Picture has a grey box over about 80% of screen, then vertical lines take over and we lose the picture

The LCD screen is now broken and it would be easier to buy another TV than to repair the one is has lines on the TV's screen.

A defective display panel.

Video heads need cleaning

my colour is green why?

more likely to be bad LCD panel (very expensive), but you can try replacing the LCD controller first (around $80~100).

It sounds like you need a new screen.

Buy one on Ebay for 20 Euro (inclusive of postage)

youtube.com has great videos of how to change a screen.
You will need a tweezers and very small "philips" (cross/plus head) screwdriver.
Make sure the screwdriver has magnets....so that you dont lose some screws....they are tiny.

If you buy a replacement "LCD Screen Display" on Ebay then usually all the tools you need are included. (I just checked).


I also have just replaced my screen....screen was damaged...LCD leaked and lots of vertical lines on a now only WHITE screen.
Camera works fine now.

Check to see if the camera is still working.
Try taking some pictures....and then put the SD-card into your computer to see if the pictures are being taken.

this means the TV having picture upper part of the screen. problem may be -15 V to vertical deflection ic suddenly gose off and system control gose to stand-by mode resolder vertical out ic , -15 v supply line from the fly back and system control .

first adjust the screen knob at the back of the plyback and then check the screen ,if you see a vertical line ,then vertical IC is busted or else lose connection.

I had the same problem with my Lnt4071f. I called tech support and they said it was a faulty panel and the entire set had to be replaced. If you have your warrantly still use it, if not you may just be able to replace the panel, but its expensive.

hi there, working sometimes means there's a lose solder at the vertical section. see the vertical ic, check the board for some lose connection and cold solder. do some test. ty
