My monitor is just over three years old and has suddenly developed a problem where all it does is showing a flashing vertical/horizontal image (see below) that pulses about 5-6 times per second. This is without any input cables attached. If I press buttons on the monitor to enter its diagnostics mode, which apparently puts various colours on the screen, then I can see the white parts of the image do change colour but other than that it looks the same.
I've searched images across loads of sites and can't find anything similar. Any ideas? I did open it up and nothing looks obviously wrong, but I don't really know what I'm looking for. The only thing I did spot is that the larger capacitor in the image below has the visible lines on top of it (the smaller ones don't) but I can't see any obvious bulging.
Thanks for the help
Mike
