I would not leave that stryofoam in there, it could present a fire
hazard.

Wasn't planning to, just a temp fix till i get appropriate feedback
and find a solution, Thanks anyway Mr. Darby :)

I can see three approaches.

The first is a brute force approach. It depends on sufficient space
between the perforated shield and the back of the TV. Judging by the
styrofoam experiment, a rectangular 'can' of that depth could be
constructed and the back shield modified so there is additional
clearance between the transformers and the (extended) shield.

The second is more elegant and more work to achieve. Inverter
controller ICs monitor a number of parameters, including output
voltage, CCFL current, and even drive current. Determine which
parameter is causing the shutdown. Then analyse the circuit to
determine if the setting is overly conservative, components have
drifted, or a component (driver?) is marginal for this application.
The solution might be as simple as changing one resistor, or as
complex as redesigning the driver circuitry.

The third is simple - check with Hitachi and determine if there is any
modification kit to resolve this problem. I don't hold a lot of hope
that there is, but ...
