Rockford Fosgate R600x5 Ver 1.2

[cajones65]

Hi am looking for help with this RF Prime R600x5. I have power and no sound. I have rail voltage -41.34 and +41.47. I have a 37.5 kHz signal on power supply FETs. Not sure if I just have a muting problem or what.

Was that burned area under the remote jumper part of this repair?

 

[cajones65]

Its referenced as C10 from hot to grd.

 

[Perry Babin]

Are you saying that the capacitor burned and burned the remote trace?

 

[cajones65]

That is what it done, yes sir

 

[Perry Babin]

Do the driver boards plug in?

Do you have a right-angle probe to get readings from the two LM339s on the driver board?

 

[cajones65]

The only board that plugs in is the RCA board. The other 2 boards are soldered in. The power supply (pwm) board has a LM358 I don't see a LM339, and there is only one.

 

[cajones65]

The other 3 ic's on the board are 74hc4060d, CD4018bm and 494

 

[cajones65]

On bottom of the (solder side)board there is 2 393's, and a tl072c.

 

[cajones65]

Oh by the way I do have a right angle probe.

 

[Perry Babin]

OK. This configuration is completely alien to me. Maybe someone else will be able to help.
