Hitatchi problem, put in new power supply. Attatched a pic

I have posted the problem with my Hitatchi big screen.. I now have put
in a new power supply. I hooked it up and it would shut down upon
turning the tv on.. I was trouble shooting and found that if I
disconnected the two connectors pictured the tv will come on and stay
on. It has sound but no pic obviously. There are 3 connectors that
go to the board board beside the power board that controls the color
tubes. When I push these connectors in the power board will shut off..
Any ideas what to check for. Another question.. To remove the board I
have to unhook the 4 wires that power the color tubes. These are
plugged into the transformer. Do I just unplug these or are there
precautions to take before unplugging them?

Is this the set that got spiked by lightning? If so it's going to be a
tough dog for an experienced tech to trouble shoot let alone someone with
limited resources. I understand your frustration but you can only expect
so much real help from a news group.
