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?
