I'd not risk that backlight. Maybe the current ones weren't bad but they were damaged - e.g. by the high voltage or high frequency. Maybe it is just not lighting due to the frequency...

if all fails just buy an inverter this is a black
box you can get them from the efoil companies they do them in 5v and 12v
and you just solder to the 12v line and ov or 5v
and ov
this has a lead that goes to the invertor which is
in a black box then afix the black box in side the machine its insulated
so can short any thin
they are only aboy £4-8
i did this to a fz1 keyboard as the invertor in
them is dc to dc
efoils will work with dc but the lighting life is
halfed they burn out much quicker
i always test my efoils this way
aswell
as it will work from a 12v battery
i check the efoil before i solder them in to make
sure they are working saves a lot of time
