When I plug it in the red remote stand-by light comes on when I push the power button on the remote the red light blinks then goes off but there is no picture or sound?

How many red and green blinks to you see? (What pattern?)

Try pushing the source button on your remote after the red light stops flashing, Keep pushing the source button until it is on "TV". You may have set the remote to one of the aux settings by accident. My dogs do it to me all the time. Good luck.

check the psu, if you can manually switch the power the power then its going to ease your work

Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

This happens because the power source has failed. What has caused the failure can be found only by testing it - but my guess, based on how it behaves, is that the high tension for the panel is faulty: the filtering capacitors have failed and fried the rectifier.
