This can be the panel itself, and or the matrix decoder/driver boards. The cost of this type of repair can approach the cost of a new set. From your description, I am thinking it is the panel itself that has failed.

Parts for your set are from Sony only because there is no third party manufacturing for these types of parts and assemblies.

Usually, when these types of sets become defective they are usually not worth servicing. During warranty the manufactures generally give a new set to the client, or they give a re-built set which has been built up using parts and modules from other sets that came back for service and had different types of problems.

If you know a tech is is good at servicing these types of set, maybe he can find a number of scrapper set of the same model to take parts from. You just have to hope the ones he finds have the same types of fault.

My Sony tech says it's most likely a bad cable box. Try a DVD and if the DVD is fine then it's for sure your cable box. Needs to be replaced by the cable company.

Sadly, a replacement screen itself would cost more than the TV is worth.

Here are a couple of web sites selling the replacement screen:

I know it seems like a crazy price. But, TV manufactures buy a mass quantity at a lower price. Where buying just one screen panel cost an arm and a leg. Buying a new TV is the best choice money wise.

It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
Remember there are leathl Voltages inside TV's, and generally these days don't contain any "User Servicable parts" like in the "Old" days, instead Board Replacment is all that is generally done.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Logic board? Are you referring to the Main PCB (BU board I think). This issue is caused by the Timing Control board (T-CON). It’s the board directly on the panel that connects by LVDS cable to the Main PCB. Not sure if it’s a part you can purchase separate from the LCD panel, but give it a whirl… you never know. I hope this was of some assistance.

Distortion in lower part screen (blurry) after powered on


It sounds that the CCFL lamp at the lower part is faulty. The fault is with its back-light itself. Check it. If you wish to get more details about these type of faults to LCD TVs, check the site linked here. It has stap-shot illustrations to these type of fault to LCD TVs; which I cannot include here by this window. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by type in the Brand name to your set in its search box, or view it in Mosaic / Timeslide / Flipcard option.

Three suggestions:

1. Try to hook cable direct without box to see if same problem---ie the box might cause this problem.

2. Check to see if it does it with DVD or when you change active inputs.
3. If number one contact cable provider as box may be your problem.

There are replacement screens available but I don't know if you'd be able to get an exact replacement for the broken one, but anyway they're expensive and you might as well just buy a new monitor.

Sony KDL-46XBR4 right 2/3rds screen darker, motion blurred


Hi Ron, thanks for describe many valuable details. You suspect something wrong with the fluorescent tube, if it is true, shall be dark on top or bottom, not left or right, also the problem with the backlight the TV will shut off and the timer LED will blink 6 times.
I think there is the bad connection inside the panel or the t-con board, only think you can do is try to reconnect the wires under the aluminum foil (see the picture) or replace the panel.

Sony TV LCD screen blurred down one side when switched on and then after warm up appears to fix itself.


My KDL-52W4100 just started doing the same thing. It blurs down the right side of the screen, then goes back to normal after it warms up. Does anyone know whats up with this?
