Re: Wallstreet II video problem

[George Mogiljansky]

The Apple Service manual says first reset the power
manager. 
For the 13.3 screen, start with the display cable. 
If you have a 14 inch screen, start with the inverter
cable, then the power cable, the inverter board
(replace), replace the display, i/o logic. 
I just bought a replacement screen on eBay. Mine is
dim and a replacement of the backlight seems
problematic One user did it but dust got into the
screen and it's pretty bad. 
Does anyone know if the 14 inch backlight is
soldered-in or just clips in?

 A used-to-be intermittent video problem showing up
 on the display of my 14
 Wallstreet is now an all-the-time problem.
 
 What starts out as horizontal noise lines during
 boot seems to rotate 90
 degrees at boot-complete-tike manifesting itself as
 vertical noise lines.
 
 Some months ago when it was intermittent and a
 reboot or two always made the
 noise lines go away.
 
 Now they're here to stay.  Any suggestions (e.g.,
 reseat/replace video card,
 reseat/replace video ribbon cable, upgrade to 17 G4
 PowerBook [my
 favorite!], etc)?  
 
 I've got a Picture 1 screen snapshot I can email
 anyone interested in
 seeing a sample desktop with the vertical noise
 lines (digital pix just
 didn't show the lines) or I can ftp it to a web site
 if G-Books (or similar)
 offers such a feature (my website is off line -
 vendor hard drive failure).
 
 Thanks.

Re: Wallstreet II video problem

Problem solved!  

The power manager reset didn't work so I took the sucker apart and removed
every component and cable I could find.  And while I was at it I reflowed
some more solder on the power supply board 'cuz the repair job I did a year
or so ago where the power adapter plugs in was starting to show cracks.

After reassembly, powering it up (with some trepidation) was very rewarding.
The screen illuminated faster and the vertical lines are history!

Only downside is I lost my excuse for a new 17 PowerBook.  Oh well.  Maybe
later this year...

Thanks for the suggestion George.
