kicker wx 10000.1 schematics
 
hi friends i have a kicker wx 10000.1 i am trying to repair but need some help with the schematics or a picture at least to guide me.it has two 4.7 ohm resistor incinerated and that burned some traces underneath it i can't get the resistor location for that two but the other side has two of the same resistors labelled r86 and r85 respectively.any help will be much appreciated.

i guess this ones a rare one!!!

i'll try to get some pics so you can see the burnt out spot

ok folks here is the picture

this is all i found visibly ...so far tested all op and power supply and all seem ok

i'll be very grateful if someone could add a picture of that area so that i can retrace the circuit

I'd say this amp is too far gone to be repaired.

because ?

If the output fets have gone, then the gate driver ic is most likely dead as well, which can in some cases even propagate down the line to the pwm modulator and damage that as well.

When the input psu fets go, the pwm controller ic goes, if unlucky this could generate a sharp high voltage spike on the switching transformers secondaries, frying pretty much every semiconductor on the board. In the end there may be so many parts needing replacement that a new amp ends up beeing cheaper.

Charred boards also become conductive which greatly hampers operation.

Attached are PDFs with the component values for the main board and the small driver boards next to the outputs.
Try to clean the burnt area as good as you can and restore the connections in the area.
