The display is showing Ready to run inspect battery. Changed the battery., display stays the same

Did you recently clear the trouble codes or disconnect the battery? Once all codes are cleared, the computer will not display systems 'ready' until they go through an evaluation cycle. Some of the systems require a certain number of drive cycles before they will display 'ready'. A drive cycle is usually starting the engine from a cold start (based on coolant temperature) and driving until certain conditions are met. I don't know what the requirements are for your car, but my 2003 pickup truck requires more than 10 drive cycles before it will make the O2 sensors and evaporative emissions 'ready'. Most states only require that a certain number of systems are showing 'ready' to pass emissions certification.

Jerry, disconnecting battery will do the opposite of putting vehicle in readiness state, the only way to get in ready state is by drive cycles or a technician with a good scan tool, to make the monitored items run on command, which can put them in ready state.

I have the very same problem and I have no knowledge of the backlights of LCD panels. Is there any way to fix this yourself?

Most of those chargers have a fuse in line between the battery and the charger which you should check. They are two stage chargers meaning when there is a large voltage drop, they go to a high rate charge until battery voltage reads about 14.3 - 14.6 VDC then drops to a float volatge and normal float voltage should be about 13.33 VDC. When they go to a high rate the light turns red, when they go to float the light turns green. When the fuse blows the light stays green because it doesn't see any voltage but the charger isn't doing any work.

Unhook battery for about a minute them reconnect this will erase all codes

bad wiring and anything that stays on-du a complete inspection of vehicle and have it scanned--disconnect batery at nite to save charge

It usually takes more than one drive cycle to clear all monitors to "ready".The vehicle may take multiple "from cold" drive cycles and hundreds of miles to clear all.Drive normally with varied driving and include long coasting down stops.Buy a cheap scan tool ($35) and check monitors as you drive.
DO NOT CLEAR CODES or run the battery dead or you will have to start over!

The below is taken from another site written a year ago:
What you are looking at is the Service Indicator. The green, yellow and red lights let you know when service needs to be performed. The green lights mean everything is still good. The yellow lights mean "anytime you're ready." The red lights mean do the service ASAP. There are also two other lighted areas. One says "inspection," the other says "oil change" (or oil service.) An oil change is an oil change. However, there are two inspections: Inspection 1 is normally at every other 15,000 miles; Inspections 2 is at every 30,000 miles. Your local BMW dealer should have a pamphlet listing all duties performed for each of the services. Inspection 2 can run you around $400-$800 depending on the service station/dealership's labor rates. Inspections 1 should be around 1/2 of that. You should have your oil changed about every 5000 miles. Dealership oil changes can range from $35-$65. A BMW that is well taken care of will last a long time. 

FYI, don't be surprised if the SI (service indicator) board decides to **** out one day. I'm surprised to see yours is still working (they usually die within 10 years unless someone went thru the expense to have it replaced.) If/when it does go, just gauge your services by the mileage intervals I've listed above. I'd also recommend when you stop into (or just call) the dealership, go to the parts department and order an owner's manual for your BMW. Should be less than $20 and get to you in about a week unless they have one in stock.
When the service tech has performed the necessary service(s), he will reset your SI board so that only green lights are showing.
