Right half screen blurry for first 20 minutes
After about 20 minutes the picture is fine and no problems occur thereafter. The issue does not seem to be affected by video source (cable, Roku, DVD player). Just before the picture becomes clear some jagged lines show - similar to what might be caused by interference. Our perception is that this warm-up period is getting longer.
Is dit een goede vraag?

Dale, this can be caused by bad caps on the power board.
