Question about Hitachi UltraVision CineForm 55VG825 55" HDTV
This tv has 3 small LCD screens that create the pure color images (RGB). Those images are combined to create the full image in the optical unit - an assembly of prisms, mirrors and lenses. In your case the optical unit is misaligned. You need to open the tv and find out what happened. If the problem is caused just by the position of the optical unit in report to the LCD screens then all you will have to do is to realign it - a screwdriver and a lot of patience is all you'll ever need to do that.
If the problem is caused by the deformation of one of the plastic prisms or lenses then this is terminal - since this can't be fixed , the entire optical unit will have to be replaced. A new optical unit will be extremely expensive - see here
