Caleb,

It's really  not that hard, have you a service manual? if not, email  
me. direct


I have removed the screen assembly from a lombard to work further  
inside. you just need to go slow, have the right tools and a  
large tabletop to lay it all out on as you go.

not sure about the 190, but the Lombard display replacement is a breeze. The
most difficult bit is removing the plastic top cover sitting between the
speakers to unveil the inverter, without breaking the little plastic tabs
that hold it into place, so pay extra care at that step. Run a google search
for  to dig an easy to follow tutorial (Pismo == Lombard
as far as display replacement is concerned).

cheers and good luck,
gianfranco

Re: Lombard display lines

[Caleb Cupples]

Dan,

Don't be sorry. I was expecting to replace the LCD eventually, so it's 
not like I was completely unprepared. The lines don't even show up on 
white now, so I'm not going to worry about it until more show up.


However, I'm still curious as to how hard it is to change a Lombard 
display, compared to rebuilding a PB 190 and soldering that little 
power connector.


Thanks,
Caleb

single lines of pixels = failed LCD, cure = replace

Caleb, somehow or other you damaged the LCD when you cleaned it. There
are glued-on flat ribbon cables connecting the LCD's edge 'wires' with
the LCD's onboard driver PCB. Those glued-on connections can fail or
short, leading to anomolies such as your LCD displays. Just takes one 
. .

sorry

Sounds like a line of bad pixels.  Can be caused by bad cable or VRAM IIRC
but is usually an LCD problem.

Did you let any liquid drip down on the edge of the display? wen you  
clean the display you need to wet the cloth and not the screen.

I dont think the fix is not on this e-group.

Please give me some hope, or a fix,
