1 Answer

One half of screen sees darker than other

I have just got my Sony Bravia 32 ins LCD TV back from storage.I have managed to tune in all alloted stations (running on analogue signal as unable to receive digital signal in area).
I am receiving a pretty good picture but top half of screen seems darker than the other.This is particularly noticeable when switching on teletext (screen text) or putting on a dvd on allotted dvd channel.
I have tried adjusting backlight,contrast,brightness,colour,colour temperature,sharpness etc but nothing seems to work.Are there any hints,tips or ideas that may help me.

Sony bravia kdl-40s2010 top half of screen is fading

Most sets use two boards (each drives the image on half the screen) some combine both into a single larger board but if a even half of the screen is doing something the other half is not that is where the problem likely is.

Different makers use different names for this like T-Con or Y out etc.

You if interested might Google the model number with "parts" which may provide you a list of the boards in this set along with prices in some cases.

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.

The top half of my Sony Bravia 32" screen plays as

I'm sorry, it sounds problem with lcd panel (screen) that is defective and causing lower half distorted image. If tv is under warranty then call number written on warranty documents for warranty cover or lcd panel (screen) replacement would cost you approx 80% of new tv price.
Hope these info will help you.

Upper half of screen is darker than the lower half

Its back light in LCD Panel problem, there are approx 20 CCFLs in 40" lcd panel and one or two in upper half is not providing enough light to give proper brightness so you see bit darker image.
As per Sony policy, lcd panel will be replaced to fix this issue and local tech can fix it on component level (replacing bad ccfl) if he/she agrees because its risky work.
Hope this nfo will help you.

Sony Bravia LCD half screen is darker shade sometimes

Magnetic fields don't affect lcd screens, unlike crt tvs where a magnet can cause problems. If it is only a slight difference i have seen this before even on my tv. if you go to a blank screen you can see patches of light and dark, they call this bruising, i have talked to sony engineers about this but i have not got a straight answer as to what makes this happen, if the tv is in warranty a tech will replace the panel, if it is not in warranty it is not cost effective to replace. But the good news is that is does not seem to get any worse with time, it is more of a manufacturing defect that most will not notice. Look at the tv with dark blank screen and you may see areas where the screen is lighter than the other. If you see this than you have this issue. it will fade off and will not be a stark line. Also I noticed that there is a software update for your television go to to get a download of the software, or sony will send it to you free of charge.

I have a sony bravia xbr 32 inch and the picture is only on half the screen

It is possible that Twin Picture function is enabled, turn it off with remote/ menu options.
If this is not the case then T-Con board sounds bad and needs to be tested/ replaced.
Qualified tv tech will test and replace it.
