My screen has thin lines all across it. Video Card?


If you see the line the second the
screen comes on then i have bad news
the L.C.D. has a short to ground in that
row , difficult to repair that problem.
I recomend you take it back to the
place you bought it and Demand a refund
or a replacment . That what I would do.

you need a green CRT thats whay you have the white kind of concave lines with the green screen. You can try adjusting the green screen control but you need anew CRT ( tube) the speaker cover has two plastic plugs that get removed on the lower edge os the grille which covers the two screws that hold the grille on. If you need more assistancr or where to get a green CRT let me know as I have a link that has some green and red Tubes for your model.

Hello im having problems with my sony wega


It sounds like you have a loss of green. This could be caused by the green gun in the picture tube opening up or the drive circuit for the green gun gone bad. Stargazer
