PLEASE get someone that knows electrical or electronics to fix it! Most of the people I know that have the background can fix it correctly in about 10-15 minutes.

Hi, did you make sure it was the right lamp the reason is that theres two types of lamp one that shoots the light wider and another that concentrates on the center.Also check the ballast the main power of the bulb it comes to happen that when u put in a new bulb the ballast is not able to provide enough power to light up the whole screen.
