Hi everyone,
I just got a Logitech X-540 amplifier which does not work right. It is a 110V amplifier which was in a 220V-to-110V power converter while there was a power fluctuation (this is my explanation).
Symptoms: when turned on it is silent for like 2-4 seconds and then an intermittent low-frequency high-volume sound starts buzzing in all the speakers.
I opened it and i saw a pumped-up capacitor (the one in the power supply stabilizer, after the transformer, it is a 25V 6800uF capacitor) and also a resistor (a really heavy one) but the resistor is so fried out that you can`t see any colors, only the blown coil.
Please, can anyone help me with this?
I will also upload a few pictures of the amplifier board.
Thank you very much, I really appreciate
