Even changing a parameter which results in the loss of the picture could
require replacing the EEPROM if you cannot get the set to come on and view
the service menu to reset!
However, it may be possible to drive the HOT with an external source
so you can see the menus for setup.
CAUTION: there is some risk. Should drive the HOT with too low a frequency,
it may blow due to flyback core saturation. Use a series light bulb to
minimize this possibility.
