Help with 19" Viewsonic PS790 works but get cliccking
 

I have this monitor that once evry few minutes gets a clicking sound and a
raster cycle thru the screen. The clicking sound appears to be coming
around or inside the flyback.

I have redone all of the cold joint and looked for bad active comonents and
bad electrolytic capacitors.

Could it be the flyback itself or a a non electrolytic capacitor doing this.

What is your past experience with a symptom like this?


Thank you for your help

I have a similar prob with the same model PS790. After 5 years of operation it started to make the clicking sound and the screen shrinks. A technician advised to replece the flyback, but I couldn't find it.

Did you find a solution? Please help...
