Hello! I have AV-reciever Pioneer VSX-LX302, and see on the display "NG:L / Det. Protect I" after some experiments with loudspeackers ). Any knobs don't work. I check output transistors with diod test - seem that it's okey. How can I reset protection? I tray some combination (for ex, Enter + Power On), but nothing change. I want to change output ttansisoirs in left chanel anyway - may be somebody has a service manual for this model?

I'm not familiar with Pioneer, but Onkyo has the same error code, when something goes bad. That indicates, that is something wrong, at channel "Left". It could also be bad components, at the preamp section. I would test all the components, at that channel.

Thank's! But the overload was in the output section (I think, short connection in the left and right main chanel). I disconnect preamp section of this channels, but the error exist anyway. But the outputs transistors is ok (due to diod test). I plane to disconnect this transistors from the board and use the power amp, connected to the pre-outs for stereo chanels. It will be ok?
