"CFLs" Compact Fluorescent Bulbs (with built in ballast) must be labeled as dimmable to be used on a dimmer circuit.
Traditional fluorescent fixtures must have a dimmable ballast installed inside and can be used with standard fluorescent lamps.
Fluorescent lamps must be sized to match the ballast. CFL's are matched at the factory, but others are not. Older fluorescent lamp fixtures have a ballast inside. A type rating is to operate (2) 48 inch / 40 watt lamps. Newer fluorescent lamps are rated for 32 watts, and these will not work - or will have a greatly reduced life.
If you installed CFL's, the first thing I would do is install regular incandescent lamps and see if it works as expected. If not, something else is wrong - otherwise - make sure you've got the right lamps in the fixture.
Remove lamp and look to see the socket the lamp plugs into did not get bent out of position---just check to see if it went in right and after that you put the door back(set will of course not operate if door or cover removed).
If we assume New lamp good and installed correctly the next possible issue is the Ballast which powers the lamp--Not easy on this set to check voltages---should have a plug with over 200-300 volts from power supply going to--the two wire plug from the lamp goes directly to it.
I had the same problem took it in and it was the bulb had over heated and blew out. The bulb is $199.00(here in wisconsin).After teh repair i called hitachi they told me i could have done it myself without having to take the tv in...Hope this helps.....
The best instructions for replacing the lamp can be found in the

Your bulb may be blowing because of airflow issues or power cycling issues, first does your outlet get switched off at any point in time? if so you may be killing the bulb before it cools, if you turn the set on/off alot and or restart it after off quickly this could lead to permature bulb failure, if the original lamp was not replaced with a proper lamp to match the ballast it could blow the bulb. If your tv is too near a heat vent or the airflow thru the set is not adequate it could blow the bulb.
