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

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 
jny,

Just Google Jeff Rowland contact number. I sent you a pm with the number and verified it was correct. You will need an authorization number to return any component for repair. They are very responsive and usually provide outstanding customer service.
