Does this mean my amp is blown?

My amp stopped working so I figured it must be blown and since there's no remaining warranty, I'm starting to tear it apart. Does this white stuff come out of those campsules to put out a short? Or is it just non-conductable stuff to glue that stuff to the boards?

You have any before pics?? lol

I have never seen any of that stuff on my amp or my friends. A buddy of mine blew his but I didnt see any of that, he just had a small capacitor missing and a black spot where it was with the wires still sticking up.

It looks like those capacitors are busted. You might be able to replace them If you have any soldering skills, but there could be something else wrong also. It might be better to just get a new one or send to somebody to let them repair it.

Nah I don't have any before pics. That's why I'm so confused... I can't find any black burnt areas =\

It looks like it was put there not leaked. My guess is they noticed some defects with caps coming off the board and started gluing them to prevent vibration from breaking the contacts.

The way that stuff runs over and covers other transistors and things just dosen't look right.

That looks like heat sink compound although im not sure why it woud be there. Get the values of those caps and unsolder them from the board. clean that crap off of there and solder some new caps in and give it a try

That "stuff" looks like it was squirted in there on purpose, so that's probably not it. How or when did the amp blow? Mono or multi channel? Brand? Protection or over-heating light on?

That grease needs to be there. The transistor has to transfer the heat created but stay isolated from the sink. The power supply transistors are on the left and the output transistors are on the right. It looks like a poor design with multiple amps made from that board judging by the amount of jumpers used. It's low power judging from the size of the power supply and the resistors and caps are low grade. If you don't see an open trace or resistor I would call it an extremely effective paperweight.

that white stuf comes from factory, in the picture all the capacitor looks fine if they were damaged thay would have blow out but in an amp is really dificult that it hapens, i am really shure that the problem is with the transistor check them with a multimeter or tell someone else; when an amp gets damaged usually is because of that maybe a bad wiring or an accidental short c. any way let the caps just were ther are and put an eye to the trans.
