Question about Sony KDL55EX640 55" LED 1080p 120Hz Wi-Fi ready HDTV

1 Answer

My sony bravia kdl55ex640 left side of the screen is dark. I can still see the picture but it is much darker than the right side. It is an LED t.v. and is 18 months old. I used to be able to fix it by giving a light tap on the back of the set but now, nothing will fix it.

This is a back-light inverter problem.

Testimonial: "Thank you for identifying the problem but I would like to think that Sony will bend the rules a little on the one year guarantee as it is just the one year and I imagine the repair required might be expensive as the TV was to start with. I will ring Sony and test their public relations and discretion. Have a good day."

Hi Brandon,

Why is sony bravia dark screen


If your TV seems to be darker than you think it should be, it is possible that the problem is with the light sensor. The light sensor will automatically adjust the picture brightness based on the ambient light that is in the room, (i.e. if the room is bright the picture will also be bright, if it is dark the picture will also be dark).

To turn this feature off go to Settings > General Setup > Light Sensor.

Sony 52 inch bravia picture went dark


Hate to give you some bad news...But most likely you have a defective screen. You may be lucky and just have a bad T-con board. Which will do the same thing. But, this is a slim chance of it being the issue. As I have had many of these with bad screens. And only 2 were the T-con board which the color was off and pict was darker than normal. It is the board at the top center of the TV.

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.

I have 2 sony bravia with freezed dark vertical lines across it making that potion darker in color


If problem is one side or one half of the picture this LCD may have an inverter issue--Google the model number with either "inverter" or Parts to see if the issue is known.

Lines that are black usually are either a "handshake" issue where boards are not communicating properly or a bad board or even a bad display unit (main screen Panel) which is fatal.

This requires testing and or replacing boards to see if a board or the Display panel is causing this issue.
