Question about Sony BRAVIA KDL-52W3000 52 in. LCD Television

1 Answer

No display on TV when an input with signal is selected.

I have a SONY-KDL-52W3000 that i recently got from a friend of mine. It was working fine until one day the display on the TV wouldn't work unless you switch to an input that had no signal. WHen you are on any input with signal the entire TV display disappears and all that you have is the back light. I'm not sure what is going on with it. I opened it up and from general knowledge everything looks fine. Any idea for a cause?

Try a new or known to be good cable.
Try attaching to a different computer.
Prove the monitor will work first.

    I haven't changed a thing, It's been plugged into the same coaxial cable and had TV on it a week ago.

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).

SOURCE: Hello My, just bought Sony KDL

I have one of these. It is probably set up for some other program like the HDMI or Input 1 through 5.
You can press your INPUT button, then scroll to the TV function, which should show up on the top.

I have a different Sony, but I think they all work the same. Go to menus (Press Home) Then select "Settings" and select "Screen Settings". Set Wide Mode to "full", Auto Wide to "off" , Auto Display Area to "off", Display Area to "normal". I hope this works for you

I have a Sony model KDL-32BXR6 that the TV Guide first showed no listings this past weekend. Last night when I entered the Guide the screen displaying the Setup/Display Setup Progress came up stating "In Progress". Same thing this morning. Something must have changes with the input signal if this occurred with two different sets.

I have a sony Bravia KDL-52W3000 LCD tv. Approx.


I have the same tv with the same problem. My tv is about 3 1/2 years old. I took it to the shop yesterday and today they told me that I had a bad lcd panel and a bad FL1 circuit board. They also told me it was going to be $3800.00 dollars to fix. I am now on my way to buy another tv, needless to say it will not be a Sony. Sony knows about this problem and refuse to do anything about it. Good luck.

Coaxial to component


You may need an extra HD tuner for your TV. The only problem that you may have would be the original signal running through the coaxial cable. If it's just regular TV stations, the tuner should fix the problem.
