SOLVED Kentauride No Sound

[joelorigo]

I have an Effects Layouts Kentauride that I have finished but there is so sound in either bypass or effects. This is the first time I've had this specific issue; could someone tell me what is the first thing to do? (Photos included)

Bellow are links to the project and the build doc.

Also, I got the audio probe out and I am still not getting anything at R1. Getting signal at the IN pad. Since that is the first component in the schematic, there should be signal at R1, correct?

Yes, but only one side, but both sides of R2. Check the continuity between the in pad and R1, if you have continuity, you should be getting a signal, there’s nothing between the two.

I am not getting continuity between IN and either side of R1

EDIT: I am getting continuity from the IN sleeve and both sides of R1

This can happen if there is too much flux on the Pads .
The probe may not be getting contact at the IN pad???
You should be getting it from the IN tip, not sleeve???

 

[joelorigo]

Just to clarify, I am getting continuity between the input jack tip and the IN T pad on the PCB. I am not getting continuity between either the IN jack tip and R1, or the IN T pad on the PCB and R1

I am getting continuity from the IN S pad and both sides of R1, so that's ground on both sides of R1. And that's not good, right?

EDIT: Yeah, both side of R1 have continuity with the DC jack negative / gorund.

Jumper from PCB IN Pad to R1, It runs along the edge & may have been damaged:

 

[music6000]

Your doing this Continuity test with Power plugged ON or Off, I has to be with No Power plugged in!

 

[joelorigo]

Oh shoot I think it was still plugged in from when I was using the audio probe! Sorry!

 

[joelorigo]

Tested continuity UNPLUGGED

Same results as post #64

To be clear, I have been testing from the IN T & S pads at the top of the PCB.
What are you saying might have been damaged?

 

[joelorigo]

I am getting continuity between both sides of R1 and that lower pad labeled “1”

 

[music6000]

Are you getting Continuity on IN T pad & IN S pad at the top of PCB?

 

[joelorigo]

Not those 2 pads, no

 

[music6000]

See this doesn't make sense, R1 -1M is the first resistor from the IN pad at ''1''.
The other end of R1 is Ground which is also the Sleeve/Ground!???
Have you checked for solder bridges under the Footswitch Breakout Board???

 

[joelorigo]

Ok this is weird. I got an email that there’s a new reply to this thread but I don’t see it here.

Copying from the email it said:

pretty much has to be one of these things

1. bad solder joint on IN pad
2. IN pad is messed up and not connected to trace (did you ever apply a LOT of heat to it, unsolder something from it, etc?)
3. broken trace somewhere between IN and R1
4. bad solder joint on R1
5. R1 pad is messed up and not connected to trace (did you ever apply a LOT of heat to it, unsolder something from it, etc

I will answer here:
For #1, the IN pad has continuity with the tip of the input jack so that seems ok, no?
For #2, I don’t think I applied too much heat and did not unsolder anything from it.
For #5, same, I don’t think I applied too much heat and did not unsolder anything from it.

I have removed that footswitch, because that seemed to be the culprit with not getting any signal in bypass. Now I have a new switch wired without a break out board

It was but must have been deleted by the Member???

are you getting Continuity to both sides of R1 & IN Sleeve & also Ground?, No Power connected!

 

[joelorigo]

Yes, that is what I’m getting; continuity between IN S and both sides of R1, and between the ground (-) on the DC jack and both sides of R1.

 

[music6000]

You have a Short somewhere
Can you tell me which Number pin on the Footswitch is IN T going to?

 

[joelorigo]

I don’t know. This how it is wired though
