I just got this off eBay in new condition.
The power inlet looks very different - it's a micro square socket I think this was intentionally done to prevent the user getting confused as to which power supply goes to what. The power plug also says "Audio equipment," which is a little unusual for an audio/video apparatus. Power supply for an SPDIF-based Dolby speaker system, maybe?
The box uses no screws. I opened it up by using a pry bar set I had bought to fix a friend's Zune.
Opening it up shows lots of chips. Taking the lid off the tuner shield shows a chip, a loop coil. two crystals, a resistor IC and various small parts. The tuner chip is a MT2131F 0JH370023G There are posts inside for a legacy style tuner.
The Flash memory is an 8x8 Spansion S99-50048, possibly 512 MBs Lots of room for a good GUI and a catalog of channels with methods for accessing and storing extended channel guide information.
The work memory is a Hynix HY5DU121622DTP-D43 64 MBs DDR Not a lot of memory.
The main CPU chip is a ST STi7707WUDP, The
ATSC decoder chip is a ST STV0373.
There's headers for a 4-pin connector, and a 2-pin jumper
On the bottom there's another unknown 7x7 solder-ball mounted chip It has no markings other than 156054 D822 and the A1 marker dot. There is probably info on the other side (sometimes the case with certain chips like these (from past experience with EEPROMs,) but I'm not sacrificing this
DTV converter, but another board suggests that it's a substitute for a subscriber card in a Dish Network box.
The remote control looks pretty heavy-duty with its twin-IR transmitters. It comes preloaded with batteries. It's nice, but not very safe.
There have been reports of this box responding to the remote control of an Echostar Dish Networks box, and vice versa. (the remote says Dish Networks on it)
I'll add to this when I receive the one I bought from a consignment shop - the eBay ad said it was broken, so I got it really cheap. "Item powers up but the setup returns an error state." With any luck, it's in perfect working condition - it was the antenna setup that was no good.
Don't have any time tonight to review it. I got to get to my work early tomorrow morning.
