Hi Guys.
Im chasing a bit of an odd problem on my arcade monitor, the chassis is an Intervideo LS250, and seems to be working, or well sort of.
Did a tube swap because the old CRT was weak, and noticed the top of the picture was missing, swapped back to the original tube, and same fault, so something has to be up with the chassis, i am feeding it with a pc with soft15khz, and a resolution set to 320x240, the chassis has been re capped.
Controls on the chassis seems to be working, but no matter what i change there is always missing the top of the image, as it can be seen on the attached file, the top of the circle is incomplete.
(Picture is of the original tube for the chassis, and very weak)
Any suggestions to what my problem could be ?
Kind regards
Ronni
