The unit was purchased damaged as a "project" unit. No warranty information
was included. I'd like to be able to diagnose and fix the problem myself
before I give it to a repair shop and pay $$$ for what looks like an easy
fix. Any pointers on how to diagnose the inverter card/LCD greatly
appreciated..
Thanks,
Adam
