Re: Hannspree HF289H With Unstable Picture

Here are the pictures, thanks....

Hey all,

I have a Hannspree HF289H monitor that started acting strangely a few days ago.

Regardless of the screen resolution, refresh rate or input used (hdmi, VGA), every 1-3 minutes the image will roll vertically for a few seconds. It reminds me of an old VHS tape.

I have also seen the upper corner of the screen turn white and spread outward, then just as suddenly the color will revert to normal.

The logic board and power supply looked fine, no bulged capacitors. What could be causing these issues?

Any help is appreciated,...
