My dav-340k was working perfectly then after sometimes it lost sound output,even with the full volume no sound at all n no any warning n nor indication. what could be the problem?
SOURCE: why does push power protector keeps flashing in
This is an error massage and comes when home theater got some internal problem specially in amplifier output section that can have defective output IC etc.
It is not user level repair and requires qualified tech for fix.
Thanks.
SOURCE: "Push Power'' and ''Protector"
your sound output IC is short circuit and needs replacement.
Caused by :
- Heat playing full blast for long
- speaker wires schorted
- or bigger or more speakers was aplied
THank you
SOURCE: IT DISPLAYS PROTECTOR PUSH POWER
its in standby, try it again, if it does it repeatedly theres a problem in the switching power supply not letting it power-up to save components

SOURCE: appears PROTECTOR, push power button,
Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.
