No

 

[Perry Babin]

Do you have a square wave on 2 terminals of Q12 and Q13?

 

[caraudioguy2100]

Yes

 

[Perry Babin]

What's the DC voltage on pin 14 of U4?

 

[caraudioguy2100]

3.35

 

[Perry Babin]

Lift pin 14 of that IC.

 

[caraudioguy2100]

Ok lifted pin 14 of U4 still no change

 

[Perry Babin]

What's the DC voltage on the pad that pin 14 was soldered down to?

 

[caraudioguy2100]

3.35

 

[Perry Babin]

DC voltage on pin 18 of the 3526?

 

[caraudioguy2100]

4.98

 

[Perry Babin]

Are you sure that pin 14 is actually desoldered?

 

[caraudioguy2100]

Yes

 

[Perry Babin]

On the two LM5110 driver ICs, confirm that you have the same voltage as in U4-14.

If you do, desolder pin 8. Do this one at a time to see if one of the driver ICs is pulling the voltage down.
