Question about Sony Televison & Video

1 Answer

I have a sony lcd tv (kdl-52w5150) with audio and picture, but the picture is only the top portion of the screen. It has horizontal lines for most of it.

Could it perhaps be the t-con board or is the lcd panel bad. I can send a picture of the screen if you'd like

I will try a new T-CON first, if it did not fix it, it could be a defective LCD panel.

Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER
Take care in solving the problem...

Sounds like a T'Con fault itself. Re-seat all the incoming and outgoing flat cable wires to T'Con. If it do not help you, replace it with a new one of same part number. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

Model# kdl-40w4100 Serial # 8051767 2 years old Horizontal lines in 4.5 inch blocks at the top of the screen


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!
