If you switch your meter to ohms, what is the resistance across it?
Also, if your fingers were bridged across the probes, that could skew the readings (but not likely as much as shown).
Is R202 within tolerance?

I just measured the capacitor in ohms scale, and give me: 15, 18, 20 megohms, does that mean it's okay?
My fingers were touching the probes, yes, but it was just to make the picture above gave me the same measure, without touching with fingers ...
Yes, R202 is correct. (22ohmios)

The capacitor needs to be replaced but if the resistance value started low and continued to increase, it wasn't likely to cause your problem.
Can you easily remove the other driver board and move it to the other channel?

Okay, I get it, thanks for the info.
Yes, Perry, I think it will be easy to remove, now it's too late for me, I'll do it one of these days that I have free, before it gets to me the other amplifier.
Soon.

Well, I got the driver card that was really the card I am repairing, and before installing it on the side of the latter that I mentioned, I thought, I'll connect the amplifier to see what happens with channels front, and indeed work perfectly.
Then, I installed the card in the place which was the defective card, I installed the mosfet I removed earlier, and connect the amplifier, that channel works perfectly.
So I just need to recheck all the pieces, and finish installing the components that I need, in the defective card ...

Well, I've rechecked all the pieces of the defective driver card, and I have not found defective, nothing more.
I managed to get myself an electrolytic capacitor, to replace the defective (also rechecked him and gave 0.5 microfarads, and its impedance was fixed or falling) I replaced, I installed the card on the motherboard, and when I connected the amp, great! all channels work!
Another achievement more!
I had to clean up a bit, the aluminum chassis, because it had excess aqueous liquid resulting from the thermal paste, (note photo) this ... could it be due to a fault?
Well, anyway, I'm happy because I already repaired, give much thanks, Perry and Seankane, especially because Perry is a genius and helps me whenever he can.
I'll leave a donation to this forum.
