Most T-CON board is at the middle top center of the screen undet a metal shileld with very small wires and connectors attached to it. Most T-CON failed after warm up due to the heat from the panel and from the power supply, since heat rises, it gets a lot of exposure to the heat.

Left side is dark and right side is good


The LCD sets use backlights and also a pair (some models combine both into one unit) of inverters- one drives left side and the other right side.

You could have a bad inverter (some versions call it T-con) or even a bad display panel(main screen unit).

In most cases this is not a do it yourself repair.

Sony Bravia 46'' picture has a slight green tint and adjusting the Hue does nothing.


hello!
that could be the t-con to main board cable's problem. first, try to tighten grounding screws.those, which connecting grounding latches of the cable.
You need to open your set. This cable is a thick shielded one with two 30 or so pins plugs. They are NOT interchangeable. In case you try to swap cable's ends. Try to move latches by hand without unplugging connectors, while TV is running. Very gently! If those moving a bit, you may see "greenge" vanishing. Tighten those screws with "phillipls" screwdriver by hand. if there is no difference, you may need to replace that cable. I'm talking about "greenish" ghosts on the picture, intermittent. If I'm wrong, it might be the main board's issue, but always start with small. Main boards are not interchangeable, factory replacement only! Cables-are.
Good luck,
Alex.

Have a 2 yr old 46" Sony LCD. No picture at start up.


It may just need time to warm up. Try starting it up and waiting around for the picture to show.

Picture freezes on Sony Bravia 46 in


this can be a weak signal check the connections on cables. also in hot weather you can get a build up of static electricity and it will need to be discharged, turn off tv at mains and cross the connector and the cables if you have a buster or other box connected to them turn off and do the same to them. use something metal but make sure there is no power to them.
