How long does an inverter card on a TP usually last? I'm trying to plan ahead to reduce future downtime, and would like one on hand as is necessary. Thanks.

Also, to test if it's the inverter or CCFL, I assume you could use a DMM to test the voltage output from the inverter. What voltage (or voltage range) should the inverter be outputting if operating correctly?

LCD inverters normally last the life of the display. Of course YMMV.

Since I believe the output is dependent on a load, the only way I know of to accurately test an inverter would be to plug it in a known-good spare backlight. Scott.
