I have a Samsung 40" lcd TV model le40r87bd and the picture has recently started to ghost and become blurred , is it repairable and if so how much does it usually cost?
It only seems to be doing this through the scart socket into my cable box(cable box been checked by virgin media) dvd player picture is normal and its through hdmi . I don't have hdmi cable box

Firstly check your cables.
Usually Ghosting is caused by a bad connection/cable.

Checked all the cables and also had virgin media out who checked cables too :-(

Have you switched the DVD one with the TV one, but kept the same rear TV connection, as you mention that the DVD works fine ?

Does this model have multiple SCART connections on the rear ?

Yea tried that also,swapped cables around with no change in picture

Hmmmm, scratches head.

The only other thing I can think to try is to default all of your settings on the TV itself.
I would also ensure that the Vbox settings are correct for the required signal output.

Do you use the AV output on the Vbox to send the signal to another TV ?
