Onkyo TX-2000 no sound?

[CT Jim]

But it did!!!! Unfortunately, the shelf gave way and the unit fell about 2.5' on the right side, which leaves the transformer on the upper end. Unit was off, cold not having run for a few days, and did work fine. Now the faceplate lights work, and that's it?

Now, no sound both channels???? There is one STK-463 IC module. Can this module take a shock like that? I have not pulled it yet, and so far there is no apparent damage.
Can transformers take a shock from a drop? Open to suggestions before I go further!

Check your mainboard carefully for any cracking.

I will be doing that saturday, I do have the tools and wire to repair if I find a break. And if so, I can only imagine how many traces I'll need to fix.
All shelves have been checked so this won't happen again!
