Hello,
If you have substituted the tubes into the wiring ao the side tubes and they work correctly, then you need to check out the wiring and connections on the top tubes. If these tubes are fluorescent then the problem may be down to the starter needs replacement, if this is the case you can check for this using one off of the side lighting. The starters will more than likely be 110/115 volt make sure you get the correct wattage for the lamps.
The only other cause could be that the cholk (ballast) is faulty.
