When the tv is first switched on the picture is perfect, after it warms up a white strip appears horizontaly across the the centre of the screen. In this strip the colour seems perfect, outside of the stripe the scene has a greyish tone, colours are muted and bright areas such as light, fires, white clouds have a silver tone. In dark scenes this is not too noticable but in bright scenes it can be very obivious. I have spoken to Sony Reps but they don't have a clue and can give no guidance on the problem or possible repair cost. The tv was transported recently, but it was handled carefully. Can you help?

Hello, I have exactly the same problem with the exact same TV, white screen for about 15 minutes and than image appears perfect as if nothing happened. I have asked an ebayer which sells TV parts and he suggested it could be a main board or tcon board. I am quiet hesitant to fix my tv, but if the tcon board would fix it, i'd go for it. Did You manage to solve the problem yet?
I can't tell you how to fix this set, but I can tell you that its not a "lamp" issue as this doesn't have a lamp. Its a 3 picture tube projection TV. the three tubes are in a red green blue format, and average about $175 for each one, not including the labor to install them. your problem, may not be the tube, but just a power supply problem, but there is a chance it is.
Ahh the old rolling picture problem. If this set has a Picture in picture feature, your problem is on the PIP module itself. There is a kit of surface mounted capacitors that need to be replaced If you have some soldering skills you should be able to do this your self, but if you do not, I advise you to get someomne who does as most of these PIP modules are not available any longer. The kit can be purchased from http://www.mcminone.com/search.asp?keyword=Mitsubishi+PIP+kit&btnSubmit.x=6&btnSubmit.y=7 Good Luck
