Replacing and configuring a main power board to a Plasma display is not a simple job as you thinks. With only a multimeter, you can't do anything. It is a skilled work. Contact any experienced service technician. If you wish to get more details about the repair process of plasma displays, check this link. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.
