I found a previous thread about hacking Vizio TV's but I noted a lot of the folks trying to gain access were doing so through telnet or over the network. I just picked up a Vizio M551d-A2R, and taking a look at the mainboard on it I see a couple of un-populated headers that could be a serial and/or JTAG interface based on the traces and connector layout.
Anyone have experience with trying to gain write access to hardware via I2C or Jtag that could help a relative newbie hack his TV to pieces?
(Before you ask, I'm doing this more for the fun of it than any practical purpose, and who knows, maybe we'll see a Vizio TV section pop up on XDA if this goes well)
Technical specs on the TV:
(U20) Mediatek MT5590 (looks like a specially built version for TV's and I cant find a spec sheet)
(U4) Micron 16GB NAND (located on bottom)
(IC9/10) Nanya 128mb DDR3L x2 (256mb RAM total)
(IC11) Nanya 64mb DDR3L Ram
(IC4) EEPROM (cant read label properly)
(RN21) Unpopulated, looks like I'll need to add a bridge or jumper resistor here as it appears to be sitting on the I2C bus traces
(CN3) JTAG(?) header
(CN33) I2C Serial Bus header
