hitachi l32hk04u- bottom 2/3 screen is black. help!

Hi all,
newbie here please be gentle lol.
I have a hitachi l32hk04u hd lcd tv.
been a brilliant tv, untill while watching a dvd the bottom 3rd of the screen whent green. Could still see through it though.
a few weeks later it increased to 2/3 of the screen.
then instead of jus looking filtered, it is now just completley black. Can just see the top 3rd. Sound and functions still work fine, just the black screen.
Help would be greatly appreciated!!

Welcome to the forums.

I'm guessing you're from the UK as I can't find any service info in my regular channels nor do I recognize the chassis.

Are you going to open the unit and try repairing it ?
Did the dead area creep up slowly or was it just larger one day?
Was the line between the picture and the dead area jittery ? By that I mean is was that line constant or was fluctuating up and down.

It could be as simple as a connector between the LCD display and the driver board need a reseating or it will need the driver board replaced.

In the picture below is the display driver board. You could try removing the metal cover and reseating all the connectors on that board...... carefully and with unit unplugged.

If it's not an intermittent connection then it's a defective board at which time you'll have to decide if you want to try locating a board or replacing the TV.

Leave the bakc off for now. It's not hurting anything.
