I reported on here not so long ago about intermittent horizontal ripples appearing on my Mitsubishi Diamond Pro 740SB screen. This got worse recently whereby the ripples changed to waves and the picture started contracting in a vertical manner towards the centre of the screen from the left and right hand side.
Last night the picture disappeared entirely and all I have left is a very thin vertical shaft of brilliant white light down the centre of the screen, which tries to widen but never quite makes it. The monitor is only 14 months old. What has happened to it please?
I have changed over to an old Packard Bell monitor which is showing a picture, so I am assuming it is not the graphics card.
Please bear with me as I know nothing about the technicalities.
