Thank you.

It smells like false contact! A half image looks like an interconnection concern between the display and the source, you have to open and look if a ribbon cable or a connector cables, see welds have not let go somewhere ... A good visual on interconnections. Does it do it at ignition or more later when hot? Have a look first!
 
It seems the screen error is segmented in 3 rectangular areas and not common to just rows or columns, which now makes me think , this is a page buffer error.

Solder faults are the biggest production problem in general, and it is possible a marginal escape found your way. If you wanted to diagnose that, it would take a wizard's touch to press on chips and traces to cause or change similar effects on the monitor.

Low probability of repair.
- better to consider using your TV display or shop around
