Eclipse DA6213 repair

DcMaN · 24th January 2012, 08:43 PM

hello, im currently having some issues with an Eclipse DA6213. I was hoping some one could help me trouble shoot it. The amp powers on, but the green light does not come on and does not produce any audio output. Ive checked on the board and everything appears to be in tact and in good standing. Fets look good, nothing looks out of the ordinary. Any help is appreciated.

Thanks

-Rob

I shorted out a power supply fet by mistake last night. But even prior to that the green light never came on and had no audio output. You can see it , the second one in on the top right hand side.

Ive checked the voltage on the rails by the power / ground terminals, all is well there, however when i check the rails for voltage by the power supply fets, i dont get any reading

Do you read 0, 12 and 0v on the legs of all of the power supply FETs?

Have you checked the output transistors to see if any are shorted?

i checked the fets and they did read 0-12-0v on all untill i shorted one out. Whats the easiest way to check the output transistors ?

this amp uses NEC K3057 . I wasnt able to find these anywhere. Is there a good substitute to use ?
