Common faults
| Fault | What we check |
|---|---|
| Won't turn on / no power | Power supply, battery protection or charging circuit fault. We test the battery and the board before quoting. |
| Active speakers lose their link | Inter-speaker connection, Wi-Fi module or firmware fault. We test both speakers together. |
| No picture or sound through HDMI | HDMI board, HDMI switch chip or firmware fault. We test every input and output with our own sources. |
| Amplifier or receiver goes into protect mode | Shorted output stage, failed power-supply rail or overheating. We trace the fault on the bench before replacing anything. |
| Rattle, buzz or a blown driver | Damaged cone, voice coil or crossover. We check whether the driver or the amplifier is the cause. |
| Dead after a power cut or surge | Fuse, power-supply or standby circuit damage. Often repairable at component level. |
