I have an Orion Cobalt 600.2. I recently plugged it in 24V by mistake. It didn't do any smoke (or fire). Since then, the output stopped working and the protection light doesn't go off (unless I unplug the Amp...). The power light doesn't go on, but, there is a blue light that goes from the right side to the left side that is on although the power light isn't lighting.
Now, it is connected with a 12V, a remote and a reliable ground. The same connection worked with my alpine PDX 1.600 so it is not the problem. The sub I use is a Pioneer 1000W (I don't remember the model), but it works with my other amp, so I assume it is not blown.
I opened the amp to see if there was any sign of burning or exploded capacitor, but it look like new. The fuses are still intact.
I really have no idea of what could be the problem or how to resolve it.
yup, cooked the finals probably. Orion also used to hve a bad habit of sanding off all of the IC silkscreening so you can't replace the transistors etc due to lack of part #s.
