Common 2.1 & 5.1 Assembled Amplifier Problems We Resolve

Is your custom-built or assembled home theater amplifier experiencing any of these issues?

Power Failure / Completely Dead

Amplifier fails to turn on due to blown main fuses, shorted power supply rectifiers, or transformer section failures.

Some Channels No Audio

One or more channels (front, center, surround, or sub) have zero output due to damaged output ICs, shorted transistors, or open resistors.

Subwoofer / Bass Not Good

Weak, muddy, or distorted low-frequency response caused by low-pass filter op-amp faults or subwoofer driver stage issues.

Volume Control & Potentiometer Noise

Severe crackling, scratching, or popping noise while adjusting manual volume, bass, treble, or balance knobs.

5.1 Remote & Display Kit Not Working

Front display kit freezing, IR sensor failing to receive remote signals, or volume microcontroller IC lockup.

Prologic Decoder Section Fault

5.1 channel matrix decoder board failure resulting in improper sound separation, missing center/surround channels, or audio bleed.

HDMI ARC & Dolby Decoder Fault

Optical, Coaxial, or HDMI ARC digital decoder card failing to process Dolby Digital/PCM signals, causing mute output or digital distortion.
