Hi All:

I am in the process of repairing a GM automotive instrument cluster. This
particular car has a vacuum flourescent display to indicate gear selection
(PRNDL). This display is inoperational. Observed is a missing component.
There is a section of the PCB where four seemingly identical components were
set up. One literally fell off the PCB due to poor soldering. The other 3
were easily lifted off with light pressure from my thumb nail. My job now
is to try and obtain a replacement component. My main problem is that I
cannot positively identify the part I need. I suspect that it is a high
grade resistor, but I have never seen one of these before. A picture is
located at the URL below:

http://bkos.home.infionline.net/Component.jpg

The part is about 1/4" long overall. It is a cylindrical shape with
slightly larger ends than the overall diameter. It reminds me of a very
tiny copy of a cartridge fuse used in household power centers. The center
section is colored black. The ends are colored charcoal. There are two
similar devices elsewhere on the PCB that are colored brown with bright
silver ends. There are no readable markings at all on any of the
components.

Two of the components I have measure 151.5 ohms. The third measures 121.6
ohms.

Can anybody offer any suggestion as to what this component is?
Recommendations for a reasonably obtainable substitute part? I'll have to
guess at the value of the missing part, but I need to konw what I'm looking
for.

Any and all help is greatly appreciated.

Regards,
Bob

Bob,

Looks like a surface mounted resistor.

Thanks for your reply. I have looked for a resistor like this but cannot
find one. I am thinking that simply installing a standard axial lead 1/4
watt resistor might be an acceptable substitute?
