Hi All,

I have an NEC FS-6390 here that has no vertical.  The TV has just a white
line running across the centre of the screen.

Has anyone had this problem with NEC's in the past who can offer some
suggestions?

Thanks in advance.

David.
I have repaired a few FS-6390 with this problem.
Most likely IC401 is crook, this is a LA7838 vertical output chip.

Also check,
R522 2.7ohm 2w fuseable.
R523 2.2 ohm 1/2w fuseable.
R427 100 ohm 1/4w fuseable.

Replace:-
C609 100uF 16v
C533 2.2uF 160v
C611 22uF 25v
C411 100uF 35v
C607 220uF 10v
