Lite On 9345c , Maybe Fried And I Need The Key
« on: November 26, 2011, 01:02:00 AM »

Hi guys i have a big problem with my PBC, The ck3 did a short-circuit and "killed" my drive. The problem is that i have to extract the key , because this happened before extracting the key  sad.gif .
I took some photos of the pbc, it doesen't looks quite destroyed.Maybe i can do something to extract the key .
I tried to check the r207 resistor with continuity mode (with the tester) and it looks OK.

Here are the photos:

solder all those pins together and ground them.  you may have to install a new r707.  i think it is 100k.  u can jump one like i did in the following pic.

When u say "ground them"  , what is that?

Now, the laser seems to works, but the chip on the pbc gets hot ... So i think it has a short.circuit on the old mra hack they did

You could always just buy a new dvd drive PCB and do the reset glitch hack if all else fails.
