I want to hack my Samsung DVD player. But the IC used it a Sanyo LC87F5NC8A. I don't have a programmer that can dump or program this UC. Any advice ??

The datasheet is available via Google. Page 4 has lists part numbers for Flash ROM programmers that can program the chip.
Here's one company that makes them: http://www.j-fsg.co.jp/en/index.html
They don't appear to sell the exact models listed in the datasheet, but the AF9709C looks like it might do the job. I bet it's expensive, but you might be able to find out how it operates it, and then emulate it with something cheaper.

\$\begingroup\$ Sorry, mjh2007, I didn't even notice your answer when I amended mine. I was just responding to davr's comment above. But I'll upvote you all the same. \$\endgroup\$pingswept– pingswept2010年04月27日 20:31:17 +00:00Commented Apr 27, 2010 at 20:31
The programming algorithm should be in the documentation for the chip. You could implement it on another MCU.
I found the datasheet by doing a Google search for the part online. In the datasheet it references a number of different programmers to use with that chip.
You could buy a different DVD player which somebody else has already hacked/reverse engineered. In terms of effort and time, that's going to be a lot easier.
