The TV picture stared jumping. Then lines were going across the picture. Tried to shut TV with the Direct TV remote and it would not turn off. Control switches on the tv itself do not work. Power - Channel - volume - etc nothing works. Have to pull power cord in order to shut it off.

We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.
This sounds like a loose solder joint, or overheated component. I know this may sound like a **** question, but have you tried tapping the TV to see if it goes away? If it does, you will need a tech to re solder the loose component. I have also seen this type of line and color bleed problem, believe it or not from poor cabling or loose connections.
hi all .ive had the same problem,a thick black line down
screen.sometimes it flickers from top to bottom and other permantly in
view.but i have solved it.forget your ic boards and taking apart tv.have
you got either a ps3 or wii connected to tv.if so unplug power lead
from socket and relocate in seperate socket.make sure the lead is
completely free of any other leads and you might just find this works.i
think the power lead creates some sort of frequency that the tv picks up
.good luck hope it works
