Hi all. My computer speakers have stopped working. Grandlab M-333. It's a cheap, little subwoofer with an amp inside and 2 satellite speakers. They sound great and I'd like to learn more about repair. l've replaced the (3) burned TDA2030A's, (2) 3300uf 25V caps, and I now think there's no output from the transformer. I should see 13v between each blue wire and the black (outputs), true? I've got 120v AC in and 0 AC out. The power switch seems to have fried "ON", by the way.
If so, can you guys help me find this transformer or a suitable replacement? I've had no luck. The numbers on it are SY-57A13110D02. I/P 120V~60Hz. O/P 13VX2~1.1A.
Thanks! And if you can recommend anything else to replace or check I'd much appreciate it. I assume that the transformer failed and took out the other stuff. ? It has a strong "burned electronics" smell inside. I've attached a few photos.
