One day my tv started having white lines in various places, then one day the scrren went white but still has a small line across the top that works fine


Hello,

The problem is "Vertical Over-drive" and the white lines are vertical retrace lines. What has happened is a component failure between the vertical oscillator and the vertical driver circuit. The component is usually a capacitor that is leaking and allowing voltages to appear where they shouldn't be.problem component is leaking and allowing DC voltages to appear where they don't belong. It's causing the vertical driver transistor to run "flat out" and will ultimately burn out the transistor from internally generated heat.
Hope this help....

I have an Optima Model EP719 Projector. Suddenly I am getting white vertical lines and can't find a solution for removing them.


I would try switching out the DVI cable first. It could be faulty. This would be the easiest and cheapest solution to check.

Follow up on the Optima 719 with vertical white line


Hi Abouttime

Tapping can fix most electrical things for a very short while - unexplainable !

But I have been working as a authorised service provider on mos brands of Projectors for over three years now and in all of the times the white line was a faulty Mainboard.

This is just my opinion and I only answer and provide a free service to those who are in need.

Wheter you take my advice or not is entirely up to you.

Kind Regards

Marrie
