obc backlight help

i have 2 obc's and none light up.
i can see the display,but not clear or bright.
all the digits work on both and so does the button on the indicator stalk.
i't reads 7.0c temp,[correct]i have changed the bulb with a working one in between the screws in pic,i removed the white thing and it has a circut board inside,so i put it back in.
the obc continued to work with this removed.
so i think this is where my problem lies.
is this the part i need to replace or can it be repaired?or is this not the part that causes the prob?any help here is welcome.

Re: obc backlight help

the bulbs for the display are on a circuit board on the side of the unit at the top corner
long nose pliers on it and slide it out,
the bulb you changed lights up the buttons,

Re: obc backlight help

You can get the light boards from BMW around £22 or you can get bulbs and solder them yourself for around 80p. The correct ones are 5v 60ma, if you want I'll have a look around for my "spare" bulbs, I got them from RS Components and they only sell them in bags of 10. The part No is 360-7890.

Let me know and I'll have a look emoticon
