Can you tell us the model # of the set e.g. KDL-40X550.

Also can we have some pictures of the electronics inside.

What tools do you have - digital multimeter?

Also i cant tell if your saying the backlight does not light up? or does it light up? (you should see if there is any glow from the screen in a completly dark room, while the set is on)

I would suggest waiting for the t-con. If that does not fix it, then we can look at the main board or LCD panel.

Please let us know if it fixes it even if you are done repairing the TV. So we can keep track of common faults.

Yes. By which I mean, no.
However, I have heard of digital reception problem with just about any TV.
Check antenna, cables, firmware updates for TV.
