I have MHC - V11, I don't know how buts its audio automatically goes off after 15 min. Further, we have to figit with the volume button to turn the audio on again ? What might be the issue ? I have already reset it.

[@melelectronics1862]

Try soldering the mother board first. Check bloated caps on the power supply of the unit.

[@LnF4530]

[@melelectronics1862]

Check the oscillator ic beside mosfet.

[@donaldbiggayan6843]

di nagawa ng electrician na pinagpatinginan, ko ano po kaya magandang amplifier match dito sa speaker nya mga boss

[@melelectronics1862]

same specs lng po gaya ng sa original speaker. Pwedeng lakihan ang circumperence but not the watts & ohms.
