I am a UK(London) resident.I purchased the below mentioned tv in sept. 2004. From early 2006 the picture is periodically displaying slightly diagonally running lines across the screen from top right side to the left bottom- the colour of lines generally slightly green; as channels are changed they become white. Often, after a while, the screen starts becoming brighter until it becomes snowy white and the picture gives a hint of collapsing from the right and the left into the centre into a thin line running from centre-top to centre-bottom -this has actually happened on a few occassions. In between all this the picture has been quite normal. Recently, I called a engineer and despite the fact that he charged me £50 the problem has not dis-appeared. He has ruled out a faulty tube.There are a couple of things that I want to add:
1. When I have used the stand-by switch to put the tv into stand-by mode there first appears a thin green line running from centre-right to centre- left of the screen. Then a small red spot light appears exactly in the middle of the screen.
2.The sound, of late, has started to diminish in volume around the time the picture is affected by those diagonal lines- on occassions there is no sound. On, either, using the stand-by switch or swithcing the main tv button off and on the sound may return. During the early period of this problem I stopped using the stand-by switch and noticed that I maintained a good picture quality for longer periods!
3.In the beginning of this problem I noticed a lot of static electricity discharge on the tv screen -those days I had a electric fan fed from the same multi-socket mains connector. I have ,for long now, removed the fan into another room - the problem still persists.
Could you kindly tell me what I should ask my engineer to consider/do with the tv when I next call him.
Thank you.
