Hi all I am having a problem with my DV10. At first one vertical flickering white line appear on the screen, now I have two. I tried to use the tracking and it does not make a difference. I had my DV10 hooked to my satellite receiver with S video cable. The bulb is practically new (100 hrs of use) does anybody know whether is time to service it or it can be fixed by myself? Thx much in advance
