This is a ~ 4 year old HP Pavilion laptop with LCD display.

There is a bright vertical area on the left end of the display that is
incongruous with the rest of the display. It is only on the left end.

This image also shows the lighter central area of the display which is an
artifact of just viewing it on-center (or nearly). This phenomenon can be
ignored.

Is the stripe due to LCD problem? Or...?

Thanks.

It is such a terrible photograph that it looks mostly like a reflection
of something white you left on your desk off bottom right. It doesn't
look abrupt enough to be an LCD connection defect which tends to give
very sharp linear errors on bit/byte/word boundaries.

Looks to me more like a physical fault with the backlighting optics. An
impression heightened by a dark ridge to the RHS of the brighter patch.

I would agree ! Probably a defect in the backlight tube/tubes.

I've seen dark bands before (burnt out tube) but never a bright band. I
suppose all but one could be dimmed...

Thanks,

The tubes blacken at one end more than the other, so the brightness gets
turned up to compensate causing a bright area at one side. Double tube
displays do the same but because one tube is at the top and the other
at the bottom the bright area tends to be towards one corner.
