I have a hp omni 27 all in one. Had windows 8 upgraded to windows 10 didn't like it so went back to windows 8. After about a week or so of going back to windows 8 the screen started to give a flicker periodically then it eventually went blank. Not sure if windows operating system has anything to do with it anyway it powers on fan runs but no display. It abt 3 1/2 years old. Took rear cover off nothing seems out of place or dirty. It's a 27-1210xt. Can anyone help? Thanks
