I have a B&W 5" CTR Nexxtech TV, model 1612002 (used as a lobby monitor), which when switched on, only displays the top half of the picture normally, while the bottom half is squashed into a narrow bright horizontal band.
You can sort of make out that the rest (bottom) of the picture is upside down. After it's been on for a while, the bottom half starts to extend further down, and becomes right side up, but is still squashed, so a 1/4 of the screen remains blank. Other than the brightness and V-hold, there are no other adjustments inside or outside.
Does anyone have any ideas where to look for the reason for this? I have an electrical background (not with TVs though), so replacing parts would not be a problem. Any hints would be appreciated. -Rick
