    What's an LCD Controller?

  • Anonymous Jun 17, 2010

    Last question, so if the LCD "screen" isn't damaged, could the LCD Controller be bad causing this Black line? Or can that not be possible?

    LCD Controller is circuit board that is mounted on top center of lcd panel if you look its rear, it would be covered by metal shield.

    It is possible that lcd controller (T-Con board) is main cause of that black line and can be checked by swapping that board.
    In Sony part policy, lcd controller board is included in lcd panel.

Sony HX750 has green line running vertically all the way down left hand side and black line running horizontally across top of screen

The fault is with its main power regulator section circuit itself. Check all the electrolytic capacitors there. Replace them. Replace the main filter capacitor too.

Line thru screen

The LCD Panel must be replaced to fix both problems. The cost in doing this would exceed the value of the set. I recommend not putting the money into it.

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...

Lines on tv screen

Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad
