I have a 2 year old Philips Roku 32" model 2pfl4664/f7 TV. It works, but has high contrast and washed out screen with some jittering and occasional flickering with bright white. Did factory reset and tried brightness and contrast but no resolution. Could it just be loose connection on the screen? Any suggestion greatly appreciated.
Music Man50 it would really help if we could see what your screen shows. Couple of pictures or a short video posted with your QUESTION will help Adding images to an existing question Most commonly this would be a T-con board issue but can be a main board or even panel issue.
