First and foremost, disconnect the power cord from the mains.
Next, after having removed the back cover from the set, discharge the tubes' residual high-voltage to ground using a suitable tool.
Access to the transformer is pretty much staightforward here.
A few hardware removals and you can then get to the board and transformer..
Mark, then remove all leads that go to the unit.
INstallation is the reverse of removal.
Be sure to replace the driver device, just to be certain...accordianman
