My d9200 monitor will have a fantastcic picture, then will slowly lose focus until it looks like crap, then will snap back into perfect focus again. Ive heard it can be neckboard or flyback related. I was fortunate to have another non working d9200 to pull parts from. Switching the neckboard causes the focus problem to go away. So its a neckboard issue. I tested all caps and they test good with my blue esr reader. Any other components on the neck board that can cause this?
