Default Re: yet another "what player is this" - I've got c

Ok, so I bit the bullet trying to figure out what hardware was under the hood and removed the back of my player. Here's the numbers I wrote down from all the chips in the unit and what I could find out about them

samsung K9HCG08U1M - NAND flash
Winbond W9812G6GH - SDRAM
RK2706 (we know this)
LN4890 - no idea - no name (i'm assuming it's some kind of opamp based on chip designation - but most i've dealt with start with LM)
JST916T - touchscreen possibly? - another no-nane chip
5800C - no name chip. DAC...FM?

*edit: the LN4890 seems to be an opamp...however, I can find no datasheets. The JST916T is a touchscreen controller...verified by an archived posting on this forum. The 5800C is the mystery chip. I cannot find ANY information about this chip anywhere. no datasheets, nothing. I also think I'm missing a chip or two becuase there SHOULD be some kind of FM radio chip in there. Is it possible they snuck things under the LCD?*
