I have a Bravia KDL-52w4500. Over the last month I have started to get more and more horizontal line across the screen. These do not go away. What can I do to fix this

Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

the ribbon flat connection tapes that connect the led panel driver to the panel have prob delaminated
this cant be repaired easily and you would need to replace the panel

The horizontal lines on the screen is a symptom of failing LCD panel, it will get more lines as time goes by.

I have the same tv model KDL-40W4100 and around the same age. At the moment I have 16 of
these horizontal lines over the entire screen and they seem to be grouped into 2 lines per row. They are also around 4 inches and two pixel rows high. I have been looking over the Internet for months and found nothing to troubleshooting this issues. In the last few weeks more and more of these groups of lines have been showing up and now i am up to 16 of them and it is becoming unwatchable. Any help from anyone would be greatly appreciated. I also attached a picture to describe it better. Thanks!

Yeah we have the same exact problem here. Defective TV....ours would correct itself after 30 mins, but now it's blurry all the time. I'm never dropping 2K on a SONY tv again.

Are the lines all the way across the screen? or just a few? Solid black - or trannslucent?

Like this??


Horizontal drive has either data, voltage, or control problem from the pixel registry circuit......get it serviced before the problem spreads causing further damage.

However, in all likelyhood, the panel itself is bad. The Bravia line has had a bad rap about the faulty displays, and at $1800 replacement (plus labor) - it may be time to call SONY direct to complain!

Thanks!!

I'm having the same problem. I have noticed on mine that the menu when brought up is clear and I can see it perfectly. The picture on all the inputs is just as described above though. BUT, like I said I can see the menu just fine. This leads me to believe that it's not the panel. Anyone have a solution to this, or at least know what could be causing it?

try call sony get one time warranty.maybe lcd panel bad or call bestbuy in home service

try cleaning T-CON Board to Lcd panel cable
