Sony KDL-52XBR3 has stopped working

My 8 year old Sony LCD TV KDL-52XBR3 has suddenly quit on me. When I switched on the power, the green button light fades away within several seconds with no picture and sound. Any idea what's wrong? Thank you all for your assistance.

This looks like a 2007 model.

While not quite 10 years old I don't see a lot of posts in TV repair forums. gives us a clue that repair may be more than replacement.

But give it the old try of unplugging it from the wall and remove all cables then wait a hour to let it reset what it can. Apply the mains only and see if it powers up.

To go deeper

You have to get a service manual and follow it's diagnostic tree. You may need gear like DVMs and Oscilloscopes. Many home repair folk take big chances and just buy what may be failing. That is "guessing."

Let me be clear on 2 things.

1. Opening the set up is not for everyone. There are lethal voltages exposed and no one today will tell you to open the set. It's your decision and you can't sue because no one will tell you to open it up.

2. The symptom is not telling us what part inside to replace. It only tells us it needs repair.
