Hi, assuming you can open the enclosure of the Advent, work on the amp section (please make sure you've isolated the power supply and you will be working with the low voltage section of the circuitry only.) Inject an audio signal, it does not matter where in the amp section, just try the different solder points of the small capacitors normally in the 1uf value. at least one of them should give you a good amplified output from the speakers. In the absence of a signal gen, you may want to try (with care)using your bare finger which should produce a humming sound of about 60HZ or a slight thump in the speaker. If such a sound is produced, then the amp is good and the powersupply is doing its work. You have now isolated the problem to the 900MHz receiver. Am not sure if you can purchase modular replacement in your area but you can also try the sig gen or finger method except for the front end (rf section). Re the humming sound, such a problem is normally related with the power supply section with a defective or leaky capacitor. It is also possible that the input stage of your amp is not grounded right. You actually have just to work on it in stages to simplify fault diagnosis. Since you can hard wire, why not try salvaging parts/module from one unit and putting it in the other to make at least one working while looking for replacement parts/module for the other half of the Advent. Hopes this work out for you. Please let me know how things turn up. Regards

Double check your connections at the transmitter. Swap inputs to see if the popping moves to the other speaker. Popping usually means blown, however......
