Primare i21 broken, no sound

gimpi · 26th May 2011, 06:16 PM

Hey, have a Primare I21 is no longer functional. The lights in the front and all of the buttons works, but there is no sound to speakers. What happened was that one speaker cable short-circuited amplifier, wondering why on where the error most likely is. Attach a picture of the motherboard. Thank you

gimpi. What you could do is measure some voltages in the power supply. If "the front and all of the buttons works", it should be possible to check the power supply with the main amp board out of the chasses. This is not always true, but often. Do you have a volt/ohm meter?

thanks for your feedback, do not think there is something wrong with the power source. amp lights in front and it lights up the screen. Short circuit on the amplifier by the speaker cable, the + and - come together. yes I have a multimeter and have tried a bit of troubleshooting, but hard when I do not know where the error might be.
