Sounds like the upper backlight tube is out.
Unfortunately, you cannot replace the backlights individually, you must replace the LCD panel, which includes the power supply. The KDL-40S2000 LCD panel part number is 1-802-059-22. It costs 805 USD at http://servicesales.sel.sony.com/ecom/accessories/web/productSearch.do, but they won't ship outside the US.

SOURCE: Upper half of screen is darker than the lower half

Hi,
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.

what you can do is to remove the back cover to access the inverter board. probably the cause of the smell is burned inverter board for the screen back light ( ccfl ) at the upper portion of the display.you can find the inverter board near the power supply board. usually you will replaced the inverter board since most of the part get fried as will as the pcb pattern circuit board get burnt.hope this can help good luck.

It sounds like your black (K) or Black/Yellow (KY) head needs to be replaced.
The problem appears to be in the top half of the black head.
Without knowing more (like what make/model the printer is) I can't help more than that.

Upper half of the monitor is darker


I would try an auto-adjust first see if that helps any, also you could try it on another PC to make sure its not your video card on your PC. Another option is to reset the screen to its factory defaults see if that does anything.

Screen split in half


Hello, same thing happened to my 10 day old 60ps60 and we called LG and they came out and put "pin tighteners" on the Y board. All they are are these little white plastic clips that the technician put on the connectors. It is nothing you can fix. Call LG

SyncMaster 932B blinks, then screen goes black


Check all the connections and if they are all right and tight then the monitor is probably shot. The good news is that it can be repaired. It's usually around $50.00 to $80.00 to fix. Good luck!

Screen Half darker


It sounds like your backlight isn't working properly. LCD screens have backlights that illuminate the colors produced upon their surfaces, so that you can easily see the screen without an external light source. In your case, it sounds like your backlights either aren't cailbrated, are damaged, or were produced unevenly.

There is most likely not a fix for this, though most all LCD screens have some form of light distortion. My own LCD screen is slightly brighter around the edges, where the backlights are located, but this is only noticeable when displaying a completely black screen.
