[ICOM] Replace lamp in S meter 756 Pro

[William Chapman]

You will need to take off the front panel from the main chassis then remove the plastic front panel
from the sheet metal that it is mounted too. Then you will need to remove the PCB that the meter
is attached too.  The lamps are 4  LED's 2 each in series with each other along with a series dropping
resistor. I have found in the past you may have 2 of those LED's that are open and happen to be one
in each series string.
Sounds complicated? It is and you need to be careful removing and plugging in those ribbon cables.
Best help would be to get a service manual first though.

My S-Meter lamp is out in my IC 756 Pro. Removing the top cover shows NO access to the 
meter so the lamp can be replaced.

Anyone have a suggestion?

Perhaps a site where I can go to obtain instructions? I’ve tried the usual with no success.
