LG 32LX4DC buttons don't work

[MRX37]

Found an LG 32LX4DC today on the curb. Almost didn't bring it home, decided to anyway just to see what's wrong with it.

I expected the set to be dead, either bad caps or a bad board in it. To my surprise, plugging in the set makes it turn on and the screen, apart from a nasty scratch, works fine.

But the front panel buttons don't work. Power, channel, volume. None of the buttons do anything.

I've already taken it apart to see what's what. tried reflowing the soldering on the button and remote control boards, no effect. Wondering what the issue could be.

Also wondering if it's worth my time to fix it. It has some things going for it and against it.

CONS:

Screen has a deep scratch.
No HDMI
720P resolution

PROS:

Very well built, with the weight to back it up. 55 pounds worth. Thick, solid metal both for the stand and inside the TV. LG did not go cheap when making this TV!
No apparent bad caps.
Some unique features such as two VGA ports.

I don't really need it, but it's not often I find an LCD TV, much less one that doesn't have a cracked LCD.
