Try pressing the TV/Video button. The problem could be that the TV is set to an input with no source.

It is not designed to be changed over. Even if it was, it would probably cost more to do it than what it would be worth.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
Remember there are leathl Voltages inside TV's, and generally these days don't contain any "User Servicable parts" like in the "Old" days, instead Board Replacment is all that is generally done.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

You either have failed 24vdc power supply section or failed backlight inverter board, check for 24vdc first, look for caps with leaking/bulging top.

I have a sony KDL 46xBR2 when I turn on powers up green light stays on but a dark gray screen no picture or sound


The green light merely indicates that power is getting to your TV. The symptoms you describe point to internal power supply failure

When you push the power button on the TV, the green power light will come on but the back light won't light up and the picture won't come up. I tried to contact Sony and all they could tell me was to take...


Yes it is best to bring it in the nearest service center. just to clear it for you, your TV has problem with the power inverter. If your TV stays On and you can hear the audio but your screen is dead set black.
If yes, your problem is with the ballast or inverter this gives the luminous light on the screen in each side for you to see the clarity of the picture. try to replace this defective inverter or have it repair. this is the same remedy the technician in the service center will do.
well hope this helps, please rate and vote.
