MX-5020HPM repair

I'm looking for diagnosis based on maxent 5020 HPM video Behavior it flickers at startup for approximately 90 seconds and then goes to a solid blue screen but at exactly down the middle, at half of the screen horizontally, left and right... , it is split where one half is different.  in the left1/2 looks like the darkest black is been replaced with a green pixel and then on the right half it is almost a sort of a fuzzy, jittery kind of aspect to it and the gamma also seems to be off I have photos of the behavior and looking forward to doing the repair
