Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.

Red light goes on and off


Needs the button put back into place. Look under the cabinet to see if there is an access panel below the switch, would go for all external controls. There would be a chassis with all the controls mounted to it.
Pull the plug before doing any repairs.
Look to see what it would look like in it's normal position. Something has moved out of place that holds the switch to the panel. Very tedious if you have to remove the whole housing.

Tv will not turn on i push power on button and blue lights click on an tv acts like it will come on but then tv shuts off and no picture appears


The blue light merely indicates power is getting to the TV. When you press the power on button, the defective power supply shuts the TV down immediately
