Hey guys��
I purchased a crossfire VR4000D used, I went to the guys house to test and pick it up, When I got there to test it he said he could only power it up and could not shoe output due to no source unit.
Anyway he powered it up, Power light lit up blue, Internal fan started spinning, and I also heard the relay inside click after 3~4 seconds. So I packed the amp and brought it home.
Next day I put it on the bench to test its output. And just my luck nothing!. Power light was on, fan was spinning and relay clicked. So I opened the amp up and found some very nasty burnt mess.
I took a few pics to see if anyone knows what part exactly had blown as its hard to see as its all so burnt.

Probably EVA is right.
Try to completely clean the toasted area, most likely it is just a conductive piece that touched the feet of the transformer, causing a nice blaze.
I believe that once the area is cleaned up, all the components that are now blackened will come out intact.
Only then, can you power up the amplifier and check if at least the power supply works and generates all the necessary voltages, then we can go to the troubleshooting for which the amplifier does not emit sound.
Also, I suggest you publish this topic in the "car audio" section where many experts can help you.
