Ok, so I took off the top board to see what was up with the lower board.

This is the top board channel A (which I believe to be OK).



Underneath we have board for chB.



Fobar.



It looks like the whole thing overheated! The thermostat is only hooked up to the heat sink of channel A.



So I guess the moral of the story is, do not get the home theater version with thermostat.

What would you guys do? I'm absolutely going to disable that thermostat if I get to buy a new board. I can never imagine they replace it at no cost, lol.

That's not a thermostat problem. Something shorted. Contact Johnson. Looks like the fuses might have popped, cracked, then arced to the board.

You're probably right. I've removed the board to inspect further. There are two obvious places where it has been damaged.

and here



Rare side of the board seems scratched up etc.





I have contacted Mr Johnson @ Sanway for aid. To me it seems to have been compromised from the get go (all the scratches and rails on board has been compromised). It seems to me like I need to buy a new board. Hopefully it'll run smoothly.

I agree, the amp would typically shutdown well before there is any permanent damage.

Hopefully, you can get it sorted out through a quick board swap.

Yes, hopefully it's not something else that made it pop. Got my hopes up seeing all the scratches on the faulty board. If all fails I'll have to fork out for a new one, :,(

My 10000Q gave up the ghost in rather spectacular fashion at my show yesterday. I smelled something funny coming from the area of the amp rack but couldn't isolate it. About an hour later I heard a few loud pops and looked over at the amp rack and saw smoke and flames inside the 10000Q. All my amps were bought a year ago almost to date. See pics below.

Just wanted to update the forum. I have a email in to Johnson and will follow up with how he handles it.

Sanway and Mr Johnson is determined to help me, and they will send me a new board at their expense because the amplifier is so new. We're now in the process of checking if the other board is ok.

So Sanway is keen to keep their customers happy, which is great news for everyone who contemplates a clone. Knowing I'm in good hands: As soon as this issue has been resolved I will order a FP10000Q for my 4 midbass modules.

That, to me, sounds like a "warranty" from Sanway.

Hummm...

We need to find out how long this "warranty period" is....

I tried to talk Sanway (Johnson) into letting me ship them one of my old broken amps for them to replace it with a new one... I was even willing to cover the shipping and throw in $300 for the trade in...

It sounded logical to me...Johnson, on the other hand, didn't entertain it for a second. Like he forgot how to speak english that day...lol.

Hehe, I have asked him many questions and he has always been very polite and helpful. They sent me FP10000Q when I ordered the first FP14k, and I did him a favor that time by offering to sell it for him here locally, or ship it to his next customer so as to avoid excessive shipping cost for them. He ended up sending me a FP14k, then I held onto the FP10000Q and shipped it to his next customer at his request, then he paid me back shipping expenses. He was very great full that I helped him out on that one, so it might be an influence in his decision here?

Or maybe they realize that they will win big on keeping customers happy?
