Are those the
same LED's used in the HP 16500 series touchscreens ?
Not having seen inside a 16500, I don't know.
I have extraced the faulty LED (you can do this without removing the from the PCB, thankfully. I didn't fancy having to
desolder all
21 X-axis LEDs). It's a flat transparent package with a lens 'bubble' on
the output
side. I think it's commonly called a 'side
viewing' package.
Yest those are the same package.
As you may
know I updated my 16500A to a 16500C version with a upgrade
kit from Agilent.
Upgrading included changing the touchscreen PCB, so I've an A-version
which I don't use or maybe one day will part out.
Why do you chnage the touchscreen PCB? Is the new one a higher resolution something?
When updating you get a new front which includes the touchscreen parts..
I think change is the LED's are the same, let
me know If you want some
of them.
THanks for the offer, but it appears that both RS components and Farnell LEDs in the same package. I will measure up the old
one to check, and if
they are
the same I'll order a few replacements to try
them
I'd rather have a sourve of new speres than have to depend on what I can
raid
from old boards.
Yes I agree, but sometimes ...
