Notification LEDs not working after WWAN antenna upgrade

[jazzaddict]

Greetings,

I have just installed WWAN antenna into my x61, now none of the notification LEDs (on LCD inverter) are lighting up except for the WIFI's. I've checked all the cabling several times and all the jacks are plugged in firmly but I could not identify the problem. I would appreciate any expert advise on this. Thanks!

It's going to be a bad or unseated LCD cable either at the systemboard or inverter, or the inverter itself.

i checked all the LCD cables at both the system board and inverter. Must be bad cables... [censored]!
