You problem represents a defective Y-sustain board and or X-systain, The most common failue among plasmas is the y-sustain board. If you open the back you will find the Y-sus to the right and the X-sys to the left. Unplug the power connector to the y-sys and see if the unit stays on, during the POST or Power On Self Test you should hear the power supply relay click on then moments later the system power on relay if the power supply is ok. There are two things to look for in plasma failue Y-sus and Power supply failue. If you push the power on button and nothing happends no clicks from PS relay then you may have a Main system control borad failure.

This is a power board issue. Check that there are blown caps in the power board and replace them with the exact parts.

The tv is not coming on. At first the green light comes on then the light turns red.

Check the inputs on your TV, are they correctly inserted? Is there a device connected to them? Try to change the input on your tv.
If this problem persists, it is your power supply failing, and your tv needs maintenance.
