Kenwood BB5 Hello All, I have a Kenwood BB5. Power on and the relays click, click click. its the 3 relays on the left of the board. i tried to isolate the relays by removing them off one by one and found that all three of them do it. which led me to think its the control circuit for the relays and not the relays themselves. i also directly connected the points but the power amp wont come on. the rest of the systems come on. could you please help. THanks a million.

Issue with Back light LED

Hello Jason, from what you are saying, it would seem that the problem is inside the Subwoofer speaker, I do not think it originates in the Kenwood
Before you try changing the RCA-RCA cable between the Kenwood SubWoofer output and the Subwoofer speaker input
Also control the power cable of the subwoofer, if it is with an interlook, replace it
You have not commented that Sub you have, tell me the brand and model
If with these tests, you do not have positive results, take the Sub, to a specialized technical service
I hope you can solve this issue
Greetings Franco Dosil

Hola Jason, por lo que comentas, parecer?a que el problema esta dentro del bafle Subwoofer, no creo que se origine en el Kenwood
Antes prueba cambiar el cable RCA-RCA entre la salida de SubWoofer del Kenwood y la entrada del bafle Subwoofer
Tambi?n controla el cable de alimentaci?n del subwoofer, si es con un interlook, reemplazalo
No has comentado que Sub tienes, dime la marca y modelo
Si con esas pruebas, no tienes resultados positivos, lleva el Sub, a un servicio t?cnico especializado
Espero que logres resolver este tema

Pull the back off and see if you can see some bulged capacitors if your comfortable doing this, another issue could be bad solder joints on one of the boards, you could try baking each board starting with the power supply board in the oven to see if this corrects it, there are vids on youtube that tell how to bake the boards.

The thing that clicks is a relay. They can and do stop working. However, the cause might be a fault in the power supply or in the main output causing an overload so the thing won't click.

bad circuit board

Try it without the speakers connected before doing all that surgery.

Hi,

Your TV must have bad capacitors on the power supply board.
The tops of the capacitors will be domed/swollen.
Replacing the capacitors will fix the problem

when you take the back off, locate the plug wires from where they come into the back of the TV follow them up and it will end in the control board. search for the capacitor that would have bulged or swelled. This was not just take a quick look, it would be so slight that it wasn't even really apparent until we scrutinized each one.

Replacing this Capacitor would solve your problem

Please leave me comment, if you need further assistance

Hello debrahood196,

You first need to determine what is causing the "no sound" problem. (1) Try the sub(s) on a different amp (a friends maybe, or a local audio shop) and make sure that it/they work properly. (2) Test the outputs from the receiver. (3) Try a different pair of RCA cables. (4) Check the speaker wiring. (5) Check your head unit settings. (6) Check the amp gain. Once you have isolated it, repair or replace the defective wiring or part.

Hope this helps.
