You should have a 1 year warranty from Sony. Call them before it expires. This is probably a LCD panel issue.

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.

we have the same exact tv and it is not even a year old. we are told that it is the display panel and it is a well known problem with this tv. we were also told that there is a shortage of these parts. they had 283 on order, but only received 35. you need to call sony and tell them that you have this problem. they should warranty this for you even if your tv is 3 months past the warranty period. since this is a well known problem with this tv, keep on them.

Testimonial: "It in fact was a part of the lcd panel...the t-con board. I was able to research it and bought a box of parts off of a tv like mine and fixed it. Ron"

it sounds like your back light might be going out. You might be able to fix this by installing a new backlight inverter board.

My Sony KDL-32M3000 has ghost (dark red) display with slow motion picture. What could be the cause and how can it be repaired. Thanks


Thats usually caused by bad flex tab bonds on the LCD panel itself. If you search for flex tab issues vidoes it will show how the pisture can get slow motion in areass as well as double images in that area.

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.
