Jeffrowland m7 mono block amps


I still need help to turn on the amps. Both monos won't turn on after one bump sound when I pushed  power button on cold amps. I see -12,+12 volt led lights on inside amp. Fuses are all good 2out side 1 inside. So need help from anyone familiar with these amps.

Thank you, jny

Sounds like you've got DC current and the protection circuits tripped.  I'd unplug them and call Rowland.
They only taking emails. Email Said they created ticket # like 2456, 2534 that I couldn't understand. There's no place to look up the # on JR websight. Asked few times. No answer now.  I guess protection circuit too but I don't know where is it.

Thanks , jny
