Instrument gauges not lighting up. Can anyone help me trouble shoot?
 

I'm trying to trouble shoot my 95 ls 400 instrument gauges because the lights have went out and I have a new instrument panel put in it. Is was working fine for a couple of weeks.

First of all, the troubleshoot needs to distinguish which side is causing the problem. The side I mean is the diver side or the driven side of the back light which is a CCFL. Are you ready to distinguish those using some equipments (an oscilloscope and a high voltage prove and an ESR meter) and the skill? I'll give you some more ideas to troubleshoot if you are ready.
