here. It still works perfectly, but of course has ancient firmware. I'm thinking that the later firmwares wouldn't work with this unit, as the hardware is likely different... feedback, anyone?
Anyway, here's a bunch of random info about it.Model No. HT-7012 Teardown Info:
This unit, once open, has four basic parts inside. The power supply is a U-San Electron 3.3 Vdc/7A, 5Vdc/1A. Using a non-standard molex connector, it hooks into the main board (labeled 10-0184 USDTV-V1.2). The main board runs an ATI Xilleon 225 (X225 215H25AKA13 N01839.00 0316AA) graphics processor, and has five Samsung 340 flash chips (4 x K4D261638E-TC50, 1 x K9F2808UOC YCB0). This board also has two
USB ports, a bunch of unused component spots, and some test points. The smart card header is
actually connected to a smart card module (10-0185XSM TUNG_TA S-02 94V0) in this unit- unlike the DB2010, which has the external slot but is missing the innards.
The last part is the tuner itself- a dual-port Philips tuner (3139 147 20231C#, TUV1236D/F H, SV10 0343) mounted on a small board (labeled 10-0168) that connects to the mainboard by a standard 40-pin IDE plug. Don't get too excited- I'm sure it has nothing to do with actual IDE, they just utilized ready-made parts to cut costs. What's more interesting to me is the headers, jumpers, and even a microswitch pad that aren't in use on the mainboard. And being dual port, wouldn't the tuner work as a pass-through as well?
I realize not everyone has this older model, so may not think this relevant. However, I believe that alone is worth posting this; if for no other reason than to help inform the few people that do
Plus, I've got this unit and two or three DB2010 (firmware says DB2020) receivers now just waiting for me to do something with them
! If anyone has requests for other/better/specific internal pictures on either model, let me know and I'll provide it. Creating documentation is something
