Question Dash Display, Speedo, Tacho, Instrument Cluster not working

Hi peeps...

A search has only produced a fix for the electronic SI board display not showing properly.
What I am after is a "How To" on replacing the batteries within the instrument cluster as it might be the cause to my problems.

The fault is: None of my Dash Display, Speedo, Tacho, Instrument Cluster, Fuel gauge works... The lights on dash for indicators don't work even though the indicators are actually working, the main beam (green light) doesn't work but the high beam (blue) light does work, the "Check" (orange) light also works.
I noticed one day i went to use the car, just switched on and nothing so I wasnt using it at the time this fault occured.

I have been told by a breaker that sometimes the onboard battry/battries have died, aparently they have been know to leak all over the board and thats what causes the lot to fail?

Anyone with any knowledge on this subject?
Can i open up the dash display or is it sealed?
Are the battries hidden (if so where)?
Is there a online "How To"?
Or is it all porkies lol

It's a E36 1994 325i M50 (The last of the early breed)
Incidently the dash display has a white rear to it (apparently some have blue or green)

There aren't any batteries in the cluster that I'm aware of. With the E36, the vast majority of problems like this have to do with the plug connections in the back. Try removing and resetting all three connections in the back and see if it helps. If not, you probably just need to get your hands on a used replacement cluster.
