A white horizontal line moving from bottom of screen to top

Hi, I have a 46' Bravia Sony LCD, I bought it about 2 years ago. Recently I notice that there is a white horizontal line moving slowly from bottom of the screen to the top, once the horizontal line reaches the top, a new one starts from the bottom again. The horizontal line is not that white, a bit blur, can someone please explain to me what 's wrong, what causes it and how I can fix it and how much it will cost ...Thanks in advance..Hank

SOURCE: A fine green vertical line displayed on the Sony Bravia 46.

Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

SONY KDL-46W4100 LCD colour horizontal lines...


HI,
Your tv have problem with the T con board. The t con board drives the Pixels in the lcd screen . If there is some problem with the t con board then this can exibits such problem as you mentioned. Normally you can find the t con board in the bottom center of the lcd coverd with a metal cover. Its part number is SONY T-CON: E40951307. If its avilable then try to replace the same which will solve the problem. Its a regular complaint with the Lcd tv's. I have added the picture of tcon board.

Som times if there is any loose conatct in the pannel connection which comes to the t con board then also the same problem can occur. Before going to replace the board do one thing remove all the connections to the t con board and reconnect it. Some times it will solve the problem. If you need any more assistace feel free to conatct me through fixya.

The reasons for the fault may be due to:
  1. The Control PWB only causes this defect when the Backlight Control Signals are Output from the Control PWB.
  2. No LVDS signal may also result in this symptom.

Sony Bravia XBR 40" LCD


First, HORIZONTAL CENTER.
1) Press MENU.
2) Scroll to SETTINGS.
3) Scroll to SCREEN.
4) Go to HORIZONTAL CENTER. Move the picture to the right. Hopefully, the line will go away. Otherwise, there is a problem with the pixels or the signal processor. Call 1-800-222-SONY. Or, http://eservice.sony.com. Have a high-limit credit card handy for out of warranty repairs. Sorry about that.
