Macbook LVDS Bodgewire (via repair) bypass resistor?

[Vinnie]

Hi all!

Quite new to this and need some help (or point me in the right direction).

I have an LVDS connector on a Macbook that most pads are gone and I am building them up one by one. Some of the vias pass by resistors (see picture) and I was wondering if I can just solder a wire onto the probepoint (more like the ring then a closed probepoint) or should I do it from the resistor itself?

Essentially - can the resistor be bypassed or not? How does one do if you need to repair a via usually?

Thanks for the help! (And sorry if I use the wrong lingo - again, just having fun with electronics and trying to repair stuff).

Hi. Need to review each resistor and its value. If the resistor = 0 ohms then yes, it is a basic short circuit across the 2 surface mount (SMD) pads.

If the resistor is indeed 0 ohms in resistance only then you can bypass the need for the resistor as you are showing in your shared posted diagram.

Confirm each resistor using the schematic for the macbook you are servicing.

If needed or in doubt, post back and someone will post the details of the component in question.

Thanks for the quick reply!

And if it does have anything else then the 0ohm value, do I solder the bodgewire onto the resistor itself?

No. If the resistor is of a different value then there is a reason for its existence. You would want to keep that resistor in place.

Summary - if zero ohms then it is just a short circuit between the 2 small pads so a wire can be used for the bypass. Otherwise, the resistor should be replaced, if defective but with the original value as shown on the schematics.
