The picture on my mitsubishi tv is only appearing in the left upper corner of the tv. It is a very small picture (but it is a normal picture) the rest of the tv is black. Everything seems to be working fine but I cannot get the entire tv to show a picture no matter what I change. It started last night and I am not sure how it started. Also note: my remote control is broken, it does not allow me to go control panel etc, im only able to control the volume. Can you tell me what I need to do to see my whole TV again? Thank you
