working on a viewsonic lcd model va720 with a strange problem; it starts out fine has a great picture for aprox 1 hour then half the screen right side gets distorted & whitish
it is from top to botom & takes up half the screen.If you turn the monitor off then on again,picture will be good again for 5 seconds then distorts again.I have tried to freeze components but no luck. please help if you can.
thanks.....tbmanitou
